100 Day Fit is your personal bodyweight fitness coach. Pick your exercises, take a quick fitness assessment, and the app builds a personalized 100-day program that grows with you — increasing your goals each week based on your feedback.

EIGHT BODYWEIGHT EXERCISES Choose from push-ups, squats, planks, pull-ups, bar hangs, and burpees. No gym or equipment required — just you and your phone.

THREE WAYS TO TRACK • Guided Mode — The app paces you through every rep with audio cues, countdowns, and timed rest periods between exercises. • AI Mode — Place your phone on the ground or prop it up nearby and let the app count your reps automatically using your camera. Available for all six exercises. • Manual Mode — Work out at your own pace and log your results when you're done.

SMART WEEKLY PROGRESSION At the end of each week, 100 Day Fit celebrates your progress and asks how you felt. Tell it the workout felt good and your goals increase automatically. Found it too hard? Your goals stay the same until you're ready. You're always in control.
