FREQUENTLY ASKED QUESTIONS

Everything you need to know about RUNSTR

What is the difference between saving a run and posting a run?
Saving a run will add it to your Nostr workout record (kind 1301), creating a permanent record of your fitness activity. Posting a run will create a social media post on Nostr with a short summary of your run, sharing your achievement with your followers.
How does this app use Bitcoin?
We leverage the Lightning Network and Nostr Wallet Connect (NWC) for instant Bitcoin payments. Teams can receive payments via NWC connection strings, and users can pay event entry fees or zap teammates using any Lightning-enabled wallet including Cash App, Strike, or Alby.
Is this app private?
Yes! We have no user accounts and don't hold your money or data. The workout data in this app is stored locally on your device until it is broadcasted as a public workout to earn sats. You maintain complete control over your data and funds.
