About

TreadLog

Features

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.
