What's New in Trn.ai
2.2
October 3, 2026
• Workout chat: talk to your coach mid-session about form, soreness or fatigue — your main chat stays clean. • A smarter coach: it remembers the conversation and won't start or end a workout because of a passing remark. Start new workouts from the "+" menu. • Suggested working weight for every exercise, based on your past sessions. • Type weight and reps straight from the keyboard. • Finished exercises fold away and the next one scrolls into view. • New workout menu: add an exercise, build a superset, finish. • Supersets: shared sets × reps for the whole group, plus suggestions for good pairs. • Mark an exercise "don't suggest" and the coach will leave it out. You can also share exercises. • Warm-up hint: no need to log it as a set. • No more being signed out in the middle of a workout. • Exercise guides in Russian, plus smaller UI polish.

FAQ
How does Trn.ai create workouts?
Trn.ai acts as a strength coach that you talk to. You describe your desired workout, such as 'legs today, my knee is cranky,' and the coach generates the session, sets targets, and provides guidance.
Is Trn.ai suitable for use on the gym floor?
Yes, the workout screen is designed to be used with one hand. It clearly lays out warm-up ramps, target reps, and rest times, and logging a set requires just one tap.
Does Trn.ai track my progress automatically?
The app remembers every session, including weight, reps, and the date. Progress charts are automatically generated from your actual lifted weights, and personal records are noticed and saved without manual input.
How does Trn.ai integrate with Apple Health?
Finished workouts are sent to Apple Health with their start time, duration, and an estimated active energy burn. This data transfer is one-way, from the device to Health, and your training data is not shared elsewhere.
What languages does Trn.ai support?
The coach answers in your language, and the app is translated to match. Supported languages include English, Spanish, German, French, and Russian, with properly written translations.
What are the subscription options for Trn.ai?
Trn.ai offers a free tier with a daily allowance of coach messages. Premium access, available monthly for $2.99 or yearly for $29.99, substantially increases this allowance for users who communicate with their coach frequently.
Does Trn.ai have ads?
No, Trn.ai does not contain advertisements. The app is ad-free, focusing on providing a seamless user experience for its fitness tracking and coaching features.
How do I get support if I have an issue with Trn.ai?
Support is available through a real conversation directly within the app. Human representatives answer questions about your plan or any issues you might encounter.
