A diabetes app, designed by a patient.
Applidia is a diabetes logbook for iPhone and Android, made in Switzerland.
Wisdom in the service of health.
2017
A Swiss electrician with type 2 diabetes, now retired, decided to devote his time to a project he had carried for years. For five years he thought through, sketched and refined every screen, with the care of someone who lives with diabetes every day.
2024
Unable to find anyone to build his idea, he teamed up with a young engineer who had just graduated from EPFL in computer science. Together they brought the project to life: youth in the service of wisdom, code in the service of lived experience.
About 800 million people live with diabetes worldwide. Applidia was made for them. It is built with rigour and supported by the generosity of its users.
Free, with your data in Switzerland
Applidia is free, with no ads and no subscription, and your data is never sold.

An email address is all your account needs. Your data is encrypted on your phone and on Infomaniak's servers in Switzerland. You can delete it at any time. Privacy policy
Applidia never calculates a dose.
It is not a medical device. It logs, reminds and prepares your reports. Your treatment is decided by your doctor.
For the bolus feature, five ready-made correction tables (S1 to S5) save you typing. Only choose one if your doctor prescribed exactly that table; otherwise, enter your own. Read the medical disclaimer
How we write our guides
Every guide cites its sources and shows when it was published and last updated. Our new guides stay offline, in review, until a health professional has read them. Their name will then appear on the page. Medicines are named by their active ingredient, never by brand.
