About this app

Level & Compass is a bubble level and a compass in one small app. The screen is the instrument: big, clear numbers, a vial drawn to scale, and no clutter. Tap "Level" or "Compass" at the top, or swipe between them.

Every reading also shows how far you can trust it. When the phone is not calibrated, the app says so.

LEVEL
• Surface mode: lay the phone flat. The bubble moves in a vial drawn true to scale, with a tick for each degree and rings at 5° and 10°. You see the X and Y angles in tenths of a degree.
• The accuracy is drawn, not hidden: a dashed halo around the centre shows how accurate the reading is.
• When it is level, the whole screen glows, the number changes colour and the phone gives a gentle tap.
• Edge mode: stand the phone on its edge against a shelf, a picture frame or a door frame. The app switches by itself. A liquid horizon shows the true level line, and plain words tell you "Right side low" or "Left side low".
• Degrees or % slope.
• Hold: freeze the reading, then read it at your own pace.

FLIP CALIBRATION
No phone sensor is perfect from the factory. The flip calibration finds your phone's own error and removes it.
• Put the phone down on any flat spot. It does not need to be level.
• Turn it half a turn on the same spot. On most phones, the screen shows how far you have turned, live, up to 180°.
• Let go. Both readings take themselves.
• A result page shows the error that was removed, and how much the surface slopes and in which direction. Undo if you change your mind.
You can calibrate the surface and the edge separately, and reset the calibration in Settings.

COMPASS
• A dial that turns the short way round under a fixed line, with the heading in degrees and N, NE, E and so on.
• A shaded wedge at the top shows how far the heading may be off.
• Mark a bearing and follow it. A pill tells you what to do, for example "Turn 24° right to 297°". The phone taps when you are back on the bearing.
• A light tap as you pass north, east, south and west.
• If a magnet or metal bends the reading, a card says so and tells you what to do.
• If the compass is not sure, the app asks you to move the phone in a figure 8.
• Works flat or upright. When upright, the back of the phone points the way.

MADE TO BE CALM
• No ads.
• The level and the compass use only your phone's sensors.
• Light, dark or system theme. Reduce motion. Haptics full, subtle or off.
• The screen stays on while you measure.

PRO (ONE-TIME PURCHASE, NO SUBSCRIPTION)
• True north: corrects the compass for magnetic declination. It reads your rough location once, on the phone.

Accuracy depends on your phone's sensors. For the best level readings, do the flip calibration. Keep the compass away from metal, magnets and magnetic cases.
