Currently in order to start a 5k Training Workout you will need to have a Text-to-Speech engine installed on your phone and selected as ‘default’. If you’re not able to start up a Workout then there may be problem with the Text-to-Speech engine on your device.
To check this please go to Settings > Language & Keyboard > Text-to-Speech output. You should then see a list of available TTS engines. If none of these is selected we recommend choosing Google's TTS engine as this works best with Zombies, Run!
Once you have done this you should find the app no longer crashes when you try to start a Workout. If you do still have problems however then please get in touch with us at firstname.lastname@example.org.
