Turn your iPhone into a stud finder. The Stud Finder helps locate studs behind drywall by detecting magnetic changes caused by nails and screws inside the wall. How it works Tap Scan Slide your phone slowly along the wall Watch the meter react as metal fasteners are detected Listen for the alert sound when a stud is found Tips for best results Move slowly and keep your phone flat against the wall Scan from both directions and mark where peaks overlap For extra accuracy, find the most sensitive spot on the back of your phone (magnetometer location varies by model) Features Real-time circular detection meter Adjustable sensitivity (Low / Medium / High) Room-based calibration for more consistent readings Optional sound alert when a stud is detected Built-in How to Use guide Optional Pro upgrade Remove ads Support future improvements Works best on drywall with metal fasteners. Results may vary depending on wall construction. Important (Read This): This app does NOT “see wood.” It detects metal-related magnetic change. If there’s no metal behind the drywall (rare, but possible), there may be nothing to detect. ## Key features - Real-time circular detection meter - Adjustable sensitivity - Room-based calibration - Optional sound alert - Built-in how-to guide - Pro upgrade for ad removal ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Ad Removal | $3.99 | per month | **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Ad Removal | $0.99 | one-time | ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/the-stud-finder/id6471455103/reviews.md ### 1/5 — One the stupidest apps I ever download *2025-11-18* Yes, ladies, sing, gentle, gentle man. This is one of the stupidest app available an Apple Store. ### 1/5 — No directions *2025-08-19* So dumb **Developer response:** Thanks for the feedback — you’re right that earlier versions didn’t explain the scanning process clearly. We’ve since added a built-in “How to Use” guide that explains exactly how to locate your phone’s magnetometer and scan correctly. If you’re open to trying the latest version, we’d genuinely appreciate your feedback. ### 5/5 — finally solved *2024-11-09* I gave this another try this year, can’t believe how accurate it was! thank you developer. ### 1/5 — Does not work and no instructions on how to use *2024-10-06* No instructions - menu only says resume ads or remove ads. No instructions on how it works. Seems bogus ### 1/5 — Isn’t working *2024-09-17* Despite repeated calibrations, the indicator doesn’t deflect at any point on the wall while making contact. I have used several conventional stud finders in the past without issue. Disappointing ### 1/5 — Worst Stud Finder EVER *2024-01-17* If I could sew for the damages it caused I would. This app is as worthless as the person that made it. Total waste of life. **Developer response:** We’re sorry you had a negative experience. Earlier versions didn’t do a good job explaining how the detection works, which caused frustration for some users. We’ve made major improvements to guidance, accuracy, and stability, and we appreciate all feedback that helps us improve. ### 1/5 — Simply doesn't work! *2023-12-20* Simply doesn't work! **Developer response:** We worked out a few bugs, check it out now! ## Frequently asked questions about The Stud Finder ### Does The Stud Finder have ads?
