Need the drywall screw before you hang a TV or shelf - and tired of stud finder apps that play a fake sweep and never show a number? Stud Peak is a live magnetometer. Hold the top edge to the wall, sweep slowly, and watch the microtesla graph move. When you pass a screw or nail, the field spikes and the phone taps. Prove it on a fridge magnet first. WHAT YOU GET • Live microtesla readout and waveform - not a canned animation • Haptic pulse when the field jumps above baseline • Magnet self-test so you can see the meter actually work • Mark a peak, then step 16 inches for typical US stud spacing • Honest limit: this finds ferrous fasteners (screws and nails), not wood, copper, or live wires • Works on-device - no account PEAK PRO UNLOCKS • Peak history of saved spikes • 16 inch on-center next-stud marks • Ad-free scans The live scan is uncapped. Free plan keeps 1 saved peak. Watch a short rewarded video to save one more, or subscribe for history, 16 inch marks, and no interstitial ads after saves. Phone cases, MagSafe wallets, steel studs, and plaster change the reading. Confirm before you drill. Subscription auto-renews unless canceled at least 24 hours before the end of the current period. Weekly plan includes a 3-day free trial ($4.99/week after trial); annual plan has no trial ($29.99/year). Manage or cancel anytime in your account settings.

Verdict

The call

The clearest difference is in-app purchases: iRhino 3D at none against Stud Peak's 2. iRhino 3D also leads on ads (none vs shown). Stud Peak's advantage is update cadence (every 3 days vs every 3 weeks). On price, device support and iOS requirement there is nothing between them.
