Trace Launch Research Notes
Working evidence file for the 2025/2026 consumer app launch research goal.
This is intentionally rough: source links, numbers, caveats, and synthesis
fragments that feed LAUNCH_RESEARCH_REPORT.md.
Research Rules
- Prioritize 2025/2026 examples and benchmark reports.
- Use 2023/2024 cases only when still strategically relevant.
- Separate verified facts, estimates, and self-reported claims.
- Translate patterns into Trace-specific decisions.
- Avoid importing tactics that conflict with Trace's product philosophy: no per-meal verdicts, no shame-based diet language, no unsafe medical claims.

Asia Quality Review (2026-06-16)
Main finding: the report was much stronger after the 2026-06-15 codebase pass, but still read like a US-iOS launch memo. The weak spots were:
- Channel bias toward TikTok/Meta/Apple Search Ads; underweighted Kakao, Naver, LINE, Zalo, WhatsApp, and Google Play custom listings.
- Platform bias toward iOS despite Android-first project history and APAC Android reach.
- LTV/CAC bias from North American subscription benchmarks; APAC payer LTV can be real but lower and more uneven.
- Food-data bias: no enough focus on hawker meals, Korean stews/banchan, sauces, soups, shared plates, rice/noodle bases, and drinks.
- Country grouping bias: "Asia" was treated as one market instead of Singapore, Korea, Taiwan, Vietnam, India, and mainland China having different launch mechanics.
- Regulatory/distribution gap: zh-CN was not clearly separated from mainland China readiness.
Working recommendation after this pass:
- Singapore = first APAC proof market.
- Korea = second only after Korean food-scan trust and Korean-native store copy.
- Taiwan = later zh-TW/LINE test.
- Vietnam = content/community learning before paid subscription scale.
- India = useful case-study market but not a first launch without Indian food coverage and localized pricing.
- Mainland China = explicitly out of first-launch scope.
Verified Product & Cost Facts (grounded in the repo, 2026-06-15)
These are checked against the codebase, not inferred — they anchor the report's economics and funnel sections. The earlier draft was written without reading the product and got the funnel and measurement sections wrong.
Unit economics (firm)
| Input | Value | Source |
|---|---|---|
| Meal scan COGS | $0.0036/scan (1441 in / 959 out @ Gemini 3 Flash $0.50/$3.00 per 1M) | prod api_call_logs, 109 scans Apr–Jun 2026; memory ai-cost-per-scan; ALGORITHMS.md cost section |
| AI COGS/Pro-user/yr | ~$1.30 (1/day) · ~$4 (3/day median) · ~$8 (6/day) · ~$26 (20/day cap) | same |
| Non-AI infra/user/yr | ~$1–3 (estimate, labeled — needs real infra-cost-per-MAU pull) | not yet measured |
| All-in COGS/paying user/yr | ~$8 median → ~90% gross margin | derived |
| Price | Monthly $9.99 / Annual $79.99, annual pre-selected, 3-day trial once/user | CLAUDE.md, apps/web/messages/en.json |
| Store cut | 15% planning base (Apple Small Business + Google first-$1M); 30% sensitivity | Apple/Google policy |
| Blended payer LTV | ~$49 conservative / ~$70 mid / ~$85 optimistic (60/40 annual/monthly) | derived; renewal is the only free variable |
| Derived payer-CAC ceiling | target ≤ $20–25 (3:1), tolerate ≤ $35 (2:1), $50 = yr-1 breakeven wall | LTV ÷ ratio |
| Implied CPI for $23 payer CAC | ~$1.20 (at 13% install→trial × 40% trial→paid) | back-solve — why paid UA can't lead |
Key takeaway: cost is knowable to the cent; the only thing that moves the CAC ceiling is churn, so measure renewal early and stop refining cost guesses.
Funnel / product grounding (firm)
- Shipped first-session order: onboarding → Plan Loading → Food Lens Reveal →
Sample Meal Picker → Sample Meal Result (running totals, FREE, pre-paywall)
→ Paywall → First Scan Prompt (post-payment; OS-notif prompt fires here).
SampleMealResultScreen.tsxrenders macros + per-condition lens readings with no payment. The earlier draft's "paywall-first" recommendation was a regression. - Analytics events already exist (
apps/mobile/src/utils/analytics.ts): first_scan_completed, scan_result_viewed, close_gaps_viewed, second_scan_completed, paywall_viewed, condition_selected, cancellation_* with days_since_trial_start. Don't tell James to "add" these. - Attribution is the real gap:
sourcehardcoded'organic'(IntroCarouselScreen.tsx: "paid + referral sources will hook in when attribution lands"); no MMP. Creator CAC is unmeasurable until this ships. - GLP-1 companion is free forever (D93) → wedge audience == free tier == lowest-converting segment. Acquisition ≠ monetization segment.
- Platform/locale: ships iOS + Android (project notes: Android-first), 5 locales EN/zh-CN/zh-TW/KO/VI. Report assumed US-iOS — flag the scope.
- Prod AI provider = Gemini 3 Flash Preview (verified 2026-06-16).
.do/app.yamlsetsAI_PROVIDER=gemini+GEMINI_MODEL_OVERRIDE=gemini-3-flash-preview. The committedapps/api/.envsaysanthropicbut that's the LOCAL default — the DO deployment config is the prod source of truth. (Corrects an earlier in-session flag that read.envand worried prod was on Claude.) → the §5 Gemini COGS rate is correct, and the Asian-food advantage IS live. - Asian-food bench evidence (D66): Gemini 3 Flash Preview chosen because
Haiku failed on Asian foods; 6-photo bench cleared Korean gimbap-with-Spam (prior
"salmon" miss) + banchan; "lumping appeared on multi-bowl photos" (strict-decomp
prompt rule added). Breadth beyond Korean/Western dishes UNVALIDATED — spot-test
laksa/cai fan/pho/jjigae/dim sum/bubble tea per launch market.
ai.ts:8comment still says "Gemini 2.5 Flash" (doc drift vs the 3-Flash prod override).
GLP-1 ad-policy constraint (channel-defining)
- Meta: prohibits prescription-drug-implying ads + restricts weight-loss creative.
- TikTok: prohibits weight-management / Rx-adjacent ads; Spark Ads inherit review.
- ⇒ GLP-1 = organic/seeding/ASO/owned-web only. No paid amplification. Paid spend belongs to non-GLP-1 wedges. Verify current platform policy at launch.
Trial-copy debt (verified, already tracked)
- Dead "3 lifetime AI meal scans / no credit card" model still in
PRODUCT.md, flaggedPROGRESS.md:1863; orphanedlogMeal.trial*locale keys. Reconcile before launch.

Competitor Teardown Data (web-checked 2026-06-15)
Pricing/positioning was refreshed again on 2026-06-16. The old shorthand "Trace sits at the top of the band" is too blunt: Trace is expensive versus scan-only and low/mid tracker apps, roughly in-line with MFP Premium, below MFP Premium+, Foodvisor, higher Lifesum IAPs, and far below Noom/coach/clinic programs.
- Trace sits in premium tracker territory, not true top-of-market. The scan alone cannot justify $79.99 because Cal AI and scanner clones anchor scan-only around $20-42/year. The condition-lens interpretation is still the pricing argument.
- Cronometer = the one philosophical neighbor; measurement instrument (84 nutrients, manual targets) vs Trace's interpretation instrument. ~15M users (self-reported). No automated condition lens.
- Calorie-first pack (MFP/Cal AI/Lose It/Lifesum/MacroFactor) = wrong philosophy, but proves photo-scan is a commoditized front door + Cal AI is the GTM lesson (~15M dl, ~$35M ARR; TikTok creator-led + sequenced paid).
- Whitespace (condition-lens + running-totals + no-judgment) = real but narrow: positioning moat not technical; niche-of-niche TAM; distribution (demoing interpretation) is the hard problem.
Competitor Pricing Sweep (web-checked 2026-06-16)
Pricing caveat: many consumer apps A/B test paywalls and expose different IAPs by country, platform, promo, and cohort. Treat these as current public/observed US anchors unless noted, not immutable list prices.
| Competitor | Observed pricing | Source / confidence | Trace read |
|---|---|---|---|
| Trace | $79.99 annual / $9.99 monthly | Product config / internal | Premium tracker price; annual is only 33% off monthly |
| Cal AI | Annual IAPs around $19.99-29.99; monthly/short IAPs around $5.99-19.99; small one-offs visible | Apple App Store IAPs + Cal AI site lacks public price | Dangerous scanner anchor; do not let users compare Trace to scan-only |
| Cals / Nutrivine scanner long-tail | Cals about $34.99 annual / $9.99 monthly; Nutrivine about $41.99 annual / $6.99 monthly | Apple App Store IAPs | Scan-only category clusters below Trace |
| Lose It! | about $39.99 annual; monthly and lifetime vary heavily | Apple App Store IAPs + secondary pricing pages | Budget classic tracker anchor |
| Carb Manager | $3.33/mo billed annually (about $39.96); app IAP monthly about $8.49; annual IAPs vary | Official Premium page + Apple IAPs | Feature-rich tracker can price around $40/yr |
| YAZIO | 12-month IAPs about $23.90-47.90; 3mo about $23.99; semiannual about $34.99; no standard monthly per help docs | Apple App Store IAPs + YAZIO help | Value-priced AI tracker pressure |
| Cronometer | $59.99 annual / $10.99 monthly | Official Gold page | Closest philosophical neighbor, cheaper annual |
| MyNetDiary | Premium about $59.99 annual / $8.99 monthly; Premium Plus/AI observed about $14.99 monthly | Official Premium page + store/pricing references | Tracker incumbent adding AI Coach / GLP-1 from below |
| MacroFactor | $71.99 annual / $11.99 monthly / $47.99 six-month | Official site / press kit | Paid-only body-goal tracker just below Trace |
| MyFitnessPal | Premium $79.99 annual / $19.99 monthly; Premium+ around $99.99 annual | Apple App Store IAPs + official pricing snippets/support | Cleanest premium-tracker comp; Cal AI acquisition raises scan expectations |
| Foodvisor | Observed $83.99 annual and $14.99 monthly, with other IAPs | Apple App Store IAPs; official help says price varies by region/platform | Premium AI nutrition can price just above Trace |
| Lifesum | Observed annual IAPs from about $44.99 to $119.99; 3mo about $29.99-39.99; 6mo about $69.99 | Apple App Store IAPs | Far more variable than the old ~$45 anchor |
| Shotsy | Official comparator says $39.99/year; App Store IAPs show about $39.99-59.99 annual and about $9.99-19.99 monthly | Shotsy official comparison + Apple IAPs | GLP-1 app users may see $79.99 as high unless nutrition value is clear |
| MeAgain | about $79.99/year | Shotsy official comparison page, not independent | GLP-1 premium dose/companion anchor similar to Trace annual |
| Noom Weight / Noom Med | Weight: $70 monthly or about $209 annual; Med/GLP-1 programs starting about $99-129+/mo before medication nuance | Official Noom pricing/support/Med pages | Upper anchor, but includes behavior program and medication adjacency |
| Simple | Pricing opaque/dynamic; observed IAPs around $29.99 quarterly and $39.99-49.99 annual | App Store/Sensor Tower style IAP data; low confidence | Do not overuse as price comp without fresh device/paywall capture |
| Healthify | Official HealthifySmart 3mo offer Rs 2,399; third-party sources cite broad Pro/coach ladders | Official plan page + third-party breakdown | India/APAC pricing must be localized; coach tiers can be high but app tiers differ |
Annual discount math:
| App | Monthly x12 | Annual | Annual discount |
|---|---|---|---|
| Trace | $119.88 | $79.99 | 33% |
| Cronometer | $131.88 | $59.99 | ~55% |
| MacroFactor | $143.88 | $71.99 | ~50% |
| MyFitnessPal Premium | $239.88 | $79.99 | ~67% |
| Foodvisor | $179.88 | $83.99 | ~53% |
| Shotsy | $119.88 | $39.99 | ~67% |
Pricing takeaways:
- Trace's annual plan is not crazy in the premium-tracker frame, but it is very expensive in the scanner frame.
- The current annual discount is weaker than many subscription competitors. If annual conversion is soft, test either $14.99 monthly with $79.99 annual or $9.99 monthly with a $69.99 annual.
- MFP Premium+ and Foodvisor are the best "premium tracker" anchors; Noom is an upper-category anchor, not a direct self-serve tracker comp.
- The free GLP-1 companion is a good acquisition wedge, but Shotsy pricing means GLP-1-specific users may not expect to pay $79.99 unless paid nutrition value is explicit.
- APAC needs separate pricing logic. RevenueCat 2026 shows IN/SEA Google Play yearly medians around $14.64 and IN/SEA first-year payer LTV at the low end; Singapore/Korea can be premium tests, but Vietnam/India cannot inherit the US paywall assumption.

GLP-1 Field Data (web-checked 2026-06-15)
- Shotsy — direct precedent for free-wedge→paid; ~100K dl (measured; its "1M+" is self-reported, unreliable). Paywalls the level curves Trace gives FREE; upsells dose tracking, not nutrition → Trace's nutrition bridge is differentiated.
- Noom — the one to watch: GLP-1 Companion + protein logging + Muscle Defense™; but weight-loss-framed, coaching-heavy, and priced as a behavior/medication- adjacent program: Noom Weight is roughly $70 monthly or ~$209 annual; Noom Med/GLP-1 programs start around $99-129+/mo depending plan/medication nuance.
- Caloria — closest philosophical match (endocrinologist-built, metabolic steadiness) but ~20K dl (self-reported).
- Telehealth-bundled (Embla ~€150/mo+Rx · Voy £94–239/mo · Found $349–699/mo) = app is a retention wrapper around a prescription; different business.
- "Nutrition steadiness on GLP-1, interpreted, non-weight-loss" = genuinely open lane; Noom is the credible mover toward it.
- TAM: anchor on ~25–30M US adults who've tried GLP-1 (KFF-derived). No credible GLP-1-app market size exists; reject vendor "$Xbn / 280M users" figures (those reports measure supplements, not software).
Ad-policy (the organic-only thesis — confirmed + worse)
- Meta: Rx weight-loss ads need prior written permission + geo-restriction (Health & Wellness ad standard); 35-state-AG coalition (Dec 2025) pushing tighter.
- TikTok: prohibits weight-management / Rx ads; bans "GLP" in product branding; Spark Ads inherit review.
- NEW + load-bearing: TikTok May 2026 guidelines suppress weight-loss- medication content ORGANICALLY, not just paid → GLP-1 is doubly constrained. Frame GLP-1 around nutrition/protein/companion, never weight loss.
- Nuance: Trace advertises a free nutrition companion, not a drug — a nutrition-steadiness ad that never names the med/weight-loss may clear review; worth a small policy-probe, don't bet the launch on it.
GTM Benchmarks (web-checked 2026-06-15)
- Creator seeding: gift+affiliate (no upfront) converts nano/micro only; Cal AI
ran 150+ retained creators ~4 posts/mo (the paid version). UGC $150–300/asset;
health affiliate 5–30%; paid CPI N.America $2.50–5.00. FTC
#admandatory, enforcement up on small creators 2025–26; brief experience not outcomes. - ASO: condition nouns OK; verbs (manage/lower/diagnose) trip Apple 1.4.1; Google requires "not a medical device / consult a professional" disclaimer. NEVER drug brand names in metadata (Apple 5.2.1; Novo 130+ suits 2025) — use "GLP-1". Screenshots = top free lever (+9pp); store-metadata localization +26–30% (Trace already has in-app locales); CPP +156% on referred traffic (AppTweak sober +5.9–8.6%) — needs inbound; ASA popularity = free keyword tool.
- Web-to-app: H&F top performers 23%+ download-to-trial; Noom quiz = 113 screens, email gate ~33%, quiz IS the demo. Trace's free sample-demo is a cheaper show-don't-tell alternative — don't blindly copy Noom.
- Lifecycle: 55% of 3-day cancels Day 0; 82% of H&F trials start on download day; push+in-app carry it, email secondary (open ~48%/click ~1.5%); pause>cancel; 95% of annual cancellers never return → one win-back email only; ~5-min TTV rule.
- Referral: two-sided give-get (91% of successful programs); WhatsApp+SMS ~90% of sharing; mature 20–35% of installs, referred +37% D30 — but compounds AFTER a base; free month > cash.
- SEO: Trace's 976×12 data is a programmatic moat BUT YMYL needs a credentialed (RD/MD) reviewer byline (Sept 2025 update penalized missing author creds); ~30–40% of permutations have volume; 12–24 mo to mature; organic CAC ~3× < paid once mature.
- Highest-EV experiment: test 5–9 day trial (≈+10–15 pts trial-to-paid).

Known gaps (next pass)
- No clean public quiz-step visit→install→trial benchmark.
- No sourced health-app-specific organic-vs-paid dollar CAC (only the ~3× ratio).
- KFF GLP-1 user figure cited via aggregator — cite KFF primary directly.
- Non-AI infra cost/MAU still an estimate — pull real numbers for the §5.2 COGS line.
Open Questions For Draft
- Which first launch wedge gives Trace the best blend of pain intensity, creator ecosystem, low claims risk, and paid conversion potential?
- Is "GLP-1 nutrition companion" the best acquisition wedge, or should the free GLP-1 companion remain a lead magnet while paid nutrition is positioned more broadly? (Sharpened: GLP-1 is free forever — what is the explicit bridge from free companion to paid food-logging, and how is it measured?)
- How aggressive can Trace be with hard paywalling when the core food logging path is Pro-gated, without suppressing first value too early? (Note: the free sample-meal demo already provides pre-paywall proof; the real test is a "few free real scans" variant, which COGS makes economically free to run.)
- What CAC threshold is sane before six-month retention is known? (Derived: ≤ $20–25 payer CAC target; the binding unknown is renewal, not cost.)
- What is the platform launch order (Android-first per project notes?) and the geo/language scope, given 5 shipped locales incl. VI?
- Remaining pricing gap: capture live in-app paywalls by device/region for Cal AI, Simple, Lifesum, Foodvisor, MyNetDiary Premium Plus, and local APAC competitors; public IAP lists do not reveal cohort-specific paywall sequencing or trial copy.
