Instant Pulse measures your heart rate in just 8 seconds using the built-in wide-angle camera of your iPhone or iPad — no extra equipment needed. Simply place your finger calmly over the camera, stay still, and the app will measure your heart rate and save the result automatically. If you are using an iPad without a camera flash, take your measurements in a well-lit environment, such as under direct sunlight or near a light source. FEATURES • Measure your heart rate in just 8 seconds using only your finger and the camera. • Apple Watch app with watch complications to see your latest reading at a glance. • Reads and writes your heart rate data to Apple Health, including background sync. • View your latest heart rate reading from Apple Health directly on your Watch complication or Home and Lock Screen Widgets — without opening the app. • Schedule daily reminders to measure your pulse regularly. • Home Screen and Lock Screen Widgets. DISCLAIMER Instant Pulse measures your heart rate accurately but is not a certified medical device and should not be used for medical diagnosis or treatment. Normal resting heart rate for adults ranges from 60 to 100 beats per minute. Consult your doctor if your resting heart rate is consistently above 100 beats per minute (tachycardia), or if you are not a trained athlete and your resting heart rate is consistently below 60 beats per minute (bradycardia) — especially if accompanied by symptoms such as fainting, dizziness, or shortness of breath.

Verdict
The clearest difference is update cadence: i at fortnightly against Instant Pulse's every 4 months. Instant Pulse's advantage is device support (5 vs 2). On price, ads, in-app purchases and iOS requirement there is nothing between them.
