Wave Focus

A beautiful and simple Pomodoro timer application.

Frontend

Mobile

We use React Native for iOS and Android.

Android

Follow this guide to build the release variant of the application.

After creating the keystore, run ./gradlew signingReport in the android directory to get the SHA-1 and SHA-256 fingerprints of the newly created keystore. Then, make sure to copy the fingerprints over to the Firebase project settings for the Android application.

iOS

Follow this guide to build and publish the application.

Backend

Wave Focus is built on Google Cloud Platform (GCP). It relies on:

• Firebase Authentication to provide user accounts and timer sync across multiple devices
• Firebase Firestore for its realtime document database
• Firebase Cloud Functions to schedule and trigger notifications
• Firebase Cloud Messaging for push notifications
• Google Cloud Tasks API
  • A queue wavefocus-notifications in us-central1 is used to queue notifications for deferred delivery

Notifications
