TrueTilt: Bubble Level Tool

"TrueTilt turns your phone into a precise bubble level and clinometer. Lay it flat to level a shelf, stand it on edge to plumb a wall, or sight through the camera to read a roof's pitch from the ground. Every job that needs a straight line or a known angle, handled by one pocket tool that is always with you.

A level app for everyday jobs

• Surface mode reads pitch and roll at once, so appliances, tables, and washing machines sit flat the first time
• A spirit level app for pictures, shelves, fence posts, and countertops
• The display switches between flat, portrait, and landscape orientation on its own, so the reading is always right side up
• Big digits and a haptic tick at zero, readable from the top of a ladder

Clinometer with camera mode

• Sight distant slopes through the camera and read the angle on screen
• Check roof pitch before you climb — it doubles as a roof pitch app
• Read the grade of a driveway, ramp, or drainage run from where you stand
• Show angles in degrees, percent, or rise over run
• Zero out any position to measure the relative angle between two surfaces

An angle finder app you can trust

• Calibrate all four edges, the front, and the back against any flat surface
• Hold a reading with one tap and write it down when your hands are free
• Use it as an angle meter app for saw setups, bevels, and miter cuts
• Pick your response speed: fast for rough carpentry, damped and steady for fine work
• Scale marks down to a tenth of a degree

Inclinometer app for vehicles and the outdoors

• Level your RV or trailer on site with the tilt meter view
• Mount the phone in the cab and watch pitch and roll in real time on off-road trails
• Estimate tree heights and trail grades the way foresters do
• Check antenna and solar panel angles at camp

Accurate enough to build on

Every phone's sensors ship with small factory offsets. TrueTilt corrects for them out of the box, and a short recalibration routine removes the rest whenever a reading starts to drift. Set a tolerance and the app signals when you are inside it, so you spend your attention on the workpiece instead of the screen.

Who it's for

Carpenters, DIYers, RV owners, photographers leveling tripods, and anyone who wants a bubble level app in their pocket instead of one more gadget in the toolbox. TrueTilt works offline, starts in about a second, and runs as an Android level app on phones and tablets alike. No account, no clutter, and your measurements stay on your device.

Download TrueTilt and carry a bubble level, a clinometer app, and an angle measure app in one install. Level the shelf, check the slope, and get on with the job."
