About Level
Level turns your iPhone or iPad into a precise digital spirit level. A heavy, machined-aluminium look frames a glowing bubble vial that behaves just like the real thing — set your phone down and the bubble settles, drifting toward the high side so you can see exactly how far off true you are.
Lay the device flat for a two-axis bullseye that reads pitch and roll together, or stand it on its side and switch to Edge mode for a classic single-axis bar level. Big, easy-to-read degree readouts update live as you move, so hanging a shelf, leveling a washing machine, or checking a picture frame takes seconds.
📐 Built for accuracy: Calibrate to any reference surface in a single tap, then lock in a reading with Hold and reset your zero whenever you like. Optional sound and haptics tell you the moment a surface is truly level — no need to keep staring at the screen.
Level runs in landscape so the bubble and readouts get the full width of your display, and the whole interface is tuned for a quick, confident glance. It's free to use, with a single optional in-app purchase to remove ads and support development.
How It Works
Getting a true reading takes just a few taps:
Place Your Device
Lay the phone flat on a surface for the bullseye level, or stand it on an edge against the object you're checking for Edge mode.
Read Pitch & Roll
Watch the bubble drift toward the high side while large numeric readouts show the exact tilt in degrees on each axis.
Calibrate & Hold
Tap CAL to zero the level against a known-flat reference, then use Hold to freeze a reading so you can move and check it.
Know When It's Level
Turn on sound and haptics to get a clear cue the instant the surface lands within your chosen tolerance.
Features
🎯 Bullseye Level
A glowing, true-to-life bubble vial measures pitch and roll at once — perfect for tables, shelves, appliances, and tripods.
📏 Edge Mode
Stand the device on its side for a classic single-axis bar level when you're checking a picture frame, post, or doorframe.
🔢 Live Degree Readouts
Large, glanceable pitch and roll values update in real time, with adjustable sensitivity from low to high.
🎚️ One-Tap Calibration
Calibrate to any reference surface so a flat tabletop reads a true 0.0° — and reset to factory zero anytime.
🔒 Hold & Reset
Freeze the current reading with Hold to capture a hard-to-see angle, then reset your zero with a single tap.
🔔 Sound & Haptics
Optional audio and haptic feedback signal the moment a surface is level, so you don't have to watch the screen.
⚙️ Tunable Tolerance
Set how strict "level" is and choose whether the bubble drifts to the high side, matching how a real spirit level behaves.

Privacy Policy
Last updated: June 2026
1. Introduction
This Privacy Policy describes how Level ("the App," "we," "our," or "us") handles information. The App uses your device's motion sensors to act as a digital bubble level and inclinometer.
We respect your privacy. This policy explains what data the App and its service providers process, and what stays on your device.
2. Sensor Data Stays on Your Device
The App reads your device's accelerometer and motion sensors only while it is open, solely to calculate tilt, pitch, and roll for the on-screen level.
- Motion and orientation data is processed entirely on your device in real time and is never recorded, stored, or transmitted to us or anyone else.
- Any calibration offset you set is saved only on your device.
- The App does not require an account or registration.
3. Advertising
The free version of Level displays ads through Google AdMob. To serve ads, AdMob may collect and process certain information, such as a device advertising identifier, general device and usage data, and approximate location derived from your IP address.
You can review Google's practices here: Google Ads & Privacy. The Remove Ads purchase removes all ads.
4. App Tracking Transparency
Where required, the App asks for your permission via Apple's App Tracking Transparency prompt before any data is used to deliver personalized ads. If you decline, ads remain non-personalized. You can change this choice any time in Settings → Privacy & Security → Tracking.
5. In-App Purchases
The Remove Ads upgrade is processed by Apple through the App Store. We do not receive or store your payment details. Purchase validation and restoration are handled by Apple's StoreKit.
6. Children's Privacy
The App is not directed at children under 13 and does not knowingly collect personal information from them. The advertising described above is provided by third parties subject to their own policies.
7. Changes to This Privacy Policy
We may update this Privacy Policy periodically. Any updates will be reflected on this page with a new "Last Updated" date.
