liftmate is the name I build software under. The first product is Workout Logs — logging a set faster than the notebook in your gym bag, in Vietnamese, without taking your training data anywhere.
Android 8.0+ · No account · No ads
An Android app for writing down what you just lifted: which exercise, how much, how many sets and reps. Then next week you open it and know exactly which number to beat.
Enough for a Vietnamese gym: machines, cables, barbells, dumbbells, bands, and bodyweight work too. Every exercise has step-by-step instructions, common mistakes and a tip — written from scratch, not machine translated. Search works without diacritics or with local slang, and anything missing you can add yourself.
Open an exercise and the app already shows “Last time” — what you lifted in your previous session, and for how many reps. With the numbers already there, most sets take a single tap to log, and the rest timer starts on its own. The real competitor here is a notebook and a pen.
No account, no sign-in, no loading screen — open it and log, weak signal or none at all. Your log lives on your phone, exports to a file whenever you want, and the app reminds you every two weeks if you forget. Only the exercise illustrations need downloading the first time.
No cap on sessions, no counting exercises, no ads interrupting your workout. Recording your own training is not something to put behind a paywall — if there is ever a paid tier, it sells deeper analysis, not the right to log.
Animation, muscles worked, suggested rest, step-by-step technique
Weekly volume, turned into something easier to picture than kilograms
Not a statement of intent — in this version the app simply has no path to send your training log to a server. No account, no sign-in, no cloud sync.
The app does call my server, but only to pull exercises and illustrations down to your phone. There is no way back up: there is nowhere over there to keep your sessions. No account, no cookie, nothing that can recognise your phone.
The stats switch starts in the off position — you don't have to go hunting for it, and it isn't rolled into the consent button on first launch. Leaving it off costs you nothing. Change your mind later and it stops the moment you flip it in Settings.
Export everything to a JSON file — free, as often as you like. New phone, or a different app entirely: your data goes with you. Want out? There's a wipe button in Settings, or just uninstall — no need to ask me, because I don't keep a copy.
liftmate is the name I publish software under. Behind it is one person: Vu Duc Duong, working in Vietnam.
Workout Logs exists because I couldn't find a training log that both spoke Vietnamese properly and didn't require an account just to take my own training history elsewhere.
