Markdown — pastes cleanly into Claude, Notion, anywhere.
Two principles that win it.
Locked dashboard, always
Day-one calorie and workout summary visible without drilling — the exact screen MFP destroyed in its 2026 redesign.
Flat price, no ratchet
One price buys all core features forever; never move a working feature behind a new paywall tier.

Shape, not volume — these are ordered, never counted, and the trend is Google’s relative interest index, so it reads direction and not size. Weeks still filling are excluded. Audiences are what Apple and Google complete after “fitness tracking apps for”, with the query stripped and platform or price modifiers dropped. Comparisons are completions of a competitor’s own name. Trend captured Aug 24, 2026. Store hints captured Aug 25, 2026.

People pay here, but billing draws less anger than typical. The friction is somewhere else.
“I’ve been using MFP for over 10 years and had little to no issues. With the newest update, I have seriously considered switching to a different calorie counting app. It’s much more difficult now to actually see a calorie breakdown or log foods properly. Please let us go back to the OG layout in settings or something!!”
Every app owns part of it. None owns the gap.
UX complaints run 10% of complaints here vs 2.9% everywhere else — and no one has fixed it.
At or below typical — table stakes, not where you win.
Bars compare each theme’s share here with a typical app’s. The words have fixed cutoffs: elevated from 1.15, high from 2, extreme from 3.5 times typical.

The wedge, scoped to what you ship next.
- Single-screen daily summary: calories + key lifts at a glance, zero drill-required
- Reliable Apple Watch / Health sync — tested before every release
- Flat-price paywall: one purchase, all features, stated clearly on first launch
- Persistent food log with barcode scan free forever — never gate it
- No dark-pattern trial: cancellation one tap, same surface as sign-up
- Offline-first data entry — log a meal or set without a network round-trip
- Post-launch UI overhauls that relocate core diary views
- Splitting one feature across free/premium tiers after users depend on it
- Auto-renewing trials that charge before the user notices
- Ad interstitials or pop-up upsells mid-workout
- Watch app that requires separate login from phone app
- AI food-photo recognition shipped before hallucination rate is acceptable
Each claim maps to a verbatim review.
High on UX/paywall demand; unproven on acquisition away from MFP's 2.3M-rating gravity
“I used this app for over four years before the most recent update and never had a problem. Then they made it “better”. It’s awful now, my reset timers get messed up doesn’t save nearly every workout. The Apple Watch feature does not sync well and over complicates the entire process. Stick to what you did well Strong.”
“Charged my credit card to extend the trial period. I asked for a refund the same day. I explained that I did not like the app and its function. They refused and charged full price for a basic, unimpressive app. I think at minimum a partial credit should have been issued. Find a better fitness app. Weak scammers.”
“What a shame. I have had Strava for like 4 years now. Looked forward to the year in review. Now you have to pay to see it. Sad. The app has been hiding more and more behind paywalls. Garmin gives me all the stats that Strava makes you pays for so no need to burn $80. Just a shame I can’t see my “Year in Sport” anymore.”
Assumptions most likely to sink it.
Hevy already holds the low-anger gym-log slot (2% negative, 85k ratings) with IAP up to $74.99 — direct collision risks a crowded landing
Churning MFP users will pay a flat fee rather than use a free alternative
Offer a paid early-access build ($X flat, no trial) to MFP-refugee communities; measure actual purchase rate, not signups
Low purchase conversion → narrow to free-with-optional-tip or shift to a B2B trainer-facing model
Stable sync across Watch, Health, and third-party devices is achievable at launch quality
Once a minimal version ships, track sync-failure rate in crash/analytics logs across device matrix for 30 days
Persistent sync failures → descope Watch and third-party sync to v2; ship phone-only first
A combined nutrition + gym-log app out-retains two separate best-of-breed apps
Measure 60-day retention split between users who log both food and workouts vs. single-mode users post-launch
Single-mode users dominate → position as gym-log only (compete directly with Hevy/Strong) and drop nutrition scope
Hevy's low-anger gym-log slot is not already a ceiling for new entrants in this sub-niche
Run paid-acquisition test targeting 'Hevy alternative' and 'Strong alternative' keywords; measure install-to-log rate vs. cost
CAC unsustainable against Hevy's 85k-rating moat → differentiate on nutrition integration MFP users need, not gym-log parity
Paid early-access conversion rate among self-identified MFP churners falls near zero — meaning users defect to free apps, not paid alternatives, and the flat-price model has no viable floor.
- UX complaints run 3.44× the corpus norm across 10 of 13 apps — the widest elevated gap
- Sync/data failures elevated 3.35× norm, present in all 13 apps — no incumbent has solved it
- MFP's 71% negative rate on 974 sampled reviews signals mass exodus from the dominant player
- Hevy's 2% negative rate proves a calm gym-log experience is achievable and monetizable at IAP up to $74.99
- Share of MFP refugees willing to pay a flat fee rather than find a free substitute is unverified
- Acquisition cost to intercept churning MFP users at scale is unknown
- Whether combined nutrition + workout in one stable app beats two best-of-breed apps is a product bet
