Support

Email support@whatrock.app and a human will read it. Include the specimen, what the app said, and a photo or screenshot if you have one — that is usually enough to sort it out in one reply.

Identifying and results

It could not identify my specimen

Get closer, fill the frame, and make sure the specimen is well lit and in focus — natural light or a bright indoor light works best. Heavily weathered, wet, or dusty specimens are genuinely hard, and WhatRock reports low confidence rather than guessing a name it cannot actually support.

The candidates list shows more than one possibility

That is a Low confidence result. WhatRock shows up to three possible matches with a class chip and a one-line hint instead of picking one and pretending it's sure. Tap a candidate to open its field guide entry and compare.

Why does it say "Only a gem lab can confirm this"?

Gem-grade material — diamond, ruby, sapphire, emerald, alexandrite, tanzanite, moissanite, gold, platinum, and natural meteorites — is always shown at Low confidence with that caution, because only a qualified gem lab or geologist can actually confirm one of those from a photo. Clear quartz and glass are far more common than they look.

The field notes don't match my specimen exactly

Field notes (Mohs band, luster, streak, colors) describe what is typical for the identified species or class, not a measurement of your specific specimen — every card is labelled "Typical for <name>" for that reason. Natural variation is normal.

Free tier and subscriptions

What's free without subscribing?

8 starter entries in the offline field guide, Settings, and these legal pages — no subscription needed. Identifying a rock, mineral or fossil is part of WhatRock Premium; start with a free trial to try it. If you installed WhatRock before this version, you keep 3 free identifications per local calendar day, with the full result card every time — nothing is blurred or gated. No card is needed and nothing is charged unless you subscribe or a trial you started ends.

Will I see ads?

No. WhatRock shows no advertising of any kind, to any user, and includes no advertising SDK.

What does Premium add?

Unlimited identifications, your full collection, the complete offline field guide, and collection notes so you can record where you found something. Premium Weekly is $6.99/week with a 7-day free trial for eligible new subscribers; a second offer for Premium Monthly ($9.99/month, 3-day free trial for eligible new subscribers) may be shown if you close the first. Premium Yearly ($39.99/year) exists but is not offered inside the app. The plan and trial actually shown to you in the App Store at purchase are what apply.

What is the trial reminder?

If you start a free trial, WhatRock can remind you on your device about 48 hours before it ends, so a charge never surprises you. It's on by default — turn it off with the toggle shown when you start the trial, or in iOS Settings for WhatRock's notifications. The reminder is scheduled and delivered entirely on your device; nothing about it is sent to us.

How do I cancel a subscription?

Subscriptions are managed by Apple, not by us: open the Settings app, tap your name, then Subscriptions. Turning off auto-renew there stops any future charge and you keep access until the end of the period you already paid for.

Can I get a refund?

Refunds are handled by Apple under their policies, not by us. Request one at reportaproblem.apple.com.

Privacy

Do you keep my specimen photos?

No. A photo is sent to identify the specimen and is not retained afterward. There is no account and no login, and WhatRock does not collect your location. See the privacy policy for exactly what is handled.

How do I delete my data?

Your collection and any notes live only on your phone. Clear them in Settings inside the app, or delete the app. We hold nothing tied to you that could be looked up.

Collecting

Is it okay to collect what I identify?

That depends entirely on where you are — you're responsible for knowing and following local laws and land rules. Collecting rocks, minerals and fossils is prohibited in United States national parks and restricted in many other public and private areas. WhatRock's field tips are general education, not a recommendation to collect on any specific site.

Everything else

Does WhatRock work on Android or iPad?

iPhone only for now, iOS 17 or later.

Is WhatRock connected to a museum, lab or geological survey?

No. It is not affiliated with, endorsed by, or sponsored by any of them. Public sources like the USGS or National Park Service are cited only as references for the field guide's own content.

I found a bug

Email support@whatrock.app with your iPhone model, the iOS version, and what you were doing. Screenshots help.
