User reviews

Completely unusable without paying for a subscription despite being listed as a free version.

Every time you try to press the on button in the app, it prompts you to subscribe and go pro. Without pressing the on button, the app does not function and does not detect any studs do anything. After exiting out of the go pro prompt, the app resorts back to its non-working state. The app is literally unusable without paying.

Waste of money

Does not work at all. Inconsistent and unreliable.

Unusable

They tried to make me pay to use it or wait a few seconds so it just makes it take so long and it’s basically unusable. I would rather use a real stud finder

Too many upgrade pompts

Takes forever to get through the upgrade ads to where you can actually use the tool. Money money

Only free 10 seconds then 10sec ad, repeat

I’m guessing I found a stud in the 10 seconds the app allows you to scan followed by a 10 seconds ad to purchase their untimed/ad free app version. Even though it’s only $1.99, I’ll go with another app I found that’s free, accurate, and doesn’t have the annoying ad every 10 seconds for free
