Magnetic wall scanner & guide

■ Find where it's safe to drill
Mounting a TV, shelf, or handrail on drywall alone is dangerous — screws can pull out. To fix things safely you need to drive screws into a stud. StudSearch uses your iPhone's magnetometer to detect the screws behind the drywall and locate the studs.
■ Works with your walls
・Wood-frame / light-gauge steel (LGS) modes — the magnetic signature differs, so detection is tuned per mode
・Stud-spacing guide: 16" / 24" on center (406/610mm), plus Japanese 303/455mm — find one stud, predict the next
・Real-time graph and readout of the magnetic response
■ Simple to use
1. Take the phone out of its case and reset the baseline
2. Sweep slowly along the wall without rotating the phone
3. When you get a hit, mark it — then trace above and below to confirm a vertical line
■ Guides and safety notes, supervised by a licensed architect
Includes how-to guides for TV mounting, shelves and handrails, plus stud-finding basics, supervised by a Japanese first-class licensed architect. For safety-critical fixtures such as handrails, we recommend a final check with a mechanical (needle-type) stud finder.
※ This app estimates stud positions from magnetic response. Metal other than screws (wiring, pipes, etc.) also reacts. Always confirm by other means before drilling. See the in-app disclaimer for details.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Improved accuracy on wood-framed walls, re-tuned from recordings made on real walls
• Rebuilt the steel-stud (LGS) response: no more stray buzzing in the first seconds, and a steadier hit while you are over a stud
• Simpler Scan screen: a large hit indicator up front, with numbers, graph and sensitivity tucked under “Details”
• A dashed “Sensor” line now shows the height where the screw is — you can save that spot once per iPhone model
• Clearer wording that this is an estimate from magnetism and that sensitivity differs by model
