Availability depends on your device, permissions, connection, and recorded history. YOUR MEDIA, WITH HEART-RATE CONTEXT - Add a BPM overlay to workout photos and videos - Import existing media without changing your camera routine - Match photo times with nearby recorded readings when available - Save the finished media or open your favorite sharing app - Revisit captured moments alongside their BPM KEEP A RACE OR ADVENTURE MOMENT Bring available heart-rate data into a finish-line photo, a training clip, or an adventure memory. A matching reading may not exist for every photo or video. Video BPM may be estimated from nearby recorded samples. MORE CONTROL WITH PULSEID PRO Free includes videos up to 60 seconds, the full watermark style, and custom positioning. Pro adds no app-imposed video length limit, minimal watermarks, and video exports up to 4K. Device and storage limits apply. 4K requires a supported source and high-resolution output enabled. Pro is an in-app purchase. PRIVATE BY DESIGN Heart-rate data, photos, and videos stay on your device. Photo and video watermarking runs locally. Limited operational telemetry helps diagnose reliability and performance, but does not include heart-rate values, health records, photos, videos, chat content, or advertising identifiers. Authentication telemetry may include account identifiers, email addresses, and sign-in methods to diagnose signup and sign-in issues. AI chat uses on-device processing by default. On supported devices, you can separately allow Apple's Private Cloud Compute for newly typed messages. PulseID does not automatically include your health records, photos, profile, or chat history in these requests. You can withdraw this permission in AI settings. PulseID requires secure sign-in for app access and subscription management. Account data is kept separate from heart-rate data and media. IMPORTANT PulseID does not measure heart rate through the iPhone camera. It receives heart-rate data from Apple Watch, Apple Health, or a compatible Bluetooth monitor. PulseID is not a medical device and does not provide medical advice or diagnosis.

Verdict
The clearest difference is in-app purchases: Cardio Rounds at none against PulseID's 3. PulseID's advantage is update cadence (every 2 days vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
