Bubble Level

A bubble level, plumb bob and angle finder in one app — hold your phone against a wall, post or shelf and read the exact tilt in degrees, percent grade or roof pitch. Most level apps stop at a bubble sliding in a tube. PlumbLine adds the tool the trades actually reach for: a digital plumb bob that swings to the side a wall leans and snaps green at true vertical, a two-axis surface check that tells you which edge sits low, and a calibration step that cancels out a slightly bent case so every later reading is honest. WHAT YOU GET - Know instantly whether a wall, post or door jamb is truly vertical, not just "close enough" - Level a shelf, picture frame or rail on the first try instead of nudging and re-checking - See if a worktop, tile or table is flat on both axes, and exactly which edge to shim - Read any slope three ways — degrees, percent grade, or rise-in-12 roof pitch — with no math - Freeze a reading with Hold, so you can lower the phone and still see the number - Keep a timestamped log of every check, so you can prove what was true when you left the job PERFECT FOR - DIYers hanging frames, shelves, mirrors and curtain rails - Carpenters, tilers and finish trades checking jambs, studs and worktops - Homeowners setting fence posts, gates and decking - Anyone who wants a straight result without carrying a spirit level around WHY NOT JUST USE A POCKET SPIRIT LEVEL? A physical level tells you the bubble is "about" centred. PlumbLine gives you the number — 0.4 degrees of lean, low on the right — plus a pass or fail badge against a tolerance you set yourself, and a saved record afterwards. It is already in your pocket, and it never gets left in the van. PRIVACY Everything runs on the motion sensor already in your device. No account, no ads, no tracking, no internet connection needed. Your readings and saved log stay on your phone. FULL ACCESS PlumbLine Premium unlocks the full toolkit — plumb bob, spirit level, surface check, the angle finder with percent and roof-pitch units, fine calibration, and the saved measurement log. Choose a weekly plan, a yearly plan, or a one-time lifetime purchase. Restore Purchases is always available in Settings. Open PlumbLine, press a long edge of your phone flat against the next wall you were about to eyeball, and see how far off it really is. Not for surveying, aviation or safety-critical alignment. Readings are approximate. Terms of Use (EULA): https://web-levi.web.app/terms Privacy Policy: https://web-levi.web.app/privacy-policy Questions? Contact tphuc.work@gmail.com

Verdict
The clearest difference is in-app purchases: UCL App at none against Bubble Level's 3. UCL App also leads on device support (3 vs 1) and iOS requirement (8.0 vs 17.0). Bubble Level's advantage is update cadence (monthly vs every 10 months). On price and ads there is nothing between them.
