Peter Piekarczyk@peterpmeExpo is amazingAdnan@adnansahinovichReact Native and @expo is the best option by far, and can’t even compare to Xamarin or Dart & FlutterNicoDevs@Nico_DevsI love @expo, it made React Native dev so much easier. Firstly, it allows anyone to dev from any machine, even with very low specs and run the app on device with Expo Go app.Also, it includes so many libraries and the performance is crazy especially on Expo SDK 54 Nana Asante@asantenocturnalI love expo Antonin marchard@antomarchardThe more time flies, the more I love @reactnative & @expo Adrian Carolli@icookandcodeI love @expo for making my life so much easier!Simon Grimm@schlimmsonIt's almost shocking how much I take Expo API routes for granted at this point.I can't imagine working any other way, they are a natural part of every RN project I do.Hugo Duarte@hugoasduarteI love @expo so much!Was struggling to upgrade an old React Native app to the latest version for a few days without success.Created a new expo app, copied my src folder along with some package installs and was ready in just a few minutes!devon@devon_94highly recommend @expoJD Conley@wackieif you're debating between raw react native and expo, choose expo. i tried years ago but it wasn't good enough. now the wrapper is winning. smooth dev environment. flexible. much better ecosystem and documentation.Melih Yumak@hadnazzar? Why choose #Expo for your next app? Enjoy the simplicity of building with one codebase for all platforms, access a rich library of pre-built components, and streamline updates with over-the-air changes—all without touching native code! ? #ReactNative #js #100DaysOfCode:) waally@_mohawwalI love expo/react nativeJosh Gonsalves@joshgonsalves_Makes sense. I do LOVE expo.miaugladiator11@miaugladiator1can 100% recommend expo is so much better than just pure react native imoDane Grant@danecandoAlso, @expo is amazinggetDerivedSwaggerFromHacker@hackerswaggerBig enterprise app guy here. Expo is the best! In the time another team experimented with all the new repack module federation nonsense I've got our two apps using expo CNG and almost done with new architecture. We have a mini app architecture and it's a pain.Prince Ajuzie@princeajuzie7dude, react native + expo is the best option out there.Patrick Aljord@patcitoJust use @expo

[H2] Data security and privacy
[H3] End-user data
Expo Application Services involve building and distributing your application code, not your application data. Thus, Expo is not aware of your users' identities and does not store or handle PII related to your users. You can read more about the data we collect and how we handle it in our Privacy Explained document.
[H3] Data encryption
Data is encrypted in transit and at rest. Expo uses modern TLS to encrypt data in transit and encrypts data at rest using industry-standard encryption algorithms, including AES-256 or greater.
[H3] Data retention
EAS Build workers are ephemeral servers, which are cleared after each use, and use a fresh image on each build, ensuring your application source code is not exposed to another account's build job. EAS Build logs and artifacts are stored for 90 days before being deleted. Backups are deleted 90 days after they are created.
[H3] Data removal
User data is deleted immediately upon deletion of a user profile or account. To ensure they are authorized to do so, users must delete their accounts from within the Expo user interface. Once a user profile or account is deleted, a job is initiated to delete any corresponding records stored by a subprocessor.
[H3] Best-in-class cloud infrastructure security
Expo services are primarily hosted on Google Cloud Platform, providing best-in-class physical and logical security. You can read more about Google Cloud Platform's security practices here.

[H2] Application security
[H3] Multi-factor authentication
Individual user profiles can enable multi-factor authentication (MFA) to add an extra layer of security to their accounts. MFA requires users to provide two or more verification factors to access their accounts, a time-based one-time password (TOTP) or backup key to be provided when logging in, in addition to a password. Additional factors are also required when logging in via the Expo or EAS CLI.
[H3] Single sign-on
Enterprise subscribers can integrate their existing identity provider (IdP) with Expo for seamless authentication. This allows team members to use their organization's SSO credentials to access Expo Application Services, simplifying access management and enhancing security through centralized authentication controls.
[H3] Audit logging
Audit logs of administrative activities are available for Enterprise subscribers. These logs include information about users added and removed, API tokens generated, changes to build and deploy credentials, and other actions.

“As of today, the only recommended community framework for React Native is Expo.”Nicola CortiSoftware Engineer“I used to tell people: use Expo to start fast. Now I just say: use Expo. Period. ”Dan TamasSoftware Engineer“Choosing React Native, Expo, and a shared codebase allowed us to keep complexity down while delivering real value fast.”Paul BricklesEngineering Manager“Expo transformed our release strategy from a cumbersome 3-week cycle to a streamlined weekly release schedule. This accelerated our responsiveness to user feedback and market demands.”Steve GaliliLead Software Engineer“Expo Workflows replaced our sluggish and brittle build process with something quick and dependable. Expo allows our engineers to focus on building features and not debugging build logs.”Armaiz AdenwalaSenior Software Engineer“Expo is most effective way to build mobile apps today. The large ecosystem, smooth DX, great documentation, vast array of 3rd party libraries, EAS services, & superb customer support are first class.”Jamon HolmgrenCo-Founder & CTO
