One app for blood sugar, insulin, GLP-1 and tablets
Applidia brings together what usually ends up in several notebooks.
Blood sugar
Each reading is saved with its moment: night, fasting, before or after a meal. Its colour shows whether it sits within the targets you entered. In mmol/L or mg/dL.
Insulin
Rapid, basal, mixed or bolus. The dose shown is the one you entered from your doctor's prescription. Applidia never calculates a dose.
Weekly GLP-1
For a once-a-week treatment such as semaglutide or tirzepatide, Applidia reminds you on injection day and keeps the history.
Tablets
Your medicines are sorted like a pill box: morning, noon, evening and night. One tap records that you took them.
PDF reports
Blood sugar, injections, both together, or medicines: one A4 report per category, for up to 31 days.
Private and Swiss
The app works offline and encrypts your data on your phone. Sync is hosted in Switzerland. An email address is all the account needs.

Your questions about Applidia
What the app does, what it does not do, and how your data is protected.
What is Applidia?
Applidia is a free app to log blood sugar, insulin, weekly GLP-1 injections and tablets, then create PDF reports for your doctor. It is made by Applidia Sàrl, based in Vucherens in the canton of Vaud, Switzerland.
Is Applidia really free?
Yes. Every feature is free, with no ads and no subscription. Voluntary donations are welcome but never required.
Does Applidia calculate my insulin dose?
No. Applidia is not a medical device and never calculates or recommends a dose. You first enter the treatment your doctor prescribed, for example a table by blood sugar range or by time of day. The app then shows what you entered, reminds you and keeps the log. Five correction tables (S1 to S5) are built in: choose one only if your doctor prescribed exactly that table. Any change to your treatment is decided with your care team.
Which treatments can I track?
Rapid, basal and mixed insulin, bolus tables, weekly GLP-1 injections with a reminder on injection day, and tablets grouped by morning, noon, evening and night.
Is my health data safe?
Your data is encrypted on your phone. Sync runs on servers in Switzerland (Infomaniak). The account only needs an email address: you do not have to give your name or postal address. Your data is never sold.
How do I share a report with my doctor?
In Reports, choose last week or this week, last month or this month, or your own dates (up to 31 days). Then pick the type: blood sugar, charts, insulin, blood sugar and insulin, or medicines. You can view the A4 PDF, print it or send it.
Does it work without internet?
Yes. Everything works offline. Your entries sync as soon as your phone is back online.
Which phones and languages?
Applidia runs on iPhone and Android, in English, French, German, Italian, Spanish and Portuguese (Brazil and Portugal). Blood sugar can be shown in mmol/L or mg/dL.
How do I get started?
Install the app, create your account with an email address and enter your treatment. 25 short video tutorials show each step, in the app and on YouTube.
