About

UdeTancho

Features
Read full description

UdeTancho is a Japanese-inspired fitness app that automatically counts push-ups and quietly records your daily practice. Place your iPhone on the floor. The front camera reads the movement of your face in real time and counts your push-ups, so you can focus on the movement instead of tapping the screen or counting by hand. β–  Waka Progress As you train, Hyakunin Isshu poems are written one character at a time. Completed poems unlock a modern translation, commentary, and historical background. Your workout record gradually becomes a poetry collection. β–  Poetic Places Map Explore places connected to the poems. Follow poetic place names and the poets' historical centers while the world of Hyakunin Isshu opens up little by little. β–  Records See today's reps, total reps, streaks, and history at a glance. A heatmap makes your practice visible over time. Even small sessions matter when they add up. β–  Built for Sustainable Practice If you leave the measurement screen or if no count is detected for a while, measurement stops automatically. UdeTancho is designed to support a sustainable habit, not unsafe max-rep chasing. β–  Key Features β€’ Automatic push-up counting β€’ Real-time detection using the front camera β€’ Hyakunin Isshu waka progress collection β€’ Modern translations, commentary, and background notes β€’ Poetic places map β€’ Daily records and heatmap β€’ Streak tracking β€’ Japanese & English support β€’ Optional in-app purchase to remove ads Make push-ups a little easier to keep doing.
