Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteChoose a React Native development company by testing how it will handle your app’s native integrations, framework and dependency upgrades, performance measurement, and data security—not by accepting a technology pitch or a generic portfolio. Ask candidates to explain those decisions against your requirements, then request concrete evidence such as a technical design, dependency inventory, data-flow explanation, and relevant shipped work.
Start with the work your app actually needs
React Native lets JavaScript application code connect to platform APIs and native views through native modules and native components. The right partner should be able to explain which parts of your proposed app can remain shared and where iOS- or Android-specific implementation may be needed.
Ask the company to map your requirements—such as platform APIs, device capabilities, or custom interface elements—to the proposed implementation. Request a walkthrough of relevant shipped work and a technical design showing the boundary between shared JavaScript and native code. A credible answer should distinguish using an existing library from writing or maintaining native code, and explain who will own that code over time.
React Native’s native platform guidance describes the roles of native modules and native components. It also notes that legacy module APIs are deprecated; depending on the case, a team may recommend alternatives, upgrading to a library with first-class support, or porting to Turbo Native Modules and Fabric Native Components. Ask how any proposed integration fits the versions and libraries in your project.

Ask for a version-specific architecture and upgrade plan
Do not treat “supports the New Architecture” as a complete answer. The React Native architecture documentation says the New Architecture was enabled by default in React Native 0.76, while warning that enabling it does not necessarily improve an app’s performance or user experience immediately. Application code may need refactoring to use the new capabilities, and serialization may not have been the app’s bottleneck. Ask what the team will measure and change, rather than accepting an automatic speed-gain claim.
Architecture defaults depend on framework version. React Native’s architecture page identifies 0.76 as the version where the New Architecture became the default. Expo’s guide says React Native 0.82 removed the option to disable it, Expo SDK 54 was the last SDK version where disabling it was possible, and SDK 55 uses React Native 0.83. These are version-specific statements; confirm the official guidance for the versions being proposed when you negotiate and when work begins.

Require a dependency inventory and upgrade plan tied to the selected React Native or Expo versions. Expo recommends checking library compatibility and warns that some third-party libraries may require updates or changes. The plan should name dependencies that are unsupported or uncertain, explain how compatibility will be verified, and identify how upgrades and migration risks will be handled.
Evaluate performance claims with measurements
A framework architecture is not a performance result. Ask the company to identify the relevant user-facing performance requirements, establish a baseline, and propose target measurements for the actual app. Then ask which bottleneck each proposed change is expected to address and how the team will verify the result.

- What You Get: Anker USB-C Hub (7-in-1), welcome guide, 18-month warranty, and our friendly customer service.
- Request measurements tied to your app’s requirements rather than a general claim that a framework version is faster.
- Ask how the team will distinguish a JavaScript, native, network, or other bottleneck before choosing an intervention.
- Have the company explain why its proposed architecture or dependency change is expected to affect the measured issue.
This approach follows React Native’s caution that the New Architecture may require application refactoring and may not help when serialization was not the bottleneck.
Make security and data handling explicit
Ask for a data-flow explanation that distinguishes public app configuration from secrets, identifies what is stored on the device, and describes what is sent to your servers. React Native’s security guide states, “Never store sensitive API keys in your app code.” A secret included in an app bundle can be inspected; when an app needs a secret to access a resource, the guide recommends using a server-side orchestration layer.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
For persisted data, ask the team to classify what is sensitive and choose storage accordingly. The guide describes Async Storage as an asynchronous, unencrypted key-value store: it can suit non-sensitive persisted data, but not tokens or secrets. It identifies platform-specific secure storage options including iOS Keychain Services and Android Keystore. Ask where access tokens and other sensitive values will live, and how the implementation’s choice matches the data’s sensitivity.
For network traffic, ask how APIs use SSL encryption and what threat model informs any additional controls. React Native describes certificate pinning as a possible client-side technique, but it creates an operational obligation: embedded certificates must be updated when server certificates change. Treat pinning as a decision with maintenance costs, not a universal security checkbox. See the React Native security guide.

Use a focused vendor interview
The following prompts turn technical documentation into practical evaluation questions. They are a starting point, not a validated weighted scorecard; weight each area according to your app’s native features, data sensitivity, existing codebase, and in-house maintenance capacity.
| Area | Ask the company | Evidence to request |
|---|---|---|
| iOS and Android integration | Which requirements need native APIs, modules, or views? How will those integrations be maintained? | A relevant shipped-work walkthrough, technical design, and clear boundary between shared JavaScript and native code. |
| Architecture and dependencies | Which React Native or Expo versions and libraries does the design require? How will compatibility and upgrades be checked? | A dependency inventory and version-specific migration or upgrade plan that flags risks and unsupported modules. |
| Security and data handling | Where will API credentials, access tokens, and persisted user data be stored? What leaves the device? | A data-flow explanation distinguishing configuration from secrets, sensitive from non-sensitive storage, and HTTPS-protected traffic. |
| Performance | What measurements identify the bottleneck, and what change is expected to improve it? | Baseline and target measurements connected to your app’s requirements. |
Compare proposals on evidence, ownership, and fit
Ask each finalist to answer the same technical questions against the same requirements. Compare the specificity of the proposed design, whether risks are named rather than hidden, and whether the team explains ongoing maintenance—not just initial delivery. A proposal should make clear who owns native integrations, dependency upgrades, security decisions, and measurement after launch.
The official technical sources cited here explain React Native capabilities and version or security considerations; they do not establish agency rankings, rates, contract terms, geographic availability, or provider outcomes. Treat a vendor’s credentials and commercial claims as matters to verify directly, rather than inferring them from framework documentation.
