Pacer is designed to count steps on any type of iPhone device. That means if your Pacer isn't counting properly, there's probably something wrong.
Below are some common troubleshooting steps for different models of iPhone:
If you are using an iPhone 4, 4s, 5, or 5c:
- In Pacer's settings, turn on "GPS+ Mode"
- In your iPhone's settings, make sure that "Background App Refresh" is enabled for Pacer
- In your iPhone's settings, make sure that "Location Services" is enabled for Pacer
- When you exit the app, do not force close it (swiping up on the multi tasking menu), as this will stop all step counting functionality until you re-open the app
- Your device might be too low on memory to allow apps to run in the background. Try maintaining some free space on your device and restarting it from time to time
- If you tried all that but your Pacer is still not working, your app might be crashing for some reason. If possible, you can send us your crash logs to investigate.
*Note: Pacer is able to count steps continuously in the background on the iPhone, but if you never open the app, your iPhone will think that you don't care about it and will eventually stop it from counting steps. For that reason, we recommend opening Pacer and checking your steps at least one time per day.
If you are using an iPhone 5s, 6/Plus, or 6s/Plus:
- Make sure that you have enabled "Motion Activity" permission for Pacer in your iPhone settings
- Your iPhone's built-in motion sensor might have malfunctioned. Typically this can be fixed by force restarting your device (hold down on the home and screen lock buttons)
- Try not to manually change your system time (particularly to the future) as time travel can confuse the step counter.
If you are syncing Pacer with Apple Health:
- Make sure that all required permissions are enabled for Pacer inside of Apple Health
- Re-sync your Pacer data with Apple Health (Open Pacer, go to "Me"->"Settings"->"Apple Health" and tap "Re-sync")
