How to Build a Crypto Portfolio Tracker App?

Estimated read time: 4 minutes

A crypto portfolio tracker app development is a custom-build software development project. There are ways in which you can expedite the project. You can use ’Application Programming Interfaces‘ (APIs) to get crypto market data feeds in your app. I recommend this approach.

You will need to design and develop the mobile front-end, however, I recommend using a ’Mobile Backend as a Service‘ (MBaaS) provider for the backend. This saves time. More on this later. You need to assemble a capable team, and thoroughly test your app.

The right focus on project management is important for this project. We have guides such as “Top 7 project management methodologies in 2018” to help you with the project management best practices.

APIs for core crypto portfolio tracking app functions

Using APIs eliminates the need to ’reinvent the wheel‘, and the good news is that there are API options to access crypto market data in your app. Let‘s review the following API options:

CryptoCompare API

CryptoCompare, the app provider also offers APIs for cryptocurrency data. With their API, you can integrate the following data elements in your app:

  • The coverage for a wide range of cryptocurrencies;
  • A large set of trading pairs;
  • Trading data across a wide range of crypto exchanges.

The data includes the following varieties:

  • Price;
  • Historical data in different timescale ranges;
  • Volume data for top exchanges;
  • Streaming data for different combinations;
  • Crypto news articles.

This is a secure API, and you can access it here. You can check their pricing plans here, however, you need to contact them for more details.

Blox API

Blox, the financial management platform for cryptocurrencies offers an API. This API can be used to integrate with multiple blockchains and exchanges. Your app can fetch data from exchanges using this API.

The Blox API covers many prominent exchanges like GDAX. You can offer a dashboard in your app using this API, where you can manage difference exchange and wallet integrations. The API also allows one to review his or her past transactions.

Your team can access their tutorials here. You need to contact Blox for more information about their API.

Nomics API

Nomics, the crypto market tracking platform provides their API for cryptocurrency market data. Your mobile app can access price, market data, and information from crypto exchanges. They cover many cryptocurrencies. They also cover prominent crypto exchanges like Binance, Gemini, Coinbase, GDAX, and Poloniex.

You can get the following kinds of data with the Nomics API:

  • Trades and orders on more than 10 prominent crypto exchanges;
  • Historical aggregate crypto market cap;
  • Price, market cap, and supply.

This is not an exhaustive list. The data is near real-time. The company offers extensive API documentation, and you can access it here. Review their pricing plans here.

CryptFolio API

CryptFolio, the cryptocurrency accounting, and portfolio management platform also offer their API. With the CryptFolio API you can incorporate the following features in your app:

  • Users can synchronize their trades from different wallets and exchanges.
  • The app users can manage their tax liability arising from crypto trading.
  • Crypto market performance charts can be included in the app.
  • Users can set up alerts in the app.

The CryptFolio API covers key crypto exchanges like Bittrex, Bitfinex, GDAX, Binance, and Kraken. It also covers well-known crypto wallets like Ledger. New cryptocurrencies are automatically picked up; therefore, your app can automatically access their data. Access their API documentation here, and click here for their pricing details.

Coin Stats API

Coin Stats, the popular cryptocurrency portfolio tracker app also provides its‘ API. With this API, you can extract coin prices and show them in your app. It‘s possible to incorporate a historical global average price chart. You can get data from the crypto exchanges they support.

Your app can also display market prices across all exchanges. The API enables getting tickers prices for an exchange and a coin. Fiat currency rates, crypto-related news are other features you can incorporate with their API. Review their extensive API documentation here and contact them for their pricing plans.

The team to create a cryptocurrency portfolio tracker

You need to onboard a skilled development team with the following skills:

  • Business analysis;
  • UI/UX design;
  • iOS development;
  • Android development;

It‘s important that you identify a competent project manager (PM) who is familiar with the Agile methodology. We have a guide “How to build an Agile development team” to help with Agile development.

UI/UX design and development

The UI/UX is key, therefore, you need to focus on the following aspects:

Managing the mobile backend

While our guides can help with the UI/UX design and APIs are there to incorporate core functions, you will need more aides to expedite the development. Mobile backend development and management take time and ongoing effort.

Mobile backend involves many aspects, e.g., cloud infrastructure, handling persistent storage, provisioning a database, user authentication, user management, push notification, and security. MBaaS providers handle all these, therefore, subscribing with a reputed MBaaS provider can save significant time. I recommend SashiDo. I have earlier compared several MBaaS providers in “How to choose the best mobile backend as a service (MBaaS)?”, which you can consult.

Use effective tools for crypto portfolio tracker app development

A mobile app requires frequent enhancements. The release cycle has a short duration. Such development requires automation of testing, build management, and code deployment. You need to find a good combination of DevOps tools. I recommend you use Jenkins and Selenium. You can read “Top 10 DevOps tools you must know in 2018” for more recommendations.

You also need a good project management tool. Trello is a well-known PM tool. I have evaluated other tools in “The 10 best Agile project management tools in 2018”, which you can review for more options.

’Scrum‘ technique to create a cryptocurrency portfolio tracker

This is an Agile project, therefore, I recommend the ’Scrum‘ technique, which is suitable for iterative development. The PM is the ’Scrum master‘, whereas a ’Product owner‘ (PO) provides the requirements in a ’Product backlog‘ document.

The ’Scrum team‘ is a small and cross-functional team where developers and testers work together. The team estimates the requirements which are prioritized. The ’Sprint‘, i.e., iterations are planned with these inputs, in a ’Sprint planning meeting‘.

The team conducts a status meeting called the ’Daily stand-up meeting‘. When the features are ready, the team holds a ’Sprint review meeting‘ to demonstrate the features. The project stakeholders approve the sprint in this meeting, however, the team also conducts a lessons-learned meeting later. That‘s called the ’Sprint retrospective meeting‘. Read our guide “How to build a Scrum development team” to know more.
