You’ll waste six bucks and not drill into a stud. ### 1/5 — Don’t waste your money *2022-12-03, version 2.5.2* Junk, and immediately asks for ab upgrade to keep using. ### 1/5 — Kevin *2022-09-12, version 2.5.2* I never purchased this app….

Even when I put it on studs that I found myself it wouldn’t find them. Don’t waste your $6 ### 1/5 — Doesn’t work *2022-06-05, version 2.5.2* Doesn’t work ### 1/5 — Bad *2022-06-02, version 2.5.1* Could not get it to show anything ## Most critical reviews (10 lowest-rated) ### 1/5 — Inutile *2026-01-31, version 3.1.1* Ne fonctionne pas! ### 1/5 — Review *2025-07-08, version 3.1.1* I am not having very good luck with this stud finder ### 1/5 — Not happy *2024-09-28, version 2.5.2* False claims do not purchase this product ### 1/5 — Really horrible *2024-07-20, version 2.5.2* Difficult to use and confusing directions ### 1/5 — Duvidoso *2024-04-11, version 2.5.2* Se a capinha do celular pode interferir no sensor, como é mencionado no app.. imagina o que uma parede não pode fazer hein 🤔🤔 ### 1/5 — Absolutely worthless waste of time *2024-02-05, version 2.5.2* First off the App Store is a complete and utter lie. It has a 4.1 rating with only 2 5 star reviews and one of those was an accidental 5 star. Everything else is under 2 stars. I hope the developers of this app catch a extremely curable disease but are discomforted for as long as this app took me to deal with ### 1/5 — Cobrança indevida *2024-02-01, version 2.5.2* Cobrança sem aviso prévio. App ruim, péssimo ### 1/5 — Does not work! 😤 *2023-10-20, version 2.5.2* Shortly after downloading this app and reading the instructions it asked to get the full version for £5.00… And £5.00 for nothing!! Even by increasing the sensor sensitivity, the best reading I could get was a value of 20 which did not stabilise (as I moved across the wall that same reading extended to every location on the wall I was scanning through). I found another app (free this one!) with a very similar logo and it worked just fine by adjusting to the right sensitivity until I got a signal. If you are considering this app like I did pass your way! ### 1/5 — Free for exactly 3 seconds. Total scam *2023-09-17, version 2.5.2* Didn’t even find the KNOWN stud during those 3 seconds ### 1/5 — Trash *2023-08-09, version 2.5.2* Trash doesn’t work ## Most praised reviews (6 highest-rated) ### 5/5 — good *2026-01-20, version 3.1.1* Great job for this app. I tested it on uranium and dude. This is so cool and don't forget I'm a scientist ### 5/5 — Is not working *2021-12-23, version 2.5.1* It’s not worthy. Spend money for nothing ### 5/5 — Good *2021-11-29, version 2.5.1* Good ### 5/5 — Contractor tool box *2021-08-25, version 2.5.1* Stud finder is now on call in my digital tool box . I use it daily and it’s as accurate as the $300 stud finder I have not used since purchasing this app ### 2/5 — Poor *2023-06-10, version 2.5.2* I was told to get the upgrade but it didn’t improve anything. It works on a knife but not at all on a wall ### 2/5 — Come On Man *2023-05-22, version 2.5.2* I loaded this to try it out. I had it less than 1 minute and it said my trial time is up and prompted to purchase. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
