【 What set is this? How long have I rested? How many sets and how much weight did I do last week? 】 【 I can't remember at all! 】 That's why I built HotTrain. I tried using my phone's notes — too messy. Scrolling through history was even worse. So I just wrote an app myself. For me, and for anyone who needs the same thing. It's not a workout video app. It doesn't push training content to you. And no ads. It does one thing: helps you log your training, clearly and simply. 【 How to use it? 】 Create a plan. "Chest Day", "Back Day", "Leg Day" — whatever you want. Add exercises: dumbbell bench press, squats, deadlifts — anything goes. Log each exercise with sets, reps, weight, and muscle group. So you can check your volume later. On training day, open the plan, tap Start Workout, and log set by set. Rest timer counts down between sets. It alerts you when time's up. No need to watch the clock. When you're done, it shows total workout duration and total rest time. Every exercise has its own history. Tap to see the curves: weight, sets, reps. Going up? Making progress? See it at a glance. 【 Training status, clear at a glance 】 Calendar page: which days you trained, which days you skipped, which days you didn't finish. Stats page: completion rate by month, year, or cumulative. Summary page: total training hours, trend over time. Flip through them, and you'll know exactly where you stand. 【 A few extra tools 】 Stopwatch & countdown timer — use them during workouts Swap plans on the fly — don't feel like today's plan? Switch to another day's Body metrics — track weight, body fat %, BMI Multiple themes — change the look anytime Cloud backup — switch devices without losing data Share plans — generate a code, friends paste it and import Data stays local. Cloud backup is optional. No upload, no loss. If you train on your own and want to train smarter, give it a try.
