What is the simplest way to track a fast?

Last reviewed · Jun 29, 2026 · Not medical advice
Quick answer

The simplest way is to record start time, target hours, end time, and whether you completed it.

Step by step

01 Write down what you need: timer, reminders, widgets, history, or privacy.
02 Avoid apps that make the first fast harder to start.
03 Try one schedule for a week and review your history.

The longer answer

The simplest way is to record start time, target hours, end time, and whether you completed it. For Fast Goblin, the page should teach the reader the evaluation criteria, then show why a cute, simple iPhone-native fasting tracker is useful.

Tip

The right app makes fasting boring in the best way.

Common mistake

Downloading a complex app and then avoiding it because it feels like homework.

Track in the app

Track start time, end time, presets, notes, reminders, and completion rate.

Safety note
Educational only. People who are pregnant, breastfeeding, under 18, have diabetes, take glucose-affecting medication, have a history of eating disorders, or feel unwell should speak with a qualified clinician before fasting.
