Mobile app development in Nigeria

Eltemur Zentra Studio builds mobile applications when the product belongs on a phone. Shipped work includes an offline Android app and an Android companion for a product that also runs on the web and Windows.

Who it is for

  • A product that people will use away from a desk.
  • A tool that must keep working without a connection.
  • A SaaS product that needs a phone app beside the web version.

Problems it solves

The task happens on a phone

If the person is not at a computer, a mobile app is the practical place for the workflow. GradeNG is an Android app for checking CGPA on the phone.

The work has to continue offline

GradeNG stores semesters and courses on the device, so a student can update a record without a connection.

The phone app and the web product are separate accounts

Scoutier uses one account across web, Windows, and Android. The Android app is part of the same product, not a second database.

What Eltemur Zentra Studio can build

  • Android applications. GradeNG is a Flutter app, and Scoutier is on Google Play.
  • Cross-platform applications where one product already covers web and Android, as Scoutier does with Capacitor.
  • Companion apps for a product that also has a website.
  • Business and education tools that belong on a phone.
  • Deployment support for a Play listing when that is part of the scope. GradeNG does not have a public store link listed yet.

Main deliverables

  • A mobile scope: the task, the platform, and whether it must work offline.
  • The app screens for that task.
  • An installable Android build.
  • Store listing support when a public Play release is in scope.
  • A handover covering how the app is updated.

How this work runs

  1. 01 Discovery

    We confirm the phone task, whether Android is the platform, and whether the app must work offline.

  2. 02 Planning and design

    We map the screens at phone size, including the empty state and the record the person is trying to keep.

  3. 03 Development and testing

    We build the app and test it on Android. Where the product also has a web or desktop version, we test that the account or data behaves as scoped.

  4. 04 Launch and support

    We help ship the build and stay available for fixes after release.

Questions

Does Eltemur Zentra Studio build Android apps?

Yes. GradeNG is an offline Android app for CGPA calculation. Scoutier also has an Android app on Google Play, beside its web and Windows versions.

Do you build iPhone apps?

No iOS app is listed in the completed work. The shipped mobile work is Android: Flutter for GradeNG, and Capacitor for Scoutier.

Can the app work without internet?

Yes, when that is the point of the product. GradeNG is offline and can export a JSON backup. A connected product, such as Scoutier, uses the network for the account.
