Add the wallet address you want to watch. Cointer checks the blockchain for you. When a watched address gets a deposit, you get a notification. No accounts, no passwords. Just a single personal key that ties everything together.
You can pick how you want to be notified: push alerts, ntfy, Discord, Slack, or email.
Cointer is free, with no ads or paid tier. Donations pay for the servers, and the more that comes in, the more chains we can support. Addresses and QR codes are at cointer.app/donate.
