Grumble

Common questions

My steps aren't showing up

Almost always a Health permission. Open the iOS Settings app → Privacy & Security → Health → Grumble, and check that Steps and Walking + Running Distance are both switched on. If you declined the permission when you first opened Grumble, this is where to turn it back on.

Also worth knowing: iPhone step data comes from the phone itself, so steps taken while your phone was on a desk won't be counted by anything, Grumble included.

I bought Grumble Pro but it's not unlocked

Open Grumble's Settings and tap Restore Purchases. Your purchase is tied to your Apple ID, so this works on any device you own — including after reinstalling.

If it still doesn't unlock, email me and I'll sort it out. Apple doesn't tell me who bought the app, so the things that actually help me find your purchase are:

• your Support ID — in Grumble under Settings → About, long-press to copy it
• a screenshot of the Apple receipt (emailed to you by Apple, or in reportaproblem.apple.com)
• roughly when you bought it, and your iPhone model and iOS version

I reinstalled and my monster is gone

Unfortunately that's permanent. Grumble stores everything on your device and nothing on a server, which is what lets it avoid collecting your data — but it also means deleting the app deletes your history, and there's no backup for me to restore from.

Your purchase survives, though. Tap Restore Purchases to get Pro back.

How do I delete my data?

Delete the app. Everything Grumble knows about you lives in its own storage on your phone, so removing the app removes all of it — permanently and completely.

To also have the purchase record held by our payment provider deleted, email me with your Support ID (Grumble → Settings → About) and I'll pass the request on. Grab it before you delete the app — it goes with everything else.

I want a refund

Refunds are handled entirely by Apple — I can't process them. Request one at reportaproblem.apple.com.

If you're in Australia, this doesn't affect your rights under the Australian Consumer Law. See the Terms.

Is Grumble a subscription?

No. Grumble Pro is a one-time purchase. It doesn't renew and won't charge you again.

Version 1 is sold as early access, so how Grumble is priced for new users may change later. That doesn't reach back into a purchase you've already made — see the Terms.

Does Grumble share my health data?

No. It reads step count (including grouped by hour, to work out when you usually walk) and walking & running distance from Apple Health, uses them on your device, and never transmits them anywhere. Full detail in the Privacy Policy.

Notifications aren't arriving

Check they're enabled in Grumble's Settings, and in the iOS Settings app under Notifications → Grumble. Grumble schedules reminders locally on your phone, so they'll work without a network connection.

Something's broken and it isn't listed here

Please tell me — studio@mutterware.com. If the app showed you an error screen, a screenshot of it is the single most useful thing you can send.
