About this app

It's never been easier to get your diabetes under control. We developed diafyt Guide for daily use, optimized for simplicity and speed. That's why we've automated as much as possible and it only takes seconds to manage your diabetes. Even the insulin dose can be calculated. You can test the Pro version for 3 months. Integrated with FreeStyle Libre (c) CGM sensor.

1. Summary

Individuals with an absolute insulin deficiency require insulin replacement therapy which is given through injections or an insulin pump. The main goal of a diabetes management system is, as far as possible, to restore glucose metabolism to a normal state.

diafyt Guide is a diabetes management decision support system for insulin dependent patients on an ICT (intensified conventional insulin therapy). It helps patients who have difficulties finding the correct insulin dose. It consists of 2 software components, a smartphone app and a cloud application. To support patients in their daily diabetes management procedure diafyt Guide can calculate a directing value that correlates with the individual patient's insulin demand. Thus diafyt Guide can assist in achieving effective bolus dosing.

Patients will use a smartphone app connected to a cloud service for calculation and optimization. The system adapts to the individual patient with machine learning.

Typical use-case situation: calculate insulin dose prior to meal

The patient

starts the app
reads the glucose sensor data
estimates the amount of carbohydrates in the meal and records the value in the app
runs the insulin demand calculation and receives a directing value
makes a qualified decision about the dosage amount taking the directing value into consideration and records the chosen dosage amount
injects the chosen amount of insulin (bolus)

2. Medical Purpose and Intended Use

a) Medical Purpose
Diabetic patients need to calculate insulin dosages multiple times a day. diafyt Guide assists patients in their individual bolus calculation.

The principle of insulin dosage calculation is based on an algorithm that calculates a number that is correlating with the patient's individual insulin demand based on

blood glucose levels
insulin injections
types of insulin used
food intakes (carbohydrates)
time of day
parameter tuning functionality
further body related parameters e.g. weight, age, other chronic illnesses

b) Other Normal / Intended Use
In addition the app can be used for glucose monitoring and diabetes management. Related records can be stored and transmitted.

4. Characterization of Users
Users are patients who:

a) can operate apps on a recent smartphone
b) use a glucose monitoring sensor
c) actively manage their diabetes e.g. record data, count carbohydrates

5. Characterization of Patients

a) diagnosed with Diabetes mellitus type 1
b) on an ICT (intensified insulin therapy)
c) excluding patients with active tumor diseases, cortisone therapy, untreated thyroid dysfunction (hyperthyroidism), other pancreatic problems
d) excluding pregnant women
f) excluding children under age 14
