A few good questions
Let's clear
things up.
Is Sunwick free?
Yes. The fasting timer, fasting plans, full history, and Small and Medium widgets are free. Sunwick Plus is optional and adds extras. You'll see its price and features before you subscribe.
Do I need an account?
No account or email address is needed. Your fasts, weights, moods, and meal log are stored on your iPhone. Optional photo estimates use an anonymous service ID to manage usage limits. Read our privacy policy for details about analytics and other services.
Is Sunwick right for everyone?
Sunwick is for adults aged 18 and over. It isn't suitable if you're pregnant or breastfeeding, have an eating disorder, or have type 1 diabetes. Talk with a qualified clinician before fasting, especially if you have a health condition or take medication. Sunwick is a timer and log, not medical advice.
What happened to Phasty?
Phasty is now Sunwick: a warmer home for your fasting routine, with a redesigned timer, a little flame buddy, and an optional eating window log.
