How is this ranking scored?

Each company gets 0 to 3 points on six buyer criteria, read only from its own mobile development pages on 2026-11-14. No review-site score, app store rating, partner badge or price is used.

  • 3

    A specific mechanism, for example written acceptance criteria per milestone

  • 2

    A general statement, for example a list of engagement models

  • 1

    Only implied by a separate service, a case study or a marketing line

  • 0

    Not found on the pages checked

The six criteria are: K1 fixed price by milestone with acceptance criteria; K2 model flexibility; K3 AI-native delivery; K4 discovery, consulting or analysis before build; K5 a senior first contact who is accountable; K6 IP and code ownership with no lock-in. A score measures what a company states, not the quality of its apps.

Which kind of mobile app partner do you need?

Option Choose it when Do not choose it when
No-code app builder A prototype or internal app with simple data and few users The app needs custom logic, offline use, push or its own codebase
Freelancer A small, well-defined feature on an existing app Nobody on your side can review code, signing, privacy and release
Native-only studio One platform must use the newest device features first You need both platforms from one budget and one codebase
Large engineering firm A multi-team enterprise programme with regulated data A small product team that needs one accountable contact
Full-stack partner that builds the app and its backend The app depends on a marketplace, commerce or admin API that must be built or changed too You already have a stable API and only need screens

Whether to go native or cross-platform is a separate decision; the native vs cross-platform guide sets out when each fits.

How AI agents change this comparison

With AI agents writing much of the code, delivery capability across these companies is getting closer; the difference is how AI-native the approach is. Netbase integrates AI into every service and builds with AI agents under human review, using the commercial and open-source models chosen per project.

On an Android and iOS build, AI agents can draft API client code, screen scaffolding, unit and UI tests, and review code against agreed standards. Engineers still own the data model, the permissions the app asks for, the signing keys, the store submission and the rollback plan.

  • In delivered work

    Product recommendation engine

    Built for 4over4's online printing store from browsing and purchase history; a delivered AI feature named with a client, on the web store rather than a mobile app.

  • Available capability

    AI agents in delivery

    AI-assisted code and test generation is a capability Netbase offers, not yet tied to a published mobile app case.

How should you choose an Android and iOS app development company?

  1. Decide the platform order

    Android first, iOS first or both at once changes the team, the test devices and the release plan.

  2. List what the app must talk to

    A marketplace API, payment, sign-in providers, push messaging and an admin panel decide whether a screens-only studio or a full-stack partner fits.

  3. Ask for the commercial model in writing

    Fixed price by milestone, time and materials or a dedicated team, and who signs off each milestone against which acceptance criteria.

  4. Ask how AI is used in delivery

    Which steps an AI agent does, and which an engineer reviews before release.

  5. Settle ownership and operations

    Who owns the store developer accounts, the signing keys, the repository and the push service, and who ships updates after launch.

How to verify any company on this list?

Apply the same checks to every company here, Netbase JSC included: confirm the wording behind each score on its site; ask for a reference from an app of your size; ask who writes and signs the acceptance criteria for each milestone; and confirm code ownership in the contract. Ask that the Google Play and App Store Connect accounts sit in your name from day one: both stores support moving an app to another developer account, but on Apple the bundle ID stays fixed once a build is uploaded. The same method ranks the web application, UI/UX design and ServiceNow, Salesforce and Dynamics lists.

What delivery record exists, and what does not?

Market-player facts above are self-published and not audited. Netbase's mobile record is registered work. For RB Marketplace, Netbase built the customer shopping app on the marketplace API: Android, with iOS in the extended scope, push alerts, Google, Facebook and Apple sign-in, checkout through a secure WebView and offline browsing, delivered in six phases from API audit to handover (case). For Dey Page, Netbase built a React Native app for iOS and Android with consumer and business-owner modes, push and deep links (record). No store listing, download count, rating, user number or launch date is claimed for any company here.

Frequently asked questions

No. Netbase JSC wrote this page and ranks itself first on the published criteria; every fact about another company comes from its own site with an access date so a reader can check it independently.

Netbase JSC and Netguru state fixed-price terms on the pages checked; Netbase JSC also states written acceptance criteria for each milestone.

Build both at once when your buyers are split across both platforms and the budget covers two test matrices; otherwise ship the platform most of your buyers use first and keep the API ready for the second.

You should. Keep the Google Play and App Store Connect accounts, the signing keys and the repository in your company's name, and give the development company access rather than ownership.

Every company fact is re-read on its own site at least every 90 days.
