Plumbly: Level, Ruler & Angle

Angle Meter · Inclinometer

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

New: Inclinometer with custom calibration. Turn your iPhone into a precision toolkit — always in your pocket. Plumbly turns your iPhone into a precise, always-available toolkit — no batteries, no bag, no searching. SPIRIT LEVEL Place your iPhone on any surface: table, shelf, picture frame, or floor. The round 2D bubble shows instantly whether it's level. The linear level handles walls and vertical surfaces. The moment you hit ±0°, a short vibration and sound confirm the measurement — no squinting required. RULER Millimeters and inches, side by side, across the full screen length. Exact PPI values are stored for every current iPhone model, so you measure accurately from the very first use. The Pro upgrade adds a manual calibration offset so you can fine-tune the ruler to your device. ANGLE METER Hold your iPhone against any surface, trim, or slope. The angle is displayed live from 0° to 360°. The freeze button locks the current reading — great for awkward positions where you need to move before you can see the screen. INCLINOMETER (Pro) Slope in degrees and percent — with individual calibration so you can define any surface as your zero reference. Useful on construction sites, for setting up shelving units, or checking roof pitches. The built-in compass shows magnetic heading in real time. PRO FEATURES • Inclinometer with ° and % plus compass • Manual ruler calibration offset Unlock all Pro features with a single purchase — no subscription, no recurring fees. NO ACCOUNT. NO SUBSCRIPTION. Plumbly works without registration, without a cloud connection, and without hidden costs. Buy once, use forever.
