Most apps show a calorie burn (TDEE) that's just a generic estimate from your age, height and weight. GymDiary is different: it measures YOUR real daily burn from your actual weight trend and meal logs — a number that's truly yours and adapts as your body does. Now you can finally see why the scale stalls. • Stats improvements and a cleaner layout • Minor bug fixes and stability improvements Thanks for using GymDiary! ### 2.3.1 — 2026-07-05 Thank you for using Gym Diary — and for telling us what you wanted next. This update is built around the features you asked for. ■ Lock Screen Live Activity (New) "I want to keep my streak going, but life gets busy and I forget." We heard this a lot — so we did something about it. Your streak now lives right on your Lock Screen and in the Dynamic Island. No need to open the app — a quick glance tells you exactly where today stands. ・Haven't logged today? You'll see a countdown to the deadline (3 AM daily), so "about to break your streak" is impossible to miss. ・Your AI trainer speaks up in the moment — a gentle nudge some days, a firm kick on others. ・The second you log, it flips to "Done for today." Little wins, stacking up. ・Tap it to jump straight to logging. Catch the motivation the moment it strikes. ■ A heads-up from your AI — before your streak slips Another one straight from your feedback: "I looked up and my streak was already gone." Now, if the deadline is near and you still haven't logged, your AI trainer reaches out with a reminder. You don't have to make the first move — your AI does. ■ A new way to start: a real conversation with your AI trainer You told us the initial setup felt cold and mechanical. So we rebuilt it. Now you chat with your trainer to shape the goals and plan that fit you — and you feel like you have a coach in your corner from the very first tap. ■ A Home screen redesigned around "keeping it up" The screen you open every day now puts your streak front and center. See "done today / not yet" at a glance, with logging just a tap away. The proof that you're sticking with it, pushing you forward daily. ■ More improvements ・Refined visuals for a cleaner, clearer look ・Various bug fixes for a smoother experience We'll keep shaping Gym Diary together, with your voice leading the way. Got an idea, or something that bugs you? Tell us anytime through the app or a review — your words become our next update. Now, today's first rep.
