Guardsman SmartTrackr vs LevelMaster

Guardsman Metaverse SmartTrackr is so much more than an app. It's your new command center and the key to complete vehicle control. Get driving behavior alerts, vehicle document expiry reminders, immobilize your vehicle if it exceeds your pre-set geo-fence...and so much more! If things go off-track, the Guardsman Metaverse team is on-hand to help stop, reverse, or recover. A new dimension of security.

LevelMaster turns your phone into a precision spirit level and angle meter, using the built-in motion sensor — no extra hardware needed. BUBBLE LEVEL • Circular bubble level for flat surfaces — lay the phone on a table, shelf or countertop • Bar bubble level for vertical surfaces — hold it against a wall, door frame or picture • Automatically switches between flat and vertical modes as you move the device ANGLE METER • Large protractor-style gauge with a live degree readout • "Set as 0°" lets you zero out any starting angle — handy for measuring a slope or a change in angle (e.g. a ramp or a roof) LEVEL ALERT • A confirming beep and a light vibration the instant the device becomes level • Turn the beep or vibration off independently in Settings CAMERA OVERLAY • See a level line through the camera while you hang a shelf, a frame or a piece of art • The line turns green the moment it's level CALIBRATION • Correct small sensor offsets against a known-level reference, per device MADE FOR EVERYONE • Light & dark themes with multiple accent colors • English and Japanese • Keep the screen on while measuring PRIVACY FIRST • Works fully offline. The camera is used only to overlay the level line — nothing is ever captured, saved, or sent anywhere. No account, no cloud, no tracking. Great for DIY projects, hanging furniture after a move, and checking a boat or dock is level while fishing. Note: readings are approximate and depend on your device's sensor. LevelMaster is intended for everyday DIY use, not for professional or regulatory measurements. Free, supported by ads.
