About this app

Fastulo is an intermittent fasting timer built around a single idea: make your fast feel tangible. At its core is a smooth animated countdown ring that shows exactly where you are in your fasting or eating window at a glance.

Set your fasting schedule once and Fastulo takes care of the rest. The ring fills and drains in real time, so you always know how much time remains without digging through menus or decoding numbers. Whether you follow a 16:8, 18:6, or any custom split, the timer adapts to your chosen windows.

Everything runs locally on your device. No account, no sign-up, no server. Your fasting history and preferences stay private and accessible even without a connection.

The interface is clean and focused. A single animated ring occupies the main screen, backed by a subtle geometric pattern that keeps things visually grounded without distracting from your progress. Settings are minimal: pick your preferred date format and you are ready to go.

Fastulo does not try to be a nutrition tracker, a calorie counter, or a meal planner. It does one thing — tracks your fast — and does it with care.
