Peak Flow Meter V2

This mobile app is designed to automatically record and store the peak flow readings (Peak Expiratory Flow Rate) from the Cipla peak flow meter (also known as Breath-o-Meter):

This mobile app enables the automatic recording of the peak flow meter reading without the need for bluetooth or batteries. This mobile app is intended for use by community health workers or patients in low-resource areas, where more electronic peak flow meters are not available.

This mobile app requires the use of a printed sticker that should be applied to the peak flow meter. The sticker design can be requested directly from the MIT Mobile Technology Lab (www.mobiletechnologylab.org)

Using a computer vision tracking algorithm, the mobile app automatically records the reading and also provides visual feedback to the user.
