Pink Vein

How it works

1. Open Pink Vein. Tap the + to start a new reading.
2. Type the three numbers from your cuff: systolic, diastolic, pulse.
3. Add a memo if context matters (after exercise, before coffee, etc.). Optional.
4. Tap Save reading. The reading is filed under today's date and time.
5. Open the trend chart to see the line of readings across the week, month, and year.

What stays on your device

• No accounts, no email, no signup.
• No analytics, no third-party SDKs.
• No Apple Health integration. Readings are kept inside Pink Vein only. If you also want them in Health, type them there separately.
• Readings are stored on-device with SwiftData. Nothing leaves your phone.
• The only network calls Pink Vein makes are to Apple's StoreKit when you choose to subscribe or buy Lifetime.

What you need

• An iPhone running iOS 18 or later.
• A blood pressure cuff of your own. Pink Vein does not measure, it logs what you read off your cuff.
• That is the only requirement. No microphone, no camera, no Health data, no sensors.

Pricing

Pink Vein lets you log readings for free. The last 7 days stay visible. Pro unlocks full history, the trend chart, and the year artifact:

• Pro Monthly: $3/month, with a 14-day free intro on the first subscription.
• Pro Annual: $13/year.
• Pro Lifetime: $29 one-time.

All purchases are handled by Apple and managed under your Apple ID. Pro is Family-Shareable through Apple's standard Family Sharing.

Pink Vein is a log, not a medical device. The readings you type come from your own cuff. If a number worries you, talk to your doctor.
