Calibrate once against any known-flat surface, and every reading after that — on every job — stays accurate. No guesswork, no drift, no second-guessing your tools.

WHAT YOU GET FREE
• Surface Level — a classic bubble level for flat surfaces, screen up
• Edge Level — a plumb / vertical level for walls, frames, and studs
• Instant calibration against any reference surface you trust
• Light, dark, and system theme support

UNLOCK FOR $1.99 — ONCE, NO SUBSCRIPTION
• Slope % — grade readings in degrees and percent, for drainage, ramps, and grading work
• Project Log — save labeled readings with timestamps and photos
• CSV export — turn saved readings into a client-ready report

BUILT LIKE A TOOL, NOT AN APP
Precision Spirit Level fuses accelerometer and gyroscope data through a tuned complementary filter for a stable, drift-resistant bubble — then lets you zero it out against a surface you trust. That's the whole idea: calibrate once, trust every reading.

OFFLINE. NO ACCOUNT. YOUR DATA STAYS ON YOUR PHONE.
No sign-up, no login, no internet connection required. Every reading, calibration offset, and saved log entry stays on your device — nothing is ever uploaded, tracked, or sold.

WHO IT'S FOR
Carpenters, framers, tilers, landscapers, plumbers, and anyone who needs a reliable digital level, angle finder, or inclinometer on the phone already in their pocket.

$1.99 once. No subscription, no ads, no artificial free-tier limits designed to nag you.
Calibrate once. Trust every reading. ## Rankings - #2,885,030 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `android.permission.VIBRATE` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.precisionspiritlevel.app.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [ProLevel - Precision Level](https://chrome-stats.com/d/com.tonybytes.prolevel) — 14 users - [Bubble Level: Angle & Pitch](https://chrome-stats.com/d/com.tomas.bubble_level_inclinometer) — 1,081 users - [Level — Spirit Level & Angle](https://chrome-stats.com/d/com.owlmakers.bubblelevel) — 20 users - [Precision Bubble, Spirit Level](https://chrome-stats.com/d/com.boulla.bubblelevel) — 161,318 users, 4.15 / 5 - [Easy Level](https://chrome-stats.com/d/cl.easysoft.easylevelapp) — 33 users - [Bubble Level & Inclinometer](https://chrome-stats.com/d/com.play3rs.bubblelevel) — 36 users - [Bubble Level](https://chrome-stats.com/d/com.cpl.bubblelevel) — 42 users - [Sweet Bubble: Bubble Level](https://chrome-stats.com/d/com.sweetpethouse.sweetbubble.bubblelevel) - [A-Level: Bubble & Spirit Tool](https://chrome-stats.com/d/a.bubblelevel.spiritpro) — 64 users - [Bubble Level Pro](https://chrome-stats.com/d/com.shradhacreative.bubblelevel) — 414 users - [Spirit Level: Bubble & Angle](https://chrome-stats.com/d/com.suterazisi.watercal.yenihizliwater.suterazisi) — 33 users - [Bubble Level: Spirit Level](https://chrome-stats.com/d/com.cordevs.bubblelevel) — 30 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.precisionspiritlevel.app)
