I released my first android app Crypto Contacts a few months back on the Playstore. I'm a desktop wallet user and I needed an easy and clean way to keep track of my addresses while away from my computer so I made Crypto Contacts. It's free in the Android Playstore so I'd really appreciate it if you could check it out and give me some feedback.
What problem does it solve?
- Allows you to save your public key crypto addresses locally on your android device so you have access to all your addresses while on the go.
- Prettier interface for organizing your public key crypto addresses (I used excel/google sheets/plain text before)
- Prevents accidental partial copies (I was always afraid of not copying the whole address or messing it up somehow)
- Makes saving and sharing public key crypto addresses easier (added QR functionality, quick copy, and share to contacts options)
- Ability to take notes on each address
But what about reusing addresses?
- Generally, you shouldn't be reusing addresses.
- Simply generate as many addresses as you need while you're at home using your favorite wallet, save them to the app and then delete or make note of them on the app once they've been used, that way they're only used once.
Extras I wanted in my app
- Crypto Conversion Calculator
- Current crypto to fiat or btc, eth prices
- Supporting 1500+ cryptos and all fiat currencies
(all rates/conversions are handled using the cryptocompare api)
THIS IS NOT FOR SAVING YOUR PRIVATE KEYS
This app is just for your receive addresses.

If you have any feature suggestions, feedback or questions, I'd love to hear them as this is my first app and I'm looking to improve.
