PDF, photo and network tools
Free
PDF editing, photo compression, converters, networking and calculations for electronics and 3D printing. 186 tools with no ads and no sign-up.
186 tools in 18 categories: PDF editing, photo compression, converters, a subnet calculator, a filament picker for 3D printing and plenty of small jobs that usually need an app of their own. No ads and no sign-up.
On the first launch the app asks what you do and builds the home screen from the tools that fit. The rest sit in the catalog with a search by name and keywords.
