Latest release

Streaks, achievements, and the trends behind them.

The newest Trainerrr release keeps count for you: a weekly streak, achievements for real milestones, and an Insights screen that shows how your weight, food, and training change over time.

Six Trainerrr screens showing calorie tracking, an active bench press workout, weekly activity, daily nutrition, workout history, and training notes
One app for the plan, the session, the meal, and the review.

STREAKS AND ACHIEVEMENTS

Every week you train counts.

A week with at least one workout adds to your streak, however many you planned. Log through ChatGPT or Claude and the reply tells you when you beat your last top set or close a ring. Every four weeks in a row earns a freeze, and a saved freeze covers a quiet week.

NEW HOME

Today and this week on one screen.

Steps and workouts for today, then training minutes and active days for the week, with a 12-week activity map underneath. Days without data stay blank. They never count as zero.

INSIGHTS

See the trend, not just today.

Weight, food calories, protein, and training time over 7 days, 4 weeks, or 12 weeks. Open it from Home or the Journal.

OFFICIAL CHATGPT APP

Tell ChatGPT what you ate or lifted.

Connect Trainerrr in ChatGPT, then use natural language to build plans, log meals and workouts, or review your own fitness data. Other compatible assistants can connect through MCP.

Keep the context that makes the log useful.

Sets and reps do not explain everything. Food logs, training notes, body check-ins, and activity add context to your workout history.

Nutrition

Log the meal. Reuse what you eat often.

Search foods, scan barcodes, save meals, or enter the missing item yourself.

See nutrition → Journal

Keep the cue that worked.

Save training notes and weekly photo check-ins beside your history.

See journal → Health

Connect only what you choose.

You choose which Apple Health or Health Connect categories to enable on each device.

See health connections → Optional AI
