Apps.
Free, installable apps I build and ship — download them directly, no app store required.
Rusty Inbox
Fast, open-source email client in Rust + Qt
Pharmacy Manual
Offline Egyptian drug index & price checker
Real software I build, use and give away
These are the apps Abo-Elmakarem Shohoud builds outside client work: small, focused tools that solve one problem well, ship as real installers, and stay free. Each one has its own page with screenshots, the current version and a direct download.
Rusty Inbox is a desktop email client for Linux, Windows and macOS. Its engine is written in Rust and its interface in Qt 6 / QML, so it opens instantly, stays light on memory and keeps mail on your machine with no telemetry. It is open source on GitHub.
Pharmacy Manual (دليل الأدوية الإكلينيكي) is an offline Android drug index for Egypt, built with Flutter. It covers more than 24,868 medicines searchable by Arabic or English name and active ingredient, shows cheaper same-ingredient alternatives and prices, and works with no internet connection, which is what pharmacists and doctors in Egypt actually need at the counter.
How the apps are built
The stack is chosen per problem: Rust and Qt for a fast native desktop app, Flutter and Dart for a single Android codebase with a local offline database. Each app ships as a real installer, and the download buttons on these pages always point to the latest published version.
The same engineering approach is behind the production SaaS products Karem leads as CTO at Ailigent: Tornix.ai, Oravex.app and Costra.
