Great idea plus excellent implementation!
After the other app with similar function failed to measure my wifes heart rate, I found this app. Love the real-time feedback on the quality of sample collection, aka "Get the square red colored", also like the fact that it collects sample for 30 sec and calculates the average. Also, I found that with the real-time sample quality feedback, I dont need to take the iPhone out to the case to get a good reading, and it reads my wifes with no problem.
One suggestion for future update is to add feedback sound for every pulse it detects. Other than that, a solid 5-star for a free app.
