7DS Tools
Fifty-eight everyday tools in one app
7DS Tools is an Android app bundling fifty-eight everyday utilities — calculators, converters, document tools and image tools — into a single install. Its value is architectural as much as functional: tools are registry entries rather than screens, so eighteen screens serve the whole catalogue and a new tool costs one file rather than a release cycle.
- 58 tools across 12 categories in one app
- Most work offline; no account needed to start
- Server-driven catalogue — tools update without an app release
Built for a client and shipped on Google Play with 58 tools across 12 categories.
What it does
Capabilities delivered and running for a client.
Registry architecture
Every tool is a data record plus a runner, rendered by one universal shell.
Four execution tiers
On-device, platform plugin, web or server — declared per tool and changeable without a release.
Offline first
Pure calculations run on the device, so most of the catalogue works with no connection.
Document suite
PDF merge, split, compress and convert, handled server-side where it needs to be.
Favourites and history
Local-first with server sync, so a reinstall does not lose your setup.
Guest by default
Usable immediately; signing in upgrades the existing account rather than starting over.
Analytics and crash reporting
Instrumented so problems surface before users report them.
Play Store distribution
Shipped through the full Play review and testing pipeline.
Who it's for
Where this tends to pay for itself.
