### 2/5 — Only free 10 seconds then 10sec ad, repeat

*2026-08-22, version 1.3.5*

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

### 1/5 — Scammer Does not work

*2026-08-16, version 1.3.5*

No page inside the app. It does not work. Scammer, need refund. There is no way to get the refund

### 1/5 — Pain to Use

*2026-08-08, version 1.3.5*

Trial version is useless and constantly pushing to upgrade by blocking free trial usage.  Horrible!

### 1/5 — Useless

*2026-08-05, version 1.3.5*

Can’t use the app for 5 seconds without being diverted to a paywall asking you to upgrade to premium.

### 1/5 — Do not get

*2026-07-22, version 1.3.5*

You only get to use for 5 seconds before you have to wait 10 seconds to use again. The constant pausing make this app unusable

### 1/5 — Scam

*2026-07-20, version 1.3.5*

There is zero way to cancel if you upgrade.

### 1/5 — Only detects metal

*2026-07-16, version 1.3.5*

Studs are made of wood

### 1/5 — It’s not free

*2026-07-12, version 1.3.5*

This app is a joke, it kept popping up adds for $1.99 upgrade every .10 seconds. All I need is to find a stud once why would I pay a fee from a free app?

### 1/5 — Nothing but ads

*2026-07-03, version 1.3.5*

You can only use the app for about 5 seconds before being prompted to upgrade or wait 10 seconds to continued followed by the same pop up only 5-10 seconds later

### 1/5 — Did not work

*2026-06-19, version 1.3.5*

This app does not find studs. Waste of time.
