iPhone
Log your squat, bench and deadlift maxes and watch the numbers climb. Link the supplements you take to the same timeline and see what's working. All free right now.
BIG3 Tracker logs the three lifts that matter — squat, bench press and deadlift — and turns them into a picture of how your strength is actually moving. What makes it different: you can log the supplements you're taking on the same timeline, so you can see which stretches of progress line up with what you were on.
WHO IT'S FOR
- Lifters chasing a bigger squat, bench and deadlift
- Anyone who wants progress in numbers and charts, not vibes
- People taking supplements who aren't sure whether they're doing anything
- Anyone who has started a training notebook and quietly abandoned it
WHAT YOU GET
Log the big three
Record weight x reps for squat, bench and deadlift. Estimated 1RM is calculated for you. Accessory lifts are covered too — around 100 exercises across chest, back, shoulders, arms, legs and core.
See your progress
Line charts for each of the three lifts, plus your SBD total. Swipe a chart sideways for a month-by-month best. Month-over-month change is worked out automatically.
Personal bests, celebrated
Beat your total and the app makes a thing of it — which lift went up, and by how much. Share the result as an image if you want to.
Supplements on the same timeline
The periods you were taking each supplement are drawn over your strength charts, so patterns are easy to spot.

A NOTE

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Charts and reminders got a big upgrade.
• New "By exercise" chart: pick a body part and exercise to see any lift's progress, color-coded by rep count (1–20 reps). Accessory work included
• Swipe sideways for a month-by-month max table, broken down by rep count
• Sets that beat your best at that rep count now get a MAX badge as you log them
• New reminders: a nudge on the days and time you choose, plus a gentle one if you've been away. Set them up in the Profile tab
• Plus some small fixes
