Frequently asked questions

Do I need an account?: No. HydroDrop works entirely on your device, with no sign-up required.
Is my data backed up?: Yes. Your log lives on your device and, when you are signed in to iCloud, in your private iCloud account. That keeps it in sync between your iPhone and Apple Watch and restores it on a new device. HydroDrop has no servers of its own and never sees your data.
What does HydroDrop+ include?: HydroDrop+ removes ads, extends your History chart from the last 7 days to the last 30, and adds the Apple Watch app and the Home Screen and Lock Screen widgets. It protects your streak with one automatic freeze a month, makes reminders pace-aware so they stay quiet when you are already ahead, and adds a weekly recap, hot-day suggestions and a Live Activity. It also unlocks Insights from Apple Health, seven more decorations for your droplet's world, and four more mascot skins, each with a matching Home Screen icon. You can subscribe monthly or yearly, or pay once for HydroDrop+ Lifetime, and either way you support continued development of the app.
My widget shows a lock: Widgets are part of HydroDrop+. If you have HydroDrop+ and still see the lock, open HydroDrop once so it can refresh the widget. If that does not help, tap the gear to open Settings. If it shows Upgrade to HydroDrop+, tap that, then Restore Purchases. If it already shows HydroDrop+ as active, email support@hydrodrop.us.
I bought HydroDrop+ but my features are missing: Tap the gear to open Settings, then Upgrade to HydroDrop+, and tap Restore Purchases. Make sure you are signed in with the Apple Account you bought HydroDrop+ with. If Settings already shows HydroDrop+ as active and something is still locked, email support@hydrodrop.us.
How do I cancel my HydroDrop+ subscription?: Tap the gear to open Settings, then Manage Subscription, just below the line that says HydroDrop+ is active. Or manage it under your Apple Account, then Subscriptions, in the iOS Settings app. HydroDrop+ Lifetime is a one-time purchase, so there is nothing to cancel. If you switched to Lifetime, cancel your old subscription the same way so it doesn't renew.
How do I remove the ads?: The free version shows a small banner ad, except in the European Economic Area, the UK and Switzerland, where it shows none. HydroDrop+ removes the ads completely.
I am not getting reminders: Check that notifications are allowed for HydroDrop in iOS Settings, that Reminders is on in the app, and that the current time falls inside your reminder window.
