If your app isn't working as expected, most problems can be fixed quickly with a few simple steps. This guide covers common issues like app crashes, stuck uploads, syncing errors, and printer problems.
App crashes and persistent glitches
An app closing unexpectedly is considered a crash. Some glitches are random and temporary, but recurring issues need troubleshooting.
Reinstall the app
Small bugs can sometimes appear after updates or changes. Reinstalling the app gives it a fresh start and often clears things up.
Prepare to reinstall. Make sure you're connected to WiFi and have both your Simple Booth login and Apple ID credentials ready. Pending uploads will be lost if you delete the app before checking your queue.
Classic users only: sign in with the same Apple ID used for your original purchase before reinstalling.Check for updates. Make sure your iOS is current. HALO 4.x requires iOS 17 or later. HALO 5.0 requires iOS 26.1 or later.
Delete and reinstall the app.
Delete the app from your iPad.
Open the App Store and search for the app, or use these links: Simple Booth HALO or Simple Booth Classic.
Download the app again, sign in, and test it.
Reset or reduce memory
A memory warning can appear when your iPad is running low on available memory (RAM) while performing a task. It doesn't mean something is broken. It's the system's way of saying it's overloaded and needs to free up space to keep things running smoothly.
The app uses multiple processes for taking, editing, and uploading photos, and all of them need a fair amount of memory. Try these steps:
Close other apps running in the background.
If the issue continues, try turning off certain effects, like Glam, filters, or participant editing tools, to reduce processing demands.
Pictures are stuck
If pictures aren't uploading to your gallery or sending by text or email, the cause is usually slow WiFi or an outdated app version.
Check for updates. Make sure your iOS and app are up to date. If your app is only slightly outdated and you're at an event, updating can wait, but update before your next event.
Check your offline queue. Pending photos upload and send automatically once a stable WiFi connection is restored. Slow venue WiFi can delay uploads and updates.
Settings aren't syncing
Syncing issues usually happen because of poor connectivity or outdated software.
Check for updates. HALO 4.x requires iOS 17 or later. HALO 5.0 requires iOS 26.1 or later.
Refresh the app. Quit and reopen the app, or pull to refresh, to trigger syncing.
Check your WiFi connection. Confirm connectivity with a speed test or by opening a website.
Adjust settings manually if needed. Most settings can be updated directly in the app while you wait for a full sync.
