Ringable shows you when friends are free to talk. Toggle your status; friends you've connected with see it instantly.
Tap + and enter their 6-character ID. They'll get a request; once they accept, you can see each other's availability.
Either they're busy, they haven't opened the app in over 30 minutes (statuses auto-expire so they're never stale), or they've hidden their availability from you.
Tap the eye icon on their row. They'll simply see you as Busy until you unhide.
Ringable uses anonymous, device-based accounts with no passwords. A reinstall creates a fresh ID — share the new one with your friends.
Settings → Delete account. Removal is immediate and permanent. Details in the privacy policy.
