我们打造 sTrain 是因为我们尝试过的每一款训练 App 都想取代我们的训练计划。但这一款不会。它只想成为你在组间休息时随手记录的笔记本。
§ 01What it is
sTrain is a workout log. You pick a built-in template or write your own. You type an exercise, a weight, a rep count, and duplicate the row for another set. You check it off when you’re done. Everything stays in a SQLite file on your phone — no account, no cloud, no sync.
§ 02What it does
Sets, reps, weight, cardio, and timed work. Static templates for Push/Pull/Legs, Upper/Lower, and 4-Day Strength. An inline rest timer with a haptic buzz. Statistics — count, streak, weekly average, total time, volume PRs. A full JSON backup whenever you want it.
Your body is not a dataset. It’s a thing you’re living in.
§ 03What it won’t do
No program that adapts. No coach. No periodization, no deload weeks, no progression engine. No 1RM calculator. No plate-loading screen. No leaderboards, no social feed, no gamification. The PRs are honest volume — max weight × reps, nothing extrapolated.
§ 04Who it’s for
People who already have a training plan — whether they wrote it themselves, got it from a coach, or bought it as a PDF — and need a clean place to log. People who want a quiet log on their own phone, not a social network for workouts.
