Handcrafted-silver jewelry catalog sold by weight: a dark-luxury storefront with filters by finish and weight, WhatsApp ordering by total grams, and a bilingual admin panel with Excel import.
An intermittent fasting tracker for Android and iOS: a timer that stays right when the app is closed, a body-stage timeline, water, weight and hunger logging, Health Connect sync and a configurable home-screen widget. In beta.
Our own self-hosted remote-support platform (RustDesk OSS): one-click download that already knows our relay server, so we can assist customers on their own machine without third-party tools.
Built to be used every day
Intermittent fasting tracker: a timer that survives a reboot, the body-stage timeline, water, weight and hunger logging, Health Connect sync and a home-screen widget you choose the metrics for. Screening questions come before any plan is suggested — the app is built to tell you when not to fast.
Prayer times in your taskbar — or in the Mac menu bar — with a daily schedule panel, adhan playback, expiry reminders and a full-screen screensaver. Worldwide city database — over 34,000 cities. Installs and updates itself silently.
Mac — one line in Terminal:
curl -fsSL https://mejelsoft.com/mac | bash
Reading companion for the Cevşen prayer collection with Arabic text and translation, section navigation, distraction-free reading and offline worldwide prayer times.
Remote support for our customers. One file, no installation: run it and read us the number on your screen. The session runs end-to-end encrypted through our own server — nothing passes through a third-party cloud, and access ends when you close the window.
Installers are unsigned — Windows SmartScreen and Android may warn on first run. Choose More info → Run anyway, or install from a store build once published. On a Mac the single command above does everything — it picks the right build, installs it and signs it on your own machine (setup guide).
