Questions & answers
What is intermittent fasting?
Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. It doesn't specify which foods to eat, but rather when you should eat them. Popular methods include 16:8 (16 hours fasting, 8 hours eating), 18:6, 20:4, and OMAD (one meal a day). Research suggests benefits for weight management, metabolic health, and cellular repair.
Is Noxe really free?
Yes. The free tier includes the fasting timer with all 6 basic protocols, the metabolic body timeline, full fasting history with streaks, weight/mood/energy logging, home screen widgets, Apple Watch, and notifications. No time limits, no ads, no account required. Premium adds extended protocols, sleep insights, food logging, progress photos, advanced charts, and more.
How does the sleep insight feature work?
Noxe's sleep insight feature (Premium) connects with Apple Health to correlate your fasting patterns with sleep quality data. After collecting at least two weeks of data, it surfaces meaningful correlations — like how your eating window timing affects sleep duration and quality. All processing happens on your device. Your health data is never sent to any server.
What fasting protocols does Noxe support?
Noxe supports 6 free protocols: 14:10 (14 hours fasting, 10 hours eating), 16:8, 18:6, 20:4, OMAD (one meal a day), and fully Custom schedules. Premium users also get extended protocols for 36-hour, 48-hour, and 72-hour+ fasts with built-in electrolyte reminders to keep you safe.
Does Noxe collect my health data?
No. Your health data stays entirely on your device. Noxe uses TelemetryDeck for anonymous, aggregate analytics only. No personal health data, no advertising identifiers, no user tracking. If you use CloudKit sync (Premium), Apple manages the encryption. Delete the app and your data is gone.
