## What is EasyFPU?

An iOS app - mainly for Type 1 Diabetes patients - to ease the calculation of sugars, regular carbs, fat-protein-units (FPUs) (aka extended carbs, e-carbs or fake carbs) and their matching absorption time.

Fat-protein-units are known to be the reason for late blood glucose rise. Many semi-automated insulin pumps allow you to enter these e-carbs, so that the pump can deliver more insulin.

Main features are:
- Maintain your own, personal dishes and easily compose meals containing as many dishes as you wish
- Search for products in OpenFoodFacts food database
- Scan barcode of products
- The app calculates your meal's total calories, sugars, carbs, extended carbs (e-carbs) from fat and protein (FPU - Fat Protein Units), and recommends the time your body will need to absorb these e-carbs (aka. absorption time)
- Store your sugars, carbs, e-carbs and/or calories in Apple Health (only on user request, no automated storage) for utilization by other apps
- Synchronize your food list across all your iOS devices via iCloud (optional)

## Key features

- Calculate sugars, carbs, and fat-protein-units (FPUs)
- Estimate e-carb absorption times
- Create and manage personal dishes
- Search OpenFoodFacts database
- Scan product barcodes
- Sync food lists via iCloud
- Store data in Apple Health

### 5/5 — Empfehlenswert

*2025-08-07, version 3.3.0*

Wir sind sehr zufrieden, berechne für meine Tochter und seit dem gibt es keine hohen Werte mehr die wir uns nicht erklären können!
Wir würden uns noch Kategorien wünschen, wo wir besser sortieren können :)

### 3/5 — Umsetzung verbesserungswürdig

*2021-09-23, version 2.1.0*

Die Idee ist sehr gut. Mit iOS 15 ist jedoch kein Export zu Health möglich. Der Button existiert nicht oder nicht mehr. Ich könnte darauf auch verzichten, wenn man sich das Diagramm auf anderem Wege anzeigen lassen könnte.

### 3/5 — Cannot scroll yo see full data.

*2021-07-11*

My son has Type1. It looks as if this app would be useful but I can only see what fits on 1 screen — cannot scroll to see sections below the screen (e.g. I can’t see the further details, or when in landscape mode I can’t see the full e-Carbs info. Please. Or text scrolling feature — possibly due to my older, smaller iPhone 6s? UPDATE: to answer your question, as identified above I have an iPhone 6s.

UPDATE:  thanks for the response.  Understood, and respectful of your time.  I’ll keep a lookout for updates as this app does seem to fill a gap in available functions for Type1 users.  Thanks again!

**Developer response:** What iPhone are you using?

Update on your answer (iPhone 6s): I’ll take a look at it, but it can take a couple of weeks, as I do all this in my spare time, which currently is very rare. Sorry about that.

### 5/5 — Amazing!!!

*2021-06-18*

This is such a wonderful app.  We are having a MUCH easier time bolusing.   Thank you!!

### 1/5 — Geht leider nicht

*2021-04-23, version 2.1.0*

Leider geht die App nicht bei mir. Egal was ich mache bekomme ich bei der Suche immer einen Netzwerkfehler. Schade
