Here's the fix:
- Update Dilly from the App Store first. Most crashes get fixed in the next build.
- Force-close Dilly and reopen. Swipe up from the bottom, swipe Dilly away, then tap it again.
- If it still crashes, delete and reinstall. Your data is safe in the cloud, so reinstalling won't lose a thing.
If it persists after that, send me a screenshot and your iOS version and I'll dig in.
