No gimmicks, no fake promises.

METAL DETECTOR (STUD FINDER)
Find metal studs, screws, nails, pipes and rebar behind walls. A real magnetic metal detector that helps you mount a TV, hang a shelf, or avoid drilling into a pipe. Detects magnetic (ferrous) metal.

BUBBLE LEVEL
A precise digital bubble level / spirit level for hanging pictures, shelves and frames. Lay your phone down and level any surface within a degree.

SOUND METER
A handy decibel / sound level meter to measure noise — loud neighbors, offices, events or machines. See live loudness at a glance.

EMF METER
A clean EMF meter and magnetic field detector. Measure magnetic field strength in microtesla (µT) — spot magnets, motors, speakers and transformers.

COMPASS
A fast magnetic compass that shows your heading and direction. Great for hiking, travel and orienting maps.

VIBRATION METER
Measure vibration and shake — perfect for checking washing machines, appliances, fans and motors.

STOPWATCH
A clean stopwatch with lap times for workouts, cooking and projects.

WHY SMART TOOLBOX
- All-in-one toolbox: stop installing 7 separate apps
- Honest by design: we tell you exactly what each tool can and can't do
- Beautiful, fast, dark interface
- Works offline — no account needed

WHAT TO KNOW
These tools use your phone's built-in sensors, so accuracy depends on your device. The metal detector finds magnetic metals only (not copper, gold or aluminium). The sound meter shows relative loudness, not calibrated SPL. Always verify with professional equipment before drilling, cutting or making safety decisions.
