# App Crashes & Persistent Glitches

An app closing unexpectedly is considered a crash. While some glitches are random and temporary, recurring issues will require troubleshooting.

There are two main things you can try.

***

#### Reset or Reduce Memory

A memory warning can appear when your iPad is running low on available memory (RAM) while trying to perform a task. It doesn’t mean something is broken — it’s just the system’s way of saying it’s getting overloaded and needs to free up space to keep things running smoothly.

Our app uses multiple processes for taking, editing, and uploading photos, all of which require a fair amount of memory. Try these steps:

* [Close other apps](https://support.apple.com/109359) running in the background
* [Restart your iPad](https://support.apple.com/101603)

If the issue continues, try disabling certain effects (like glam, filters, or participant editing tools) to reduce processing demands.

## Devices with limited processing

If your iPad has limited processing power and you're using demanding tools, a warning appears when you launch your event.

It lists enabled settings that may reduce performance. You can disable those tools before launch.

#### Reinstall the App

Sometimes small bugs can pop up after updates or changes. Reinstalling the app gives it a fresh start and often clears things up.

1. Prepare to reinstall\
   Make sure you’re connected to WiFi and have both your Simple Booth login and Apple ID credentials ready.\
   \&#xNAN;*<mark style="color:$warning;">Pending uploads will be lost if you delete the app before checking your queue.</mark>*
2. Check for updates\
   Ensure your iOS is current. The latest app versions require iOS 17 or later.
3. Delete & reinstall the app
   1. Delete the app from your iPad.
   2. Open the App Store and search for (or use the links below):
      * [Simple Booth HALO](https://apps.apple.com/us/app/simple-booth-halo/id1323267760)
      * [Simple Booth Classic](https://apps.apple.com/us/app/simple-booth-classic/id697826715)
   3. Re-download and log in, then test the app.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.simplebooth.com/running-your-event/quick-troubleshooting-guide/app-crashes-and-persistent-glitches.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
