A tab with an advert may open when you tap download. Close it and come back here to carry on — those clicks are what keep TechBigs free.
Before you install
- When Android refuses the install, it is the unknown-sources guard doing it. Grant this app permission in Settings, then confirm the install when the prompt comes back.
- An "incompatible version" message usually means the build was compiled for the older ARMv7 processors that recent phones no longer accept. Look for the ARM64 (ARMv8) build of the same version instead.
Download FAQs
What is DevToolKit Developer Tools used for?
DevToolKit Developer Tools is a developer-tools app for testing regex patterns, formatting JSON, decoding JWTs, handling timestamps, and encoding Base64 images. Its tools also cover JSON error locations and sharing large encoded image results as files.
What does Premium Unlocked change in this build?
Premium Unlocked is the MOD label for this build. DevToolKit Developer Tools continues to include the documented regex, JSON, JWT, timestamp, and Base64 image utilities.
How does the JSON formatter handle errors and numbers?
The JSON formatter reports errors with both a line and column. It keeps numbers exactly as written during formatting.
Which timestamp formats can DevToolKit Developer Tools handle?
Timestamps can include time zone offsets. They can also include fractional seconds.
What changed in version 1.0.4?
Version 1.0.4 updates the regex tester so slow patterns no longer freeze it and every match is highlighted. It also corrects expired JWT handling and changes Base64 image encoding to use the original file, with large results shareable as files.
Nothing happens when I tap download
Refresh the page and start again — each link is signed for one visit and stops working after that. If it keeps failing, the file is probably being swapped for a newer build; give it a few minutes.
Android says "App not installed"
Usually there is already a copy of the same app on the phone, signed by someone else. Remove that copy first, then install this file — and back up anything you care about inside the app beforehand, because uninstalling wipes it.
