About this app

Offline Toolbox puts 45 tools in one app — ruler, bubble level, compass, sound meter, unit converter, QR scanner and more. Every tool works offline, no internet needed.

Your phone already has the sensors. You just need the tools. Instead of installing a separate app for every measurement, conversion and calculation, keep all 45 in one place — and stop waiting on a signal that never arrives in a basement, on a plane, or out on site.

📏 MEASURE WITH YOUR PHONE
- Ruler — measure small objects right on your screen
- Bubble Level — a spirit level for hanging shelves and frames straight
- Protractor — read angles without a physical tool

- Light Meter — measure ambient brightness in lux
- Speedometer — GPS speed for walks, rides and drives
- Altimeter — altitude on devices with a barometer

WHAT MAKES THIS TOOL BOX DIFFERENT
An all in one toolkit where every one of the 45 tools runs entirely on your device. No sign-up, no account, no sync, no waiting for a connection — open it in airplane mode and everything still works.

Ads support development and use a connection when you have one. The tools themselves never do.

Built on Material You, so the utility toolbox picks up your wallpaper colours and follows your dark mode. Available in 12 languages.

Handy for the DIY beginner hanging a first shelf and the handyman measuring on site. Useful for students who need a protractor and a scientific calculator in the same place, and for travellers converting currency and measurements abroad.

🔧 REAL SITUATIONS
- Hanging a picture and needing a level right now
- Checking a shelf is straight before you drill
- Converting currency on a flight with no signal
- Comparing unit prices in the supermarket aisle
- Working through geometry homework without a protractor
- Estimating fuel cost before a long drive

⚙️ ALSO INSIDE
- Home screen widget with six tool slots you pick yourself
- Long-press the icon for four shortcuts to your top tools
- Favourites, recents and search across all 45 tools
- Light and dark themes, both properly tuned

🔒 PRIVACY AND PERMISSIONS
Permissions are requested only when a tool needs them, and only for that tool. Camera powers the magnifier, night vision, mirror and QR scanner. Microphone lets the sound meter read levels — no audio is recorded or stored. Location gives the speedometer GPS speed. Nothing you measure, type or calculate leaves your phone.

Install Offline Toolbox and get 45 everyday tools that work anywhere, connection or not.

One tool box, 45 tools, no internet required.
