1. Update to a new version. We are constantly working on improving the speed and performance of the app. To get the latest version, you just need to completely close and open the app on your device, or refresh the browser if using the web app. 
  2. Turn the transparent theme off. The solid color themes are much faster!
    To do this, click on your profile icon to open the settings. Select "Background" and switch the "Transparent" switch to 'off' (if it is off, it should be grey).
    Learn more about themes here.
  3. Archive "Done" tasks. When you open a list, completed tasks are loaded alongside the active ones and if you've got a lot, this can take time! To archive done tasks, tap "Done" at the bottom of your list of active tasks, then choose "Archive Tasks".
