Two different kinds of app
Simple's App Store listing calls it an AI weight-loss coach and doesn't use the word fasting; its help pages explain how to log fasts from its Track page. Its free version, its help says, lets you log fasts, meals, hydration, weight and activity, with more in Pro and Premium. Fasting Tracker does one thing: it times your fast and shows the stage your body may be in, with your streak, history, weight and water.
Price
The US App Store lists Simple Pro at $14.99 to $49.99, Simple Premium at $29.99 and $59.99, and a Workbooks Bundle at $29.99. Simple's help says it offers monthly, quarterly, 9-month and yearly plans, with prices shown at checkout, so we can't say which price covers which period. Fasting Tracker Pro is $6.99 a month, $29.99 a year (about $2.50 a month) with a free first week, or $79.99 once for life.
Privacy and age rating
Every App Store listing has an App Privacy label, filled in by the developer. "Data Used to Track You" means data linked with other companies' apps, websites or data for advertising, or shared with data brokers. "Contains Advertising" appears in the age-rating details when an app shows ads. Fasting Tracker's label lists no data used to track you; it does link purchase history, identifiers, product interaction and crash data to you, for analytics you can turn off in Settings.
Simple's label lists data used to track you, including purchase history, coarse location, email address, user ID and product interaction, and its age rating lists "Contains Advertising". Its terms say you must be at least 18 to create an account, and it's rated 18+ on the App Store. Fasting Tracker is rated 9+ and needs no account.
Devices
Simple runs on iPhone with iOS 18.3 or later, Apple Watch and Apple Vision, without an iPad app. Fasting Tracker needs iOS 17 and runs on iPhone, iPad, iPhone Duo and Apple Watch.
