Mobile app development

Cross-platform mobile apps — agent speed, engineer judgment

Mobile app development in Tanzania with mobile money and offline support

iOS and Android with M-Pesa, Tigo Pesa, Airtel Money, and offline-first design for East African networks. Agents accelerate scaffolding; engineers own architecture, reconciliation, and store release — typically 6–10 weeks for an MVP.

What we build

Mobile apps for field teams, customers, and payments

Built for mid-range Android devices, intermittent data, and the payment rails Tanzanians actually use.

Cross-platform (default)

One React Native or Flutter codebase for iOS and Android — faster delivery when both stores matter.

Native when needed

Kotlin or Swift for deep device APIs or performance-critical modules — we recommend this only when it earns its cost.

Mobile money integration

M-Pesa, Tigo Pesa, and Airtel Money with callbacks, reconciliation, and failure handling — via aggregators or direct APIs as your compliance needs require.

Offline-first apps

Local storage, sync, and conflict handling for teams outside reliable fibre coverage.

Field operations

Delivery, inventory, and data collection with GPS, camera, and push notifications where useful.

Customer-facing apps

Booking, ordering, and self-service — including Swahili/English labels and careful data use on low-end devices.

Why Oltana

Ship mobile for Tanzanian networks — without black-box store releases.

  • 01

    Mobile money done properly

    Collections and disbursements with reconciliation — not a demo STK push that fails in production.

  • 02

    Offline and low bandwidth

    We design for how phones are used outside city centres: sync later, stay usable now.

  • 03

    You own the store accounts

    Apple and Google listings stay under your organisation. We publish from your credentials.

  • 04

    Human gate before release

    We aim for smooth interaction on target devices — and we validate on real mid-range hardware, not marketing claims alone.

Assisted Engineering

Human-led. Agent-accelerated.

For iOS/Android in Tanzania: agents accelerate screens and sync layers; engineers own offline strategy, payments, and store release.

  1. Decide

    Choose cross-platform vs native, offline needs, and payment rails. Engineers decide; agents research options.

  2. Build

    Weekly builds. Agents speed shared UI; engineers own sync, money flows, and device edge cases.

  3. Verify

    Device and payment testing on real networks. Humans accept or reject before store submission.

  4. Ship

    Store submission from your accounts, plus a maintenance plan for OS updates.

What you get

From build to store — still accountable

One codebase, two platforms

Ship to App Store and Play Store from React Native or Flutter when that fits.

Mobile money built-in

M-Pesa, Tigo Pesa, Airtel Money with reconciliation — not a bolt-on.

Offline support

Work without internet, sync when connected.

Push & device features

Notifications, camera, and GPS when the workflow needs them.

App store ready

Submission, screenshots, and compliance from your developer accounts.

Ongoing maintenance

OS updates, crash fixes, and feature sprints after launch.

Pricing

Engagement models, not fixed catalogue prices

Every build is different, so these are starting structures — your final quote is scoped to what you actually need.

FAQ

Mobile app development Tanzania — common questions

How much does it cost to build a mobile app in Tanzania?

Cost depends on features, mobile money integrations, and offline requirements. Focused cross-platform MVPs typically start from TZS 6,500,000 and take 6–10 weeks. We confirm a written estimate after discovery.

Who owns the Apple and Google developer accounts?

You do. We set up and publish from your accounts so you keep full control of the listings, credentials, and revenue.

Should I build a mobile app or a web app?

If users work offline, need camera or GPS, or collect payments on the go, mobile is usually better. Otherwise a progressive web app may be faster and cheaper — we help you choose.

Can you integrate mobile money into our app?

Yes. We integrate M-Pesa, Tigo Pesa, and Airtel Money for payments, collections, and disbursements — including callbacks, reconciliation, and failure handling. This is a core capability, not a bolt-on.

Do you build native or cross-platform?

We usually recommend React Native or Flutter so one codebase ships to both stores. We recommend native Kotlin or Swift when you need deep platform APIs or performance-critical modules.

How do you handle offline functionality?

We design offline-first where needed — local storage, background sync, and conflict resolution — so field teams keep working without reliable internet.

Do you provide maintenance after launch?

Yes. OS updates, store compliance, crash fixes, and feature sprints are available so the app stays healthy after release.
