Questions, answered
Is Toolshop4u really free?
Yes. All 168 tools are free to use with no locked features, accounts or subscriptions. The app is supported by unobtrusive ads that never interrupt a running tool.
Do the tools work offline?
Almost all of them, yes — compression, conversion, formatting and calculators run entirely on your phone. Only network tools (DNS lookup, ping, SSL check…) need a connection, for obvious reasons.
What happens to my files?
Nothing leaves your device. Files are processed locally in the app and are never uploaded to a server — there isn't even a server to upload them to.
Which platforms are supported?
Android first, with iOS following shortly.
What makes it different from other tool apps?
Everything is built for mobile: fast launch, offline support, native file save & share, and a home screen that learns which tools you use most.
