808 Hub

808 Hub is a focused utility hub that brings together ten daily tools behind one calm, dark interface.

Instead of installing five different single-purpose apps, 808 Hub gives you a single home for the small jobs you do every day: scan a QR code, convert a unit, format a piece of JSON, pick a color, time a task. Every result is saved as a record you can search, tag, pin or favorite, so the tools you use most stay one tap away.

What is inside

QR Code Scan QR codes with the camera or decode them from a saved image. Generate QR codes from any text or URL and save them to your photo library.

Unit Converter Convert length, weight, volume, temperature, area, speed, time, data size and more. Precision arithmetic so the last decimal place is always correct.

Text Tools Change case, count words and characters, encode and decode Base64 and URLs, generate MD5 and SHA hashes, escape and unescape strings.

Calculator Evaluate full mathematical expressions including parentheses, exponents, common functions like sin, cos, log and sqrt. History of past results.

Color Picker Pick a color, see its hex, rgb and hsl values side by side, copy any format with a tap, save palettes for later.

Timer and Stopwatch Run multiple named countdown timers and a precise stopwatch with lap times. Sessions are saved so you can see how long things actually took.

Voice Memo Quick voice notes recorded straight to a local file. Play back later, attach tags, delete when no longer needed.

Tone Generator Generate a clean sine, square, triangle or sawtooth tone at any frequency. Useful for audio testing and ear training.

Image Compress Reduce the file size of photos from your library without leaving the app. Compare before and after, save the smaller version back to your library.

JSON Formatter Paste any JSON and get it pretty printed, minified or validated. Tree view with collapsible sections for large payloads.

One records system across every tool

Every tool run becomes a record you can revisit. Filter records by tool, search by text inside the payload, pin the important ones, attach custom color-coded tags. Save common inputs as shortcuts so a frequent unit conversion or a recurring tone is one tap from launch.

Designed to stay out of your way

Dark theme with a deep blue-purple gradient throughout. No ads, no upsells inside the tools, no tracking of what you convert or scan. The app asks only for the permissions a tool actually needs, the moment you first use that tool, and the in-app explanation tells you exactly why.

Permissions

Camera is used when you open the QR scanner. Photo library is used when you pick an image for QR decoding or image compression, and when you save a generated QR or compressed image back. Microphone is used when you record a voice memo.

No background location, no Bluetooth scanning, no contacts access, no health data, no advertising identifiers.

If you have been looking for one calm place to do the small jobs you do every day, give 808 Hub a try.
