App guide

How to use LifeSugar, step by step

Everything the app does, in the order you'll use it: from opening it for the first time to sharing your diary with your doctor or nurse.

Each chapter shows the app in action, step by step. It plays on its own, and you can pause it or jump to any step you like. The app is on Android.

Chapter 1 · Getting started

How to start using LifeSugar

You sign in with your Google account, confirm your phone and tell the app just enough for its numbers to be yours. It takes a few minutes.

1.Take the tour, or skip it

The first time you open the app, nine screens show you what it does. If you're in a hurry, tap Skip.

Step 1 of 8

Good to know · Getting started

If the text message still doesn't arrive after Resend, check that the number is right and that you have signal; if it still doesn't come, email us at info@lifesugarcare.com.
Your account can only be open on one phone at a time. If you sign in on another one, the app asks you and, if you carry on, the session on the first one is closed.
Your doctor's email is the only optional part of signing up. If you don't add it now, you can add it whenever you like in Settings → Personal data.
For now it can be downloaded in Spain, on Google Play. You need Android 12 or later with Google services: it doesn't work without them. It also works on an Android tablet with a camera, although it's designed for phones.
It's for people aged 14 and over. If your child is younger, the account and the phone are yours, and you log things for them.
The app doesn't work on rooted phones or phones with a modified system: this protects your health data.

Chapter 2 · Glucy: photo of your plate

How to count the carbs on a plate with a photo

Glucy looks at the photo of your plate and gives you its carbs in grams and in portions. There are two ways to do it, with the same Glucy and the same result: from the Food basket, the quickest, or from her chat. Choose one and see how it's done.

1.Open the basket

In the Food tab, tap Basket, at the bottom. That's where you put together everything you're going to eat.

Step 1 of 4

Chapter 3 · Food

How to search for a food or scan a package

In the Food tab you search for a food, scan its package or create it —by hand or from a photo, with Glucy—, and put it together in the basket to move it to your diary.

1.Search for a food

In the Food tab, type in Search for a food. Your favourites come up first, then Your foods and after that the database.

Step 1 of 8

Chapter 4 · Your diary

How to log your glucose, your insulin and your meals

The diary is the first tab: your day sorted into time bands, with your glucose, food, insulin and exercise all in the same place.

1.Your day, at a glance

At the top, your average glucose, your estimated HbA1c and today's insulin. Underneath, each entry in its time band: morning, midday, afternoon and night.

Step 1 of 6

Good to know · Your diary

The app's estimated HbA1c appears in the 3-month summary and needs blood glucose readings from 14 different days; until then it tells you how many are missing. The doctor's dashboard uses its own rule (30 readings over 14 days), so the two figures may not match. It's an estimate: the one that counts is the one from your blood test.
Exercise is logged in the entry, in the Exercise section: type, minutes and, if you like, calories. The app doesn't connect to watches or to Google Fit.
You log your blood glucose readings yourself: the app doesn't connect to sensors or to glucose meters.
The diary works offline and syncs when the connection comes back.
To correct an entry, tap the pencil next to its time: you can change it or delete it.
An entry is logged from today backwards: the app won't let you save it with a date that hasn't come yet.
The post-meal reminder appears after an entry with glucose and rapid insulin, and needs your rapid insulin's duration of action (Settings → Rapid insulin). The basal one needs your usual dose and time. If Android asks you to allow “Alarms & reminders”, accept it: without that permission the reminder may arrive a few minutes late.

Chapter 5 · Glucy: ask her

What you can ask Glucy, and what she won't tell you

Glucy is the app's assistant. As well as analysing photos, she answers questions about food and diabetes and estimates what you tell her you've eaten.

1.Ask her a question

Type or dictate with the microphone. She answers calmly and briefly: what a portion is, what's in a dish, how to read a label.

Step 1 of 4

Chapter 6 · Your doctor or nurse

How to share your diary with your doctor or nurse

Your doctor or nurse doesn't use the app: they log in to a web dashboard where they see your diary laid out. You give them access, with their email, and you can take it away whenever you like.

1.Open Settings → Personal data

It's the fourth tab. Under Profile and health, tap Personal data.

Step 1 of 4

Chapter 7 · Account and Prime

How to manage your subscription and your account

LifeSugar has a single plan, Prime, with a 14-day trial. Everything about your subscription and your account is in Settings.

1.Look at your subscription

At the top of Settings, the You're Prime card. Tap it to see your subscription.

Step 1 of 5

Good to know · Account and Prime

To start the trial, Google Play asks you for a payment method and lets you know before the first charge. If you cancel before the 14 days are up, you're not charged.
There's a single plan, Prime, monthly or yearly: no family plan and no discounts. Refunds are requested on Google Play.
Deleting your account doesn't cancel your Google Play subscription: cancel it first, in Manage on Google Play.
Changing phones? Sign in with the same Google account: your diary and your subscription come back on their own.
The app is available in Spanish, Catalan, English, Basque, French and Galician. Changing the language is available on Android 13 or later.
If Prime ends, your data stays saved: Settings stays open, the rest of the app is locked until you subscribe again and the reminders go quiet. Your doctor can still see your diary.
Changed your phone number? It can't be changed from the app: email us and we'll do it for you.
