Show up, do today's session, watch your lifts climb. A forgiving weekly streak that survives rest days and bad weeks — so you keep going instead of giving up.
Build Momentum is the gym tracker for people who start strong and then drop off. It does two things brilliantly:
IT PICKS TODAY'S WORKOUT FOR YOU.
Open the app and there's one session ready to go, no decision fatigue, no scrolling a thousand exercises. Tap Start and log a set in two taps. Weights and reps pre-fill from last time.
A STREAK YOU CAN'T BREAK.
Most apps punish you for missing a day. Build Momentum counts by the WEEK, so rest days never hurt you, and a "freeze" protects your streak through a missed week.
WATCH THE NUMBERS GO UP
Automatic personal-record detection with a celebration when you beat a best
Per-lift strength trends (top set and estimated 1RM)
Weekly training volume vs last week
BUILT TO BE FAST AND PRIVATE
Works fully offline, perfect for gyms with no signal
Every set saves instantly; a crash never loses your work
Your data is encrypted on your device and never leaves it
Export everything to CSV any time, it's your training history
Ready-made routines (Full Body, Push/Pull/Legs, Upper/Lower) plus a built-in editor to make your own. Around 30 common lifts included, and you can add your own.
No account. No ads. No tracking. Just show up and get stronger.
