devbench is a native developer toolbox for iPhone, iPad, and Mac. Thirty focused tools in one app, every one running entirely on device. No accounts, no network, no tracking.
Instead of juggling sketchy web utilities and pasting sensitive data into random sites, keep your everyday dev tools in one fast, private, offline app that works the same across all your Apple devices.
