A gym app built around the red start button. Plan the session, hit the timer, log the real sets, and watch weight and body fat move — without turning training into admin.

the timer
Delts treats the red start button as the source of truth. Add workouts, start the timer, log the work, and keep the rest quiet.
01
Daily workout board
Build today from the exercise library, saved workouts, or copied days. Cards show sets, reps, RPE, and muscle/equipment context at a glance.
02
Workout timer
The main red timer starts and ends the workout, drives session timing, and supports a focused Live Activity timer on iPhone.
03
Set, rep & RPE logging
Log reps and effort only while the workout is active, with support for strength RPE and CR10-style effort tracking.
04
Exercise library
Browse exercises by target muscles, equipment, level, and split. Detail pages keep the image pinned while instructions scroll.
05
Progress charts
Track weight and body fat across week, month, 3M, 6M, 1Y, and all-time, with visible grid lines, averages, net change, and goals.
06
Apple Health sync
Optional HealthKit access can import and save body weight and body fat logs when you grant permission.
07
Body composition pickers
Choose exact body fat numbers or visual ranges, with separate preferences for current and goal body fat.
08
Personalized setup
Set height, weight, training goal, target muscles, issues, frequency, duration range, split, equipment, and optional 1RM anchors.
09
Custom themes & icons
Switch between Lime, Cyan, Pink, Amber, and Violet. The app tint and Home Screen icon change from one setting.

01
Start the session
The red button records start and end time. Editing set data is tied to an active timer, so planned workouts stay separate from performed work.
02
Log what you did
Add sets, reps, and RPE inline while the timer runs. The board shows live totals as the session builds.
03
Review the trend
Weight and body fat charts use a visible grid, four x-axis dates per range, and year labels when long ranges cross years.
04
Make it yours
Theme color and app icon stay matched, with real icon previews in Settings. Copy a previous day to start a session fast.
