Snap a photo and find out if it's a real Rolex. Identifier apps for oddly specific things are a business.
The idea: AI identifier apps for jewelry, watches, gems and cars
A cluster of small apps identify one category of thing from a photo. Jewelry Identifier ($14K verified all-time), Watch Identifier ($8K), Car Identifier ($15K) and Gemstone Identifier ($6K) all have verified revenue. Each one targets a hobby where people love knowing what they've got.

Who pays

How it makes money
Weekly or annual subscriptions.
How to start your own
- Pick a category with passionate collectors (sneakers, coins, vinyl, mushrooms).

- Win on App Store search for '[thing] identifier'.
The catch
Authentication claims are risky. Say 'likely' and never certify authenticity.
