ComputeUnion VS BlindClock.app

ComputeUnion's answer

ComputeUnion was built out of personal frustration. Manually checking prices across a dozen AI platforms before every project was tedious and error-prone. The solution was to automate the entire process — building scrapers for every major provider and presenting the data in one unified interface. What started as a personal tool grew into a platform covering 70+ providers and 3,000+ models.

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.

ComputeUnion's answer

ComputeUnion is one of the few platforms that tracks both AI API pricing and GPU cloud rental rates in one place, with data updated hourly via automated scrapers — not manually maintained spreadsheets. It also covers CN relay stations for developers in China, a niche completely ignored by Western competitors. With 150+ model-vs-model comparison pages and price history charts, it goes beyond simple price lists into actionable decision tools.

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.

ComputeUnion's answer

Most price comparison sites rely on manually updated data that goes stale within days. ComputeUnion runs automated scrapers across 70+ platforms every hour, so the prices you see are the prices you'll actually pay. It also covers more provider types in one place — official APIs, third-party relays, and GPU rentals — eliminating the need to check multiple sources before making a decision.

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.

ComputeUnion's answer

AI developers and ML engineers who use LLM APIs in production and want to minimize costs. Also serves researchers comparing GPU cloud providers for training workloads, and developers in China looking for cost-effective API relay stations.

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.

ComputeUnion's answer

Next.js 14, TypeScript, Tailwind CSS, PostgreSQL, Python, Vercel

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.
