Software that people can rely on
Apps in Zambia run on limited data, shared phones and a lot of trust. We design for that reality and treat security as part of the product, not an extra at the end.
Secure by default
Safe handling of user data, careful dependency choices and sensible permissions from the first commit.
Built for local use
Lightweight apps that respect small data bundles and mid-range Android phones.
Honest engineering
Clear privacy policies, plain language and direct contact with the developer who wrote the code.
Our apps
Android apps designed and built in-house at ZedLab. To try one, message us on WhatsApp and we will send you the app directly.

ZM Utility
A listings app where owners post houses, rooms and land and people can browse and get in touch.
- Browse listings by location and type
- Contact owners directly
- Designed for everyday mobile use in Zambia
Where ZedLab is going
Apps handle more personal data every year, and the people who use them have to be able to trust them from day one. ZedLab is building a security toolkit that Zambian developers can add to their own apps, so they do not each have to solve the same hard problems alone.
ZedLab Secure SDK
A drop-in Android library with safe defaults for the parts that matter most.
- Encrypted local storage for tokens and personal data
- Secure network defaults, including certificate pinning
- Detection of rooted, tampered or emulated devices
- Simple, well-documented API for small teams
App hardening and review
Hands-on security work for Zambian teams shipping Android apps.
- Security review of an existing app and its dependencies
- Fixes for the most common Android weaknesses
- A clear written report in plain language
Sign-in and private data
Reusable patterns for apps that handle accounts and personal records.
- Safe sign-in and one-time-code flows
- Protected storage for personal information
- Audit-friendly logging for sensitive actions
We are designing this in the open. If you build Android apps in Zambia and want to help shape what we make first, get in touch.
How we work
A small studio is able to be careful. These are the rules we hold ourselves to.
Collect less
If an app does not need a piece of data, we do not ask for it.
Fewer, better dependencies
Every library is code we are responsible for, so we choose and update them deliberately.
Say what we do
Our privacy policy is written for users, not lawyers.
Fix, then explain
When something breaks we fix it first and tell users what happened.
About ZedLab
ZedLab was founded by Hamoonga Hikalungu, a self-taught Android developer based in Lusaka with a focus on application security. The studio exists to prove that dependable, well-built software can come from Zambia and be made for Zambians.
Because the studio is small, every message you send is read by the person who writes the code.
