Tap the butt. Build the habit. CorgiKetu is a ridiculously cute habit tracker that turns "sticking with it" into something you actually look forward to. Just tap the corgi's fluffy butt — and watch your habits add up. Squats. Push-ups. Reading pages. Glasses of water. Any habit you can count, you can boop. WHY YOU'LL LOVE IT ▸ Built for people who've quit every habit app No pie charts. No guilt. Just a corgi butt that wiggles when you tap it. Somehow, that's enough. ▸ Streaks that actually motivate Hit your daily goal and watch your streak grow. Miss a day? The corgi still loves you. Probably. ▸ One-second logging Open app. Tap butt. Done. No forms. No friction. FEATURES ◎ Tap-to-count Every tap on the corgi's butt adds one rep. Accidental tap? Flip to minus mode and subtract. ◎ Daily goals Set any target from 1 to 999. Start small, grow brave. ◎ Streak tracking See how many days in a row you've hit your goal. Don't break the chain. ◎ History view Look back at your streaks and wins on a simple calendar. ◎ iCloud sync Switch phones? Your data comes with you. No sign-up needed. PREMIUM (One-time $2.99) Pay once. Own it forever. No subscriptions, ever. • Add unlimited habits (free version: one habit) • Remove all ads • Unlock 3 seasonal skins: Sakura, Maple, Snow FROM THE MAKER I'm someone who has downloaded — and deleted — every habit app on the App Store. Too many graphs. Too much nagging. Too much pressure. So I made the opposite. An app that's just a corgi butt you want to visit. Once a day. Forever. If you've ever rage-quit a habit app, this one's for you. SUPPORT & PRIVACY Tap Settings inside the app for our Privacy Policy and contact form. We read every message. Now go boop that butt.

Verdict
The clearest difference is ads: CorgiButts at none against 逆算日記's shown. 逆算日記's advantage is iOS requirement (17.6 vs 26.2). On price, in-app purchases and device support there is nothing between them.
