Update Triggers Backlash

Lead
MyFitnessPal, Inc. shipped version 26.15.0 on April 14, 2026, altering the meal logging interface. The update introduced critical bugs that erase meal entries and freeze onboarding.

Live Update Interface

Release Summary
According to official release notes, version 26.15.0 focused on streamlining the core meal logging interface, introducing a new "Today" tab and an AI-powered Coach. The publisher eliminated "the extra checkmark tap when adjusting serving size in My Meals" so that calorie and macronutrient totals would "update live".

The update also included a specific bug fix for iPad users.
[6] Prior to this release, the application would unexpectedly close when individuals attempted to edit a Premium+ meal plan containing custom macro targets.

Erased Meals and Freezes

Breaking Changes
The new interface broke core functionality across the platform. Users are experiencing critical bugs where meal entries are erased upon returning to the main screen, directly correlating with the altered UI.

App Store reviews confirm a separate bug that prevents new users from completing the onboarding process by freezing at the country selection screen.

Users on r/Myfitnesspal describe severe historical data loss linked to the update, with threads documenting years of missing progress.

Rating Drop and Backlash

User Reception
The update caused the average star rating in reviews to fall by 0.86 stars, with reviews for v26.15.0 averaging 3.24 stars against 4.1 for v26.14.0. Prior to the release, reviewers praised the platform as a "disciplined way of tracking food intake". Post-update reviews document severe functional regressions.

As one 1-star reviewer on v26.15.0 stated, "I can’t seem to add more than two items to any given meal, or when I add them and then I back up to the main screen it erases them." Users also suspect the publisher of padding the score, with a 1-star review citing "HORRIBLE update & FAKE reviews" amid an influx of nonsensical positive ratings.

Quiet Weight Hotfix

Release Cadence
Following the initial backlash, the publisher quickly shipped version 26.16.0 on April 21, 2026. This subsequent release aimed to address "bugs related to the weight logging experience" and fix loading delays associated with the weight graph.

The swift rollout of v26.16.0 appears to validate the historical data loss complaints reported by long-term users.
[4] The engineering pattern points to a suspected database migration error that temporarily corrupted user profiles during the v26.15.0 rollout, forcing the publisher to issue a targeted patch.

Premium Subscription Pivot

Strategic Context
The sweeping interface overhaul appears designed to justify the platform's $19.99/month Premium subscription tier. By introducing flagship features like the AI-powered Coach and the redesigned Today tab, the publisher likely aims to reposition the app as a comprehensive digital health ecosystem rather than a simple calorie tracker.

Trust and Revenue Risks

Expert Verdict
With nearly 960,000 monthly downloads in the US iOS market, the blast radius of these bugs is massive. The inability for new users to bypass the country selection screen directly halts user acquisition at the top of the funnel.

The publisher will likely need to issue further emergency hotfixes to fully resolve the meal-saving bug. If the core logging functionality remains unstable, MyFitnessPal is likely to see a noticeable dip in active users and Premium subscription revenue by the end of Q2 2026. These figures compare the 250 US App Store reviews tagged with v26.14.0 against the 99 tagged with v26.15.0, measured on 2026-04-24.
