Apple frequently upgrades its operating system (OS) to fix bugs and improve performance. If Todo Math crashes, it may be that you're using an outdated OS. Apple and Google Play offer free OS upgrades to users; to upgrade your OS, open the App Store and search "Upgrade" to find the most recent upgrade. Find more information on upgrades for Apple or Android.
