Gobogi is a simple timer for tracking your intermittent fasting. No ads, no login — built with just what you need. ■ Set it once Pick your start time and duration, and each day's fast is calculated for you. Open the app late? It fills in the window you missed. ■ Past your goal is fine Your goal is a marker, not a stop button. Go over it and the timer keeps counting as "in progress," then saves at the moment you end. ■ A rhythm that adds up A whole month in one calendar. Days you fasted show up darker, days off stay empty, so the pattern is easy to read. Weekly averages and the days you hit your goal are there too. ■ The first meal after a long fast Not every meal — just the one that breaks your fast, logged simply. Pick a food and its calories and nutrition are saved with it. ■ Home screen widget See your current fast right from the home screen, no need to open the app. The turtle walks as far as you've come. ■ Reminders Get notified at your start and end times. End early, and the leftover reminders quietly clear themselves. Calm and steady — slow like a turtle, but consistent. No ads · No account · Free

Verdict
The clearest difference is ads: Gobogi at none against FastTime's shown. FastTime's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
