Solving real problems with technology people can afford
Hadtah began in a classroom. Our founder, Kisitu Ahmed, is a teacher in Kakiri, Wakiso, Uganda. Every day he saw problems that simple software could solve: libraries run on paper, small shops that did not know their profit, students losing hours to their phones, and families losing money to scam messages.
Each Hadtah app started as one of his ideas for solving those problems, and we build them for real conditions: low-cost phones, shared computers, expensive data and power cuts. Most of our apps work with no internet at all, and they keep your information on your own device.
The name comes from the Aramaic hadta, meaning “new” or “renewed”.
Our mission
To solve real problems in our communities with affordable, offline-friendly technology that works for people in Uganda and across Africa.
Our vision
An Africa where every learner, teacher, school and small business has simple, dependable digital tools, whether or not they have fast internet, a new phone or money to spare.
Works offline
Built for power cuts and costly data. Most apps need no internet after you install them.
Affordable
Our apps are free. Where something costs money, we say so clearly up front.
Private by design
Your records stay on your device. No ads, and no selling your information.
Made for here
Ugandan curriculum, UGX, Mobile Money and local scams, designed with local users in mind.
What’s new at Hadtah

Questions people ask
How do I install an Android APK?
- Press Android APK under the app. The file is saved to your Downloads.
- Open the file from your notifications or the Files app.
- If your phone says installs from this source are blocked, tap Settings, turn on Allow from this source, and go back.
- Tap Install, then Open.
This is normal for apps that do not come from the Play Store. Only install APKs downloaded from this website.
Windows says “Windows protected your PC”. Is it safe?
Yes. This SmartScreen message appears for new apps that do not yet have a paid code-signing certificate. Click More info, then Run anyway, and continue the installer. Download installers only from this website.
How do I put an app on my iPhone?
- Press Open on iPhone. It opens the app in Safari.
- Tap the Share button (the square with an arrow).
- Scroll down and tap Add to Home Screen, then Add.
The app now has its own icon on your Home Screen. Ennun and Lamma also have a website you can add this way. Eilpah needs an iPhone 6s or newer (iOS 15 or later); live classes work best on newer iPhones.
What happens to my data? Is it private?
Ennun, Lamma, Offline Library and Cash Flow save everything on your own phone or computer. Nothing is sent to us. Use the backup option in the app to keep a copy. TTu and Eilpah are online services: they keep your account and what you need to use them, and nothing is sold or shared for advertising. See our Privacy page.
Do the apps cost money?
Eilpah, Ennun, Lamma, Offline Library and Cash Flow are free. TTu is free for 20 questions a day and 20 PDF downloads; after that there is an optional weekly plan, shown clearly in TTu before you pay. Free during launch until 15 Dec 2026: all Hadtah apps, including TTu and Eilpah, need no payment or subscription until then.
Do I need internet?
Not for Ennun, Lamma, Offline Library or Cash Flow once they are installed or opened once. TTu and Eilpah need internet. The Ask TTu button in each app needs internet and shows “Needs internet” when you are offline.
What is the “Ask TTu” button?
It opens TTu, our question-and-answer app, in a panel without leaving the page. If sign-in does not work inside the panel on your browser, use Open in new tab.
