About Planck Fasting
Planck Fasting is an intermittent fasting timer that gets out of your way. Pick a protocol, hit start, and the timer runs. When you break your fast, it goes into your history. That is the whole app. PROTOCOLS 14:10 for a gentle start 18:6 for deeper ketosis 20:4 for advanced fasters FEATURES A live ring that shows how far into the fast you are Clean history of every completed fast with start time, end time, and duration Pick your default protocol once and forget it Dark UI built for late nights and early mornings Works fully offline Syncs across your iPhone and iPad through your private iCloud database PRIVACY No accounts. No tracking. No ads. No analytics. Your fasting data lives on your device and in your own iCloud, nowhere else. NOT MEDICAL ADVICE Planck Fasting is a tracking tool, not a medical device. Talk to a qualified clinician before starting any fasting protocol, especially if you are pregnant, breastfeeding, taking medication, or have a history of disordered eating. THE PLANCK SERIES Planck Fasting is part of a small family of focused single purpose apps. Same dark aesthetic, same hbar mark, same idea: do one thing, do it well, then get out of the way.
