Blockchain Watcher

Blockchain Watcher (BW) is a simple application for watching the values of various blockchain assets! It was born out of a desire for me to be able to watch the values of specific addresses in a mobile, aggregated, multi-crypto way. It uses the awesome Ionic Framework which allows the app to support running on Desktop, Android, and iOS devices – that pretty much covers every consumer electronic device.

Core Features

Support for multiple types of cryptocurrencies

Bitcoin, Ethereum, Litecoin and more! BW will support many different cryptocurrencies allowing you to monitor the value of as many addresses as you desire.

Secure, uses public addresses only

By never exposing your private key(s), you don’t have to worry about security with the app. For cryptocurrencies that work in the same way as Bitcoin, you can simply provide your public address that is already freely visible on the blockchain, and monitor your addresses values.

Notifications and alerts

Be notified when a transaction posts to one of your addresses. This is a great way to keep track of deposits and debits that occur against your addresses.

Runs on Desktop, Android, and iOS

Thanks to the Ionic Framework, BW runs on many different platforms/operating systems. Some features may only be available on certain platforms, but the core functionality of watching addresses on various cryptocurrency blockchains will be available on all.

A lot of progress has been made! Checkout the updated screenshots above. In summary, I’ve implemented a lot of the basic functionality and software design for actually interacting with the block explorer APIs. I’ve added support for Bitcoin and Ethereum so far. Litecoin is next, and then I’ll begin to think about other cryptos that are a bit different like Monero. I’ve also added QR code scanning to the app, along with the ability to see the list of addresses in a given bin and the start of management functions over those addresses. A feedback screen is now available which allows users to provide their feedback to me, along with the most recent log messages from the app, useful for when I need to debug something.
