FAQ
Why can't I see my water in Health?
Make sure Water write access is on in “Health › Sharing › Apps › Waterline”, then tap “Sync past entries” in “Me › Apple Health”.
Reminders not arriving on time?
Check system notification permissions and whether a Focus is silencing Waterline. With Smart skip on, you won't be reminded right after you've had a drink.
Apple Watch data not syncing?
Make sure your watch and iPhone are connected and you've opened Waterline on each at least once. Watch entries are saved straight to Health and sync to iPhone once connected.
How is “effective hydration” calculated?
Effective hydration = amount × hydration factor. Water and tea are 1.0, coffee 0.93 and juice 0.9. You can change these in “Drinks & sizes”.
How do I import water from other apps?
In “Me › Apple Health”, turn on “Include water from other apps”. Water that other apps save to Health will count toward today's total.
How do I delete all my data?
In “Me › Data & privacy”, choose “Delete all data”. This also removes the data Waterline saved to Health.
How do I turn on iCloud sync?
Turn on iCloud sync in Me › Data & privacy, then reopen the app. Your log goes only to your own iCloud, so it comes back when you sign in with the same Apple ID on a new phone.
How do I change the app's language?
Waterline follows your iPhone's language. To pick a different one, go to Me › General › Language and reopen the app.
Does Waterline cost anything?
No. It's free, with no in-app purchases and no ads.
