# Technical requirements ## Tonomy ID app requirements Tonomy ID uses React Native and supports iOS 13.4 and Android 5.0 (API 21) or newer. See for more details: Additionally, to use the biometric MFA feature on Android, users will need a fingerprint reader on their phone. Apps often give users the option for PIN or Biometrics to work around this. ## Tonomy Gov OS network requirements The Tonomy ID app works when it is supported by the following infrastructure: * [Tonomy Communication](https://github.com/Tonomy-Foundation/Tonomy-Communication/tree/master) service v1.0+ * Tonomy Accounts website from the [Tonomy Apps Websites](https://github.com/Tonomy-Foundation/Tonomy-App-Websites/tree/master) repository v1.0+ * An [Antelope blockchain](https://antelope.io/) network v3.0+ * The `id.tmy` contract in the [Tonomy Contracts](https://github.com/Tonomy-Foundation/Tonomy-Contracts/tree/master) repository deployed to the blockchain v1.0+ See [Deploy Tonomy ID](/run-tonomy-gov-os/deploy.md) for how to run your own network.
