Understanding the Zero App Interface
Before you can delete a fast on Zero, it's helpful to understand the different sections of the app where your fasting data is stored. Your logged fasts appear on the main 'Today' screen, within the calendar on the 'Me' tab, and in the 'Recent Fasts' section. Depending on when you need to delete the fast—either immediately after ending it or at a later date—you will use a slightly different path.
Method 1: Deleting a Fast Immediately After Ending It
This is the quickest method if you've just finished a fast and realized there was an error. Zero provides a prompt to edit or delete the fast directly from the summary screen.
- End the fast: Tap the 'End Fast' or 'Complete Fast' button on the main timer screen.
- Access the fast summary: A summary screen will appear. Tap either 'Edit Start' or 'Edit Finish' to open the detailed summary.
- Locate the delete option: On the fast summary screen, look for the 'Delete' button in the bottom left corner.
- Confirm deletion: Tap 'Delete' and then confirm your choice to remove the fast from your log permanently.
Method 2: Deleting a Past Fast from the Calendar
If you've already saved a fast and need to go back to delete it, the calendar view is the most reliable tool. You can access the calendar from both the 'Today' screen and the 'Me' tab.
- Navigate to the calendar: Tap the streak count icon in the upper left corner of the 'Today' screen or tap 'Me' and then 'See All' in the calendar section.
- Select the fast: Tap on the specific date containing the fast you wish to remove.
- Open fast details: This will open the fast's details page. Tap the 'Delete' button.
- Confirm removal: Confirm your action to delete the fast.
Method 3: Long-Press Deletion (Alternative Calendar Method)
For quick removal from the calendar view, there is a convenient long-press option, although this may vary slightly between app versions.
- Go to the calendar: As in Method 2, access the calendar via the 'Me' tab or the streak count icon.
- Long-press the fast: Find the fast you want to delete and press and hold on it until a menu appears.
- Select 'Delete this fast': A pop-up menu should give you the option to delete the fast directly.
Comparison of Deletion Methods

| Steps Required | 3-4 taps | 3-4 taps | 2-3 taps |
| Best Use Case | Realizing an error right after ending a fast | Fixing an older, inaccurate entry | Rapidly clearing multiple past fasts |
| What it Affects | Only the fast you just ended | Any saved fast in your history | Any saved fast in your history |
Editing vs. Deleting: Making the Right Choice
Sometimes, you might not need to delete a fast entirely but simply edit its start or end time. For instance, if you forgot to end your fast exactly on time, you can adjust the end time instead of removing the entire entry. This preserves the record of your fast while correcting the inaccuracy. Zero allows you to edit fast times from the same fast detail screens where you find the delete option.
- When to Edit: If you started or ended your fast a bit late, simply adjust the timestamp. This is useful for keeping an accurate log of your fasting regimen without losing the data.
- When to Delete: If you accidentally started a fast, logged a fast that never happened, or need to completely remove an entry for other reasons, deletion is the right choice.
What to Do with Other Data Entries
Beyond fasting, the Zero app allows tracking of other biometric data like weight and sleep. Deleting these entries follows a similar, but distinct, process:
- Access the 'Me' Tab: Navigate to the 'Me' section of the app.
- Find the graph: Scroll to the graph for the data you want to edit or delete, such as 'Weight'.
- See all data: Tap 'See all data' to view the full list of entries.
- Delete an entry: Locate the entry with a pencil icon next to it, tap it, and select 'Delete entry'. Data synced from other apps like Apple Health may need to be deleted from the source app.
Conclusion
Deleting an erroneous or unwanted fast in the Zero app is a simple process, with multiple routes available depending on your specific situation. Whether you catch the mistake right away on the summary screen or need to fix a past entry through the calendar, the app provides the necessary tools. This flexibility ensures your fasting log remains accurate, helping you stay on track with your health and wellness goals. Remember that for minor time adjustments, editing is often a better choice than complete deletion.

Troubleshooting: Syncing and Presets
If you have trouble deleting an entry, especially one synced from another app like Apple Health or Google Fit, you may need to delete it from the original app first. Additionally, if you need to remove a fasting preset instead of a specific fast, the process is different: navigate to the change fast goal screen, tap 'Edit' next to 'Your Presets', select the preset, and then tap 'Delete'.
