Is the free plan time-limited?
No. There is no expiry, no trial period and no card to enter. You can host every one of your evenings without paying; the trade-off is the Scorofun strip at the bottom of the display and the limit of two live games at a time.
What happens when my event pass expires?
Your account simply returns to the free plan. Nothing is deleted: your games, scores and history stay available. The strip comes back on the display and the two-game limit applies again.
What is the difference between Pro and Venues?
Functionally none: Venues does everything Pro does. The difference is legal and about use: Venues allows the display to be shown in a place open to the public, commercially. A bar, a games venue or a club charging admission belongs there.
Does an in-app purchase also unlock the website?
Yes. Entitlements are reconciled server-side and attached to your account whatever the source of the purchase: a pass bought in the iOS app applies when you host from a browser too.
Can I buy several event passes?
Yes, one per event if you like. That works out well for three or four evenings a year; beyond roughly one event a month, the Pro subscription is cheaper.
