About
Every day you keep going, your penguin grows a little rounder.
Chubby Penguin is a gentle habit tracker. Each time you check off a habit, your penguin grows a little. Exercise, reading, language study, meditation, even your daily coffee: track whatever you want to keep doing.
• ONE TAP TO CHECK IN
Mark today's habits with a single tap. Easy enough for your busiest days.
• WATCH YOUR PENGUIN GROW
Keep checking in and watch your penguin slowly grow bigger and rounder.
• KIND WORDS, EVERY DAY
"You did it!" "One little step at a time." "A fresh start today." Good days or missed days, your penguin is always cheering you on.
• SEE YOUR PROGRESS ON A CALENDAR
Completed days fill with color, so your calendar becomes a record of your effort. Switch to a single habit to review it on its own.
• TRACK YOUR GROWTH
See your completion rate by week, month and year, plus your current streak, best streak and total check-ins.
• SCENERY FOR EVERY SEASON
Spring, summer, autumn and winter. Keep going for a year to collect all four seasons.
• AT YOUR OWN PACE
Choose a goal for each habit: every day, a few times a week, or a few times a month. Set an amount like "30 min", "10 pages" or "3 sets", and choose whether your week starts on Sunday or Monday.
• JAPANESE AND ENGLISH
The app follows your iPhone's language. Switching languages never changes your habits, check-ins or your penguin's growth.
