Fast at your own pace on a quiet island.
"Angel and Devil Fasting" is a fasting support app that makes starting, measuring, understanding your body's changes, and continuing your fast much simpler.
Should you stop the timer, or push on a little longer? If you're unsure, ask the angel and devil on your shoulders.
■ For you if:
・You want to try 16:8 or 14:10 fasting
・You want to know "what's happening to your body right now"
・You're tired of monthly subscriptions and annoying notifications
・You want to continue fasting in a fun way without being too strict
■ Main Features
⏱ Simple Timer
Complete in just two taps: start and goal. See elapsed time and progress towards your goal at a glance.
You can even adjust the start time afterward, so "actually starting two hours ago" is OK.
🪽😈 Angel and Devil Companions
Gentle voices of an angel and a devil interact on the left and right sides of the home screen.
Sometimes, character breakdowns (angelic transformation, devilish tsundere) provide moments that will make you chuckle.
