Use Screen Time for a basic limit, Downtime for scheduled access, or an iPhone app blocker when checking timelines across servers becomes a habit you didn't plan, without deleting your account.

Everything you need to stay focused, right from Home.
You can block Mastodon on iPhone without deleting your account. Use Screen Time App Limits for a daily allowance, Downtime for a scheduled block, or a dedicated blocker when Mastodon needs to stay unavailable by default. Each method restricts access differently, so choose the smallest one that closes the loophole you actually have.
Mastodon's decentralized structure changes how the checking habit forms. Instead of one algorithmic feed, you have a home timeline, a local timeline for your server, and a federated timeline pulling from other servers, plus whichever client app you've chosen to use. More timelines and more client options mean more separate places a quick check can happen.
1. Open Settings, then tap Screen Time. If needed, turn on App & Website Activity. Tap App Limits, then Add Limit.
2. Select Mastodon or your specific client. Search for the exact app you use, since Mastodon has several official and third-party clients, tap Next, choose the daily allowance, then tap Done. Selecting the specific app on its own avoids sharing a limit with other apps you still need.
3. Know what happens when the limit is reached. iPhone shows a Screen Time limit screen, but an App Limit can be ignored by default. That matters here specifically: if you switch between multiple timelines or servers, a single app limit only covers the one client you actually set it on.
Check that the App Limit applies to the exact app you use. Open Settings > Screen Time > App Limits, tap the rule, and confirm the correct Mastodon client is selected. If you switch between the official app and a third-party client, or use Mastodon through a browser bookmark, each is a separate surface that needs its own restriction.
Do not confuse an override with a failed limit. If you see an Ignore Limit option, the limit has triggered as designed. It is an expected iPhone override, not proof the app was never restricted. See how to stop ignoring Screen Time limits if that override has become automatic for you.
Check the workaround you are actually using. Muting notifications or hiding an icon doesn't block Mastodon. If you check your server's website directly in Safari as a workaround, that's a separate boundary that also needs its own restriction.
Downtime blocks most apps during a scheduled period. Go to Settings > Screen Time > Downtime, choose Scheduled, and set the days and hours. This works well for a work block or evening wind-down, when checking multiple timelines across servers is most likely to eat into time you meant to spend elsewhere.
Turn on Block at Downtime for a real scheduled block. Apple lets Downtime show a reminder by default; with Block at Downtime enabled, restricted apps cannot open during that period. Apps in Always Allowed can remain available, so review that list if Mastodon is not behaving as expected.
Focus Mode is not a Mastodon blocker. Focus can silence notifications and reduce visual cues; it does not stop you opening the app directly.
| Approach | Good for | Weak point |
|---|---|---|
| Delete Mastodon | Removes immediate access on this iPhone. | Can be impractical if you're active in a specific community on your server. |
| Screen Time app limit | Basic limits and awareness. | Only covers the one client you set the limit on; a second client sidesteps it entirely. |
| Fella | Blocking your chosen Mastodon client by default. | Built for one 5-minute emergency unlock per session, not open-ended access. |
A dedicated blocker is useful when timeline-checking has become a reflex across whichever client happens to be open. Because Mastodon's ecosystem spans multiple apps and servers, a default-off rule on the specific app you use removes the decision entirely, rather than hoping you remember to respect a limit on each one. If you are still choosing a tool, see our iPhone app-blocking options.
With Fella, add your Mastodon client to the apps you want blocked. It stays unavailable by default while the apps you did not select remain accessible.
Use the emergency unlock only for a practical need. Each blocking session includes one 5-minute emergency unlock, enough time to check a specific reply or DM. When the five minutes end, the app locks again automatically.
That is the trade-off. Fella is for stronger friction, not flexible schedules, multi-client coverage in one rule, or a way to post while staying blocked from browsing timelines.
People who check the federated timeline out of habit, not intent. If you're not sure why you opened it, that's the pattern Fella is built to interrupt.
People who are genuinely active in a specific community. The emergency unlock gives you a window to reply to something specific without leaving the app open and reachable all day.
People who've already tried app limits on one client, only to open a different one instead. If switching clients has become the workaround, a harder default on the app you actually use is the next step.
Use Screen Time App Limits for a daily allowance, Downtime for scheduled hours, or a focused app blocker like Fella to keep Mastodon blocked by default with one 5-minute emergency unlock per session.
No. Fella blocks access to the app on your iPhone. Your account, your home server, and your posts are untouched, and you can still reach them during your one 5-minute emergency unlock per session.
Fella blocks whichever specific apps you choose to add to your list. If you use a third-party Mastodon client instead of the official app, add that specific app to your blocked list.
Yes. Use App Limits for a daily allowance, or Downtime for scheduled hours. A reached App Limit can be ignored by default. Fella is a narrower blocker with one 5-minute emergency unlock per session.
Yes. You choose which apps Fella blocks. Mastodon can be on your list while other apps you rely on stay fully accessible.
No. An app blocker applies to the app itself. Your Mastodon server accessed through Safari is a separate website boundary, and it needs its own restriction if browsing there is your usual workaround.
Delete the app, then go to Settings > Screen Time > Content & Privacy Restrictions > iTunes & App Store Purchases > Installing Apps and set it to Don't Allow. This blocks new App Store installs system-wide, including Mastodon or its clients, until you turn it back on with your Screen Time passcode.
