How to run?

This app is built with expo (a wrapper for react-native). To run this app, first you need to install expo-cli

yarn global add expo-cli

Now, clone the repo and do these:

git clone
cd InstaNotary

To run the android app, you can directly download the app from Release, I have app in both apk and bundled form. Or, if you want to run from the repo, you have to first download the expo app in both android play store and ios app store, then you can follow these steps:

cd InstaNotary
expo start //This will open a window in http://localhost:19002

Now you have to open expo app in android and ios and scan the QR code from the metro bundler in http://localhost:19002 ,You will be able run the app now.

How to Build?

Be sure to update the versions (for each of Android and iOS) in app.json in the root, between build updates.

You can build the app using expo commands:

  • For Android
expo build:android -t apk // for building apk
expo build:android -t app-bundle // for building bundle

These commands directly build your app but you have to create an account on expo. Also for more details regarding building for android you can follow this doc Expo Android Build Doc. This has a step by step instructions to build your app.

Once done, if you want to push to the Google PlayStore, use:

expo upload:android
  • For IOS

If building with XCode, first do the following on a newly installed copy of the code, in the ios folder:

pod install

In XCode, be sure to set the correct development team account:

Build Setting - Signing - Development Team - Change The Account "S3LY459S86"
expo build:ios -t archive // for app store
expo build:ios -t simulator // for simulation

Same as Android. Also for more details regarding building for ios you can follow this doc Expo IOS Build Doc. This has a step by step instructions to build your app.

Or you can directly build ios and android app from xcode and android studio directly which is same as you do for standalone app.

Once done, if you want to push to the Apple AppStore, use:

expo upload:ios
