MyFitnessPal: Calorie Counter v26.15.0 causes data loss and entry bugs, April 2026

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.

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.

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.

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.

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.

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.
