Your camera counts your reps. Every set becomes a short timelapse with a live rep counter baked in — ready to post. Take on Day100, Murph, or build your own challenge.
Do the reps. Get the video. Post it.
DAY100 turns your phone into a rep-counting camera. Prop it up, start your set, and the app counts your squats, push-ups, and pull-ups automatically using on-device motion tracking — no wearables, no tapping, no manual logging. Every set is recorded, and when your day is done, DAY100 stitches the footage into a short, sped-up timelapse with a live rep counter overlaid on top. Ready to post, straight to your instagram or tiktok.
COUNTS YOUR REPS FOR YOU
Set your phone down and just work out. DAY100 watches your form through the camera and counts each rep in real time, with audio cues so you never have to look at the screen. Squats, push-ups, and pull-ups — each with its own smart detection tuned to how you actually train.
EVERY SET, RECORDED
Each session is captured on video with your rep count tracked frame by frame. No dead footage — DAY100 trims to the action automatically.
ONE TAP TO A SHARE-READY TIMELAPSE
At the end of the day, your sets are stitched into a single short timelapse: sped-up footage, a slick animated rep counter and progress bar, a cinematic slow-down on your final rep, and a completion card with your stats. Customize the look — size, position, colors, glow, mirror, speed — with a live preview that matches the final video exactly. Then save it or share it anywhere.
PRIVACY BUILT IN
Want to post without showing your face? Turn on face hiding and DAY100 automatically blurs or pixelates faces throughout the whole clip. Everything — rep counting, video, your history — stays on your device. No account required.
CHALLENGES THAT KEEP YOU HONEST
Take on built-in challenges like "DAY100" — 100 days, 5,000 reps, three strikes and you're out — or quick one-day tests like Triple 10 and Murph. Miss days and you lose. Finish and you get the receipts: a full record of every day, every rep, every video.
MAKE IT YOURS
Create your own challenge — pick the exercises, the daily goals, the duration — and share it with friends so you're all grinding toward the same finish line.
WHY IT WORKS
Logging reps is boring. Posting proof isn't. DAY100 makes the receipt automatic: every workout produces a video you'll actually want to share, and every share keeps you accountable for tomorrow.
Do the work. DAY100 handles the evidence.
