# Work To Do

### Ongoing
1. Time-series database queries for off-chain Telemetry notifications (best/finalized block height, uptime, up/download bandwidth, peer count, transaction queue length).
4. More integration tests and Prometheus integration for the backend.
2. Notification content templates for different channels (push notification, SMS, email - working with the design team for these) and text-to-speech content for GSM calls .
3. Twilio integration for SMS and GSM notifications - near completion.
4. Backend data access frameworks for iOS (Swift) and [Android (Kotlin)](https://github.com/helikon-labs/subvt-data-android).

### Milestone 4
1. Complete iOS and Android application development.
2. Work with the design team for emergent changes.
3. Begin alpha testing.

### Milestone 5
1. Beta testing & QA.

## Time and Budget

We're planning to begin open beta testing in early May, and release mid-June.

Budget for the last 2 milestones is **18,680.00 EUR** as stated in the initial spending [proposal](https://docs.google.com/document/d/1mCD1lRoEwbV3Xp5N-HzEKA0KROCmNkMFInLGd4nAz-k/edit?usp=sharing), equivalent to 21,417.55 USD as of 13.01.2022.

Thank you very much for your support and attention, and please share with us your ideas, questions and comments. We really hope we are on to something very useful, and are looking forward to sharing the applications with the community.
