Mobile App to track SPO performance

[GENERAL] Name and surname of main applicant

[GENERAL] Are you delivering this project as an individual or as an entity (whether formally incorporated or not)

[GENERAL] Please specify how many months you expect your project to last (from 2-12 months)

[GENERAL] Please indicate if your proposal has been auto-translated into English from another language.

[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

We want to develop the app to be useful for SPOs and bring all useful metrics into mobile app together with useful push notifications

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

I will use Prometheus as a backed as time series product to get all the data.

It make sense a lot because it is already compatible with Cardano Nodes and it is open source

[GENERAL] Will your project’s output/s be fully open source?

[GENERAL] Please provide here more information on the open source status of your project outputs

Mobile Application code will be published as open source here https://github.com/bkvpool/watchtower

[SOLUTION] Please describe your proposed solution.

I am proposing to develop a mobile app to track the state and performance of the Cardano Stake Pool and its nodes.

The app will not require any backend, my idea is to use available solution based on Prometheus which is gathering all the relevant information and use Prometheus API to show the data on the mobile application frontend. It will simplify solution and decrease its development time and costs.

The main target of the application are the SPOs but not only. This app can be used by usual delegators who delegate their wallets to particular SPO to track its state and performance (of course, SPO should have prometheus access publicly available in this case)

[IMPACT] Please define the positive impact your project will have on the wider Cardano community.

The impact of the app is more stable Cardano network as SPOs can have more control and better awareness about their nodes performance and issues.

Delegators will have more transparency and details on the Stake Pools where they have delegated their assets

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

I am solution architect and have long experience (around 20 years) working with different technologies and platforms, I have enough knowledge and resources to develop and maintain this kind of application.

I'm going to use this application myself for my own staking pool [BKV],I am very motivated to deliver as this app will make also my experience as SPO easier.

I'm creating this solution together with the professional Mobile Flutter Developer (a4ekw)

[Project Milestones] What are the key milestones you need to achieve in order to complete your project successfully?

The mobile application will be published on Google Play and Appstore and will be available for download for Alpha and Beta Users

It will have basic functionality

• watch some node and stake pool metrics
• set any prometheus endpoint
• auto update

Second version of the mobile application will be published on Google Play and Appstore and will be available for download for everybody

It will have extended functionality

• possibility to select and configure metrics
• possibility to track some stake pools
• possibility to filter prometheus labels

The mobile application will be published on Google Play and Appstore and will be available for download for everybody and will be well documented so any SPO can setup it for its own need.

Basic information will be detected and shown automatically.

[RESOURCES] Who is in the project team and what are their roles?

I will develop the application on my own, designing the solution architecture and developing the app itself.

[BUDGET & COSTS] Please provide a cost breakdown of the proposed work and resources.

• Designing the app architecture: 2000 ada
• Developing the navigation and main screens: 3000 ada
• Developing the module to read and deliver information from Prometheus API: 5000 ada
• Developing the widget to show text and numerical information: 3000 ada
• Developing the widget to show charts and graphics 7000 ada
• Setup and configure automated build of the mobile app using Bitrise: 1000 ada
• Test the application: 2000 ada
• Deploy the application to Google Play and Appstore 3000 ada
• Create the documentation for SPO and users: 1000 ada

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

Me and my colleague already developed even much more complex solutions and have proper experience to justify the estimation. Anyway, as we are working as a small team, it is easier for us to mitigate the risks of the development costs.

[IMPORTANT NOTE] The Applicant agrees to Fund Rules and also that data in the submission form and other data provided by the project team during the course of the project will be publicly available.
