Questions & Answers

As answered by people managing Interval Timer (PFA) and BlindClock.app.

What makes your product unique?

BlindClock.app's answer:

You don't need to keep the app open to see the clock. The current level shows on the Lock Screen and in the Dynamic Island, an iPad in landscape works as a table display, and with Pro the clock can go on a TV or projector while the phone works as the remote. It also runs offline and needs no account.

Which are the primary technologies used for building your product?

BlindClock.app's answer:

Swift and SwiftUI. SwiftData with CloudKit for iCloud sync, ActivityKit and WidgetKit for Live Activities and the Dynamic Island, StoreKit 2 for the one-time Pro purchase, and TelemetryDeck for usage analytics.

Why should a person choose your product over its competitors?

BlindClock.app's answer:

It handles the whole tournament in one app: it builds the blind structure, runs the clock, and works out payouts, and Pro adds ICM chops and chip counting for the end of the night. The free version runs complete tournaments with no ads, and Pro is a one-time purchase, not a subscription. The app is available in 12 languages and syncs tournaments between iPhone and iPad through iCloud.

How would you describe the primary audience of your product?

BlindClock.app's answer:

People who host poker tournaments at home, and small clubs that run their own events. Many hosts also play, so the app is built to keep running on its own once the game starts.

What's the story behind your product?

BlindClock.app's answer:

I'm Shi-Kai Pan, an independent developer in Taiwan. I built BlindClock because when I played poker with a group of friends, we could only raise the blinds with the iPhone's countdown timer, and there was no good tool for keeping track of a time bank. It launched in June 2026, and some updates since then started as emails from hosts, such as showing the upcoming level in the Lock Screen Live Activity.
