Fastic — free intermittent fasting app for mobile devices

Fastic is a no-cost smartphone app that helps users track and manage eating windows and habits. Whether your goal is to lose weight or simply eat less, the app bundles several practical tools to support fasting routines and healthier choices.

How intermittent fasting contributes to weight control

Research indicates that intermittent fasting can be an effective method for lowering body mass index (BMI) over time. For people who haven’t had success with other approaches, structured fasting schedules may offer an alternative pathway to progress.

Key tools included

  • Step counter for tracking daily movement
  • Daily water intake logging to encourage proper hydration
  • A fasting clock to monitor eating and fasting intervals
  • Short motivational tasks each day to help maintain consistency

Note: Additional features are unlocked in the premium edition.

Compatibility and storage needs

Fastic works well as a standalone solution and can also be paired with other wellness apps, for example food trackers like FatSecret. The app is lightweight and does not demand much storage space on most devices.

Who will find this helpful

The interface and feature set are built to suit both beginners trying fasting for the first time and experienced users refining their routines. The design aims to be broadly useful rather than tailored only to specialists.

Popularity, extra resources, and expert support

With more than 25,000 downloads, Fastic has achieved substantial user adoption comparable to many mainstream activity-tracking tools. Subscribers gain access to 400+ healthy recipes and input from nutritional experts, making the app a practical supplement to a weight-loss plan.
