How the Timer Level Works

The timer level solves a problem: when you place your phone flat on a surface, your hand touching the screen messes up the reading. This tool gives you a 3-second countdown so you can set the phone down and step away before it captures the measurement.

Start by tapping Check Level to activate the sensors. Move your phone around — you'll see the bubble tracking in real time. When you're ready to measure, tap 3-Second Timer. A countdown appears with audio beeps. Place the phone on your surface during those 3 seconds. At zero, the reading freezes and you get a result card showing the exact tilt in both axes.

This is the most accurate way to measure because the phone is completely still when the reading is taken — no hand tremor, no finger pressure on the screen.

Tap Record Again to do another measurement. Use Calibrate if you want to zero the sensor on a reference surface first.

Frequently Asked Questions

Why a timer instead of just placing the phone down?

Two reasons. First, touching the screen while it's reading can add pressure that slightly flexes the phone, throwing off the sensor. Second, the countdown gives you time to place the phone gently and let it settle — vibrations from putting it down need a moment to die out. The 3-second window handles both.

Can I use this face-down?

Yes. The sensor automatically compensates when beta exceeds 90° (meaning the phone is tilted past vertical or flipped). You can start the timer, flip the phone screen-down on a surface, and it'll still capture an accurate reading.

What do the beeps mean?

Each beep marks one second of the countdown. When the timer hits zero, you'll hear a different tone — higher pitch means level, lower pitch means off-level. If your phone supports vibration, you'll also feel a short buzz at the end. This way you know the reading was captured even if the phone is face-down.

Is the frozen reading more accurate than the live one?

Generally yes, because the phone is stationary. The live reading is filtered through spring-damper physics that smooths out hand tremor, but a still phone on a flat surface gives the cleanest data. The frozen reading is whatever the sensor reported at that exact moment.

How do I compare two surfaces?

Calibrate on the first surface (this sets it as 0°), then move the phone to the second surface and take a timer reading. The result tells you the difference between the two surfaces, not the absolute tilt. Tap Reset to go back to absolute mode.
