A. 1. Ensure your iPhone is running the latest version of iOS. Go to Settings > General > Software Update and install any available updates. 2. Close other apps running in the background to free up memory. Double-click the Home button (or swipe up from the bottom on newer models) and swipe up on apps to close them. 3. Delete and reinstall the Two Dots app. This can clear any corrupted data that may be causing crashes. 4. If the problem persists, try restarting your iPhone by holding down the power button and sliding to power off, then turning it back on.
