What’s New

Version 1.5.1

Hello :) Thank you for your feedback and patience! We identified a bug with the change addresses happening with some XPUB wallets (not all though). Of course, coins still existed, but some addresses were visible while others were not. It is now fixed, and XPUB wallets generate both the main addresses derivation and the change addresses derivation in parallel.
Happy ⓢats ⓢtacking!

The Real Lando ,

Love it but...

I love the simplicity and ease of use of this app, and it did work really well for tracking multiple addresses for a few days, but now I just get a red dot next to the addresses I’m tracking and they all inexplicably show a zero balance. Looking forward to updates and additional features like notifications!

Developer Response ,

Hello. Thanks for the review. We had a few issues with the explorer API we used. So we added a setting allowing users to choose between explorers (for the moment you can select Mempool or Blockstream, and we will add more options soon). Sorry for the inconvenience!
