Bubble Level Tool - Digital lets you see the current angle of your device, along with reseting and locking the angle too. Tilt the device to measure the precise angle and easily switch between portrait, landscape & surface level. If you have any questions or feedback, I'm all ears. Bubble Level Tool - Digital was created by an individual in his free time, and I’d love to know what you think. I’m available through Twitter @elohohel & Mastodon @[email protected].
