If I want to know when a particular Bitcoin address sends or receives a payment, is there an Android app that will notify me via an alarm? Preferably one that polls the blockchain at least every 30 seconds to check for a transaction.
I know Blockchain.info offers this...but Blockchain.info has been having major issues recently..I don't feel safe keeping coins with them.
Any recommendations?
Thanks!!
I don't think such an app exists.
If you don't feel safe, then make some backups of your private key. Also make a strong password on you wallet, use cappitals, numbers.
