FiveByFive
The classic 5×5 barbell program, tracked with nothing you don’t need.
In development(01) Overview
FiveByFive keeps a proven strength routine honest: two alternating workouts, five sets of five, and a weight that climbs a little each session. The screen shows the lift in front of you and gets out of the way.
It runs entirely on your phone. Sign in only if you want your history to follow you to another device — until then, nothing leaves the handset.
(02) What it does
Tap-to-log sets
Set circles start blank; tap to record each set, counting down from five when you miss a rep.
Automatic progression
Add weight after a clean session, with a measured 10% deload after three failed attempts.
Built-in rest timer
A three-minute timer runs between sets with a quiet chime, so you keep your pace without watching the clock.
Progress charts
Per-lift weight history with your starting number, current working weight, and total gained.
Four quiet themes
Midnight, Crimson, Forest, and Paper — legible in the gym, easy on the eyes at home.
Optional cloud sync
Apple, Google, or email sign-in keeps your log in step across devices. Entirely opt-in.
