Developer Tools for Android

Developers constantly switch between small utilities — encoding a string to Base64, testing a regex pattern, decoding a JWT to check its claims, converting a hex color to RGB. DevBuddy brings all of these into a single Android app so you're not juggling browser tabs or hunting for a reliable online tool every time you need something basic.

The regex tester is interactive: type your pattern and test string, and matches highlight in real time. You can toggle flags (case-insensitive, multiline, dotAll), see capture groups labeled separately, and copy the match results. It's the same experience as regex101.com but on your phone without an internet connection.

JWT decoding is immediate — paste a token and DevBuddy splits it into header, payload, and signature. The payload JSON is formatted and displayed with expiry times converted to human-readable dates. This is useful when debugging auth issues on a mobile API or checking token claims from a test environment.

Hash generators cover MD5, SHA-1, SHA-256, and SHA-512. Base64 encoding and decoding handles both standard and URL-safe variants. The color picker converts between HEX, RGB, HSL, and HSV with a visual color wheel. Every tool is reachable from the home screen in one tap, with no ads interrupting the workflow.
