What's My Heart Rate allows you to measure your heart rate by just looking at your screen. It's easy and convenient, without the need to press your finger on your camera lens. Your heartbeat causes micro color changes on your face. What's My Heart Rate uses the front camera and a software algorithm to detect these micro changes, with beat-to-beat accuracy. The algorithm is based on the non-contact photoplethysmography concept.
FreeDiams is a program for making prescriptions of pharmaceutical drugs and testing their interactions. It is the result of building the FreeMedForms prescriber plugins into a standalone application.

It can be linked to any application by way of its command line parameters. FreeDiams can use several drug databases, including the FDA_USA drug database, the French AFSSAPS drug database, the Canadian drug databases, and the South African drug database (SAEPI).

pdr (personal data recorder) and pdx (personal data expert) are applications that collect and evaluate mostly numeric personal data. The intended use case is for logging individual medical data (blood sugar, blood pressure, body temperature, weight, heart rate, and medications), but they can also be used for technical, sports, fitness, weather, environmental, or financial data. They work on a continuous flow of numbers in time that you want to monitor. Every data item can also be commented by text. pdr can use Twitter and email accounts for data input, which makes mobile phones usable for data input. It is one of the few free applications for diabetics.
iRelief is an app that provides a breath control training for the user to practice controlled training techniques, while providing bio-feedback on the user's training data. Using photoplethysmographic techniques and the iPhone's camera, iRelief is able to measure the heart rate and calculate Heart Rate Variability (HRV) just by placing the user's fingertip on the camera lens. The HRV is a measure taken by the beat-to-beat interval of the user's heartbeat, which based on existing research, increases as we inhale and decreases as we exhale.
Foods and Moods is an application that tracks what you eat and how you feel. It is aimed primarily towards people trying to track which foods may trigger their digestive problems. It does this by keeping two logs: a log of the foods you eat and a log of your moods. This provides you with a searchable history using keywords or "tags", so you may see for yourself if there is any relationship between the two. It doesn't attempt to do any medical or nutritional analysis.
