How to Sync with Apple Health
The app syncs your body-weight and new workouts with Apple Health.
The app will update your body-weight in Apple Health if you enter it in our app. Or it will update your weight in the app if you enter it in Apple Health. If you have a digital scale connected to Apple Health, it will automatically update your body-weight into the app. This saves you entering it twice.
New workouts will also show in Apple Health, with total workout time and calories burned. We estimate calories using your workout duration and body-weight. This isn't 100% accurate, but no calorie calculator ever is. The point is to give you a rough idea. Lifting weights is about more than burning calories anyway.
Workouts Don't Sync
If new workouts don't show in Apple Health, please check this:
- Open StrongLifts and go to settings - Apple Health. Enable "Sync with Apple Health" so a green button shows.
- Open the Health app. Tap "Sources" a the bottom and choose StrongLifts. Allow StrongLifts to write data for Active Energy, Weight, and Workouts. These three options must all have a green button so StrongLifts can update Apple Health.
- Log a new workout. Set the date of the workout as today (tap the date at the top). Enter all sets then tap done. Calories will be low because the workout only lasted a couple of seconds as you entered it quickly. But the workout should show.
Please note that old workouts won't show in Apple Health. Only new workouts will show.
Note also that StrongLifts syncs with Apple Health. It does not work with Apple Watch or Activity at this moment. So open Apple Health.
Resumed ongoing workouts may not always sync to Apple Health. We plan to have a fix in a future version of the app. For now, please use this workaround:
- Delete any ongoing workout before logging. If you open the next workout before logging it and then tap back, it will show as ongoing. If you then resume that ongoing workout the next day, it will not sync to Health when you tap finish. Workaround: delete the ongoing workout before logging it (open the ongoing workout, then tap the delete icon at the bottom). Or simply don't open the next workout in advance.
- Avoid switching between apps during your workout. Sometimes the app will resume on the homescreen instead of the log workout screen, after switching between apps. Your workout will be marked as ongoing. If you then resume it and tap finish, it will not sync to Health. Workaround: avoid switching between apps during your workout. Or if you did, delete the ongoing workout and log it again (your workout duration will be off in this case, but at least it will show in Health).
Again, we have fixes coming for the above two cases in a future version of the app.
Wrong Workout Duration
The workout duration that shows in Apple Health may be different from your actual workout duration.
The start time/date is currently set when you open a workout and it's marked ongoing. This start time/date is sent to Health when you tap finish.
It seems some people open the next workout in advance (to review the weights for example). When you do this and tap back, that workout is marked as ongoing. When you then tap finish, the workout time in Apple Health will be off.
The workaround here is to avoid opening the next workout in advance. If you do it anyway, delete the ongoing workout (open and tap delete). There should be no ongoing workout on your homescreen before you log it.
We plan to have a fix for this too in a future version of the app.
Apple Watch Warning
The StrongLifts app does not work with Apple Watch at this time. We plan to add this in the future (can't say when). For now, do no track your workouts with your Apple Watch and the StrongLifts app the same time. If you do so, Apple will save the Apple Watch data and thus the StrongLifts data will not show in Health.
It may be possible to prioritize the data sources (see - https://support.apple.com/en-us/HT204351). But easier is to only track with the StrongLifts app as we are sending the total workout time plus estimated calories burned to Health anyway. The Apple Watch data is redundant.
