Make a vow
Decide what you’re training for. Keep it going for 30, 66 or 100 days, or set a finish line. Then sign it.
A blade isn’t made in one strike.
Make a vow. Train every day. Watch the days add up until you hold an edge.
Coming soon to iPhoneTrain every day
Your habits sit under the night sky on Today. Check them off, then seal the day.
Earn your rank
Every full day counts, and a missed one never takes your count away. Climb from Iron to Steel, all the way to Shinobu at one year. Ranks never go down.
Show the proof
Share a card that draws every day you trained. Honest numbers, nothing made up.
No account. Your data stays on your phone.
There’s nothing to sign up for. Your vow, habits and history are saved on your iPhone, not on our servers.
忍 Shinobu, from 忍ぶ: to endure, to persevere.
