About

TreadLog

Features
Read full description

TreadLog quietly records the running habit you build on the treadmill. There are plenty of outdoor GPS running apps, but few made for people who run on a gym treadmill. TreadLog focuses on indoor treadmill running only. When your workout ends, just snap a photo of the console. It reads your distance, time, calories, incline, and speed and fills in a log card for you. OCR auto-fill from a console photo Photograph your treadmill console and TreadLog recognizes the on-screen numbers (distance, time, calories, incline, speed) to fill the entry automatically. Recognition runs entirely on your device. If anything is misread, fix it right there in a tap. Quick manual entry too No photo? Just type in distance and time and you're done. You can add outdoor runs by hand as well โ€” fast and lightweight. Calendar heatmap See when and how much you ran at a glance. The more you ran on a day, the deeper the color, so your monthly pattern jumps out instantly. A monthly summary of runs, distance, and time is included too. Streaks Watch your consecutive running days add up and keep the momentum going. Missed a day? That's okay โ€” just start again. Stats & pace trend View your all-time cumulative distance, time, and run count, and see how your pace is improving on a trend chart. A weekly distance graph and a weekly goal keep this week's progress in check. Light & dark themes Follow the system setting or pick light or dark yourself, so early-morning or late-night sessions stay easy on the eyes. Your data stays on your phone No sign-up, no login, no server. Every record is stored only on your device. Switching phones? Back up with .zip export and import. A light, quiet treadmill running journal โ€” manage your indoor running and cardio logs cleanly with TreadLog, and take today's step.
