Nestis is a calm, focused intermittent fasting timer that also helps you see whether it is working: for your weight, your waist and how you feel.
Start a fast, and Nestis shows exactly where you are: how long you have fasted, when your goal lands, and which phase is next, from early fast through glycogen, fat burn, ketosis and autophagy. No clutter, no noise.
FAST YOUR WAY
- Pick a rhythm: 12:12, 14:10, 16:8, 18:6 or 20:4
- Choose a flexible window, or schedule your start time and get a gentle reminder
- Edit your start time anytime if you forgot to tap
- Gentle reminders at each milestone, water breaks, and when your goal is reached
THREE WAYS TO WATCH YOUR FAST
- Typographic, Ring and Liquid timers, all built to be glanced at
SEE HOW YOUR FASTS FEEL
- Rate your energy and hunger after each fast in about ten seconds
- See how your fasts felt, week by week and month by month
- With Pro, see how your energy and hunger change as your fasts get longer
- Short summaries are written on your iPhone by Apple Intelligence on supported devices, and nothing leaves your device
STAY ON TRACK TO YOUR GOAL (PRO)
- Set a weight goal and watch your weight trend toward it, by week, month, six months or year
- See progress the scale can miss: waist-to-hip and waist-to-height ratios track belly fat, shown against WHO and NICE targets
- Skip the typing: connect Apple Health to import your scale readings and save what you log. It is optional
- Your weight and measurements stay on your iPhone and in Apple Health. They are never sent to iCloud
SEE YOUR PROGRESS
- Weekly trends, hit-target rate and longest fast
- A streak calendar of your last six weeks
- A private journal: log how you feel after every fast
ALWAYS WITHIN REACH
- Home Screen and Lock Screen widgets
- Live Activity and Dynamic Island for the final stretch of a fast
YOURS
- Your fasts and journal sync across your devices with iCloud
- Export to JSON, CSV or a printable PDF, and import a backup
- Five themes in light and dark, with matching app icons
