GainEngine tells you what to lift and how much, then raises the weight when you are ready. It plans your strength training so you can open the app and get to work. Most gym apps only log what you did. GainEngine plans what you do next. After every session it adjusts your weights based on your progress, using progressive overload, so you keep training at the right intensity to build strength and muscle. There are no spreadsheets to maintain and no complicated programs to decode. You don't have to wonder whether today is the day to add weight. The app works that out for you. What GainEngine does: It tells you what to train in each session. It tells you what weight to use for each lift. It tells you when it is time to increase the load. It automates progressive overload from session to session. It tracks your long-term progress and your personal records. It keeps your training clear and consistent. Who it is for: GainEngine suits anyone doing gym workouts, weightlifting or strength training who wants steady progress without planning every set by hand. It works whether your goal is getting stronger, building muscle or simply training consistently. GainEngine Plus: A GainEngine Plus subscription unlocks full progress charts, personal records, body measurements, the AI Coach and unlimited workout days.

kach is an iPhone gym tracker: log every set on your phone, or run the entire workout from Apple Watch without the phone. Follow the session from the lock screen with a Live Activity. kach then suggests your next weight and reps from your history: more when you hit the top of your range, a lighter reset when you stall. Every number is a suggestion you can change. No account, no subscription, works offline. Your training stays on your phone.
