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 is developed by medical doctors and is intended for use by these same professionals. It can be used to prescribe drugs and test drug interactions within a prescription. 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).
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.
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.
OpenHIM is a health information mediator that aims to enable easier interoperability between disparate health information systems. It was developed as the Rwandan reference implementation of a health information exchange for maternal health, and is intended for use in low resource settings.
Diet Monger Ass Kicker (DMAK) helps the user design diets according to the user's specifications. The EuGTK version of DMAK, unlike the wxEuphoria version, does not require a *.so file, which was a problem for some people. It uses USDA data, and does sorting and filtering and calculations, and has Google search features, and gives you virtually all knowledge known to man about 7500 foods and 140 nutrients. It uses *.req files, which you can create or edit, and which determine the nutrient requirements. It remembers your settings. It has file features and clipboard features. Documentation is thorough. You can upgrade the data every time the USDA updates their data.
