## What is GlucoseWatch?

GlucoseWatch: Your Blood Sugar Values – Always on Your Wrist.

With GlucoseWatch, you have full control over your blood sugar values, directly and discreetly on your Apple Watch. This app, specially designed for Apple Watch, allows you to quickly and easily retrieve and visualize your glucose data from your Freestyle Libre Link Account.

Your Values at a Glance: See your current blood sugar values and their trend directly in the app. For a quick overview, you can even display your values as a Complication on your watch face. Please note that complications do not update data continuously. To get the most up-to-date values, simply tap the complication or open the app – the data will then update automatically.

Optional: Apple Health Integration. Want to see your glucose data in Apple Health too? GlucoseWatch offers you the optional ability to sync your blood sugar values with Apple Health, providing a comprehensive overview of your health data in one central place.

Security and Data Privacy Come First. We understand how important the protection of your health data is. GlucoseWatch processes all your blood sugar values and your access credentials for the Freestyle Libre Link Account exclusively locally and securely on your device within the iOS Keychain. No data is stored on external servers or shared with third parties.

Important Note: This app is solely for the visualization and monitoring of blood sugar values. The app is not a substitute for medical advice or treatment. Always consult a doctor or medical professional for health-related questions.

### 4/5 — Good Graph Graphics

*2026-08-12*

I like this application.
Complications are now updating.
Small complication font still needs increasing for us older people. 
I would also like the small complication gauge colour to change as per my level. ie green = in limit, orange = high and red = low.
The graph graphics are good.
I would like the developer to consider my suggestions.

**Developer response:** Thank you very much for your kind review and thoughtful suggestions! We’re happy to hear that you like GlucoseWatch. We’ll continue working on improving complication reliability where possible, and your feedback about increasing the small complication font is very helpful. Better readability is important to us, and we’ll consider this for a future update. Thanks again for helping us make the app better!

### 1/5 — 退款

*2026-07-30*

不是，你们这收了钱又用不了。能不能退钱啊，客服跟我联系了一半，一堆废话，也没解决

**Developer response:** 您好，不需要 Apple Watch 具备蜂窝网络功能。只要 Apple Watch 可以通过已配对的 iPhone 或 Wi-Fi 连接互联网，就可以使用 GlucoseWatch。

如果无法登录，请确认您使用的是已接受邀请的 LibreLinkUp / 瞬感通账号，而不是用于扫描传感器的主账号。建议先在官方 LibreLinkUp / 瞬感通应用中确认可以看到血糖数据，然后再用同一个账号登录 GlucoseWatch。

感谢您的反馈！

### 1/5 — 仍然无法登录…

*2026-06-30*

手机上的舜感通明确是可以登录，并看到血糖指标。但手表上用相同的账号登录，无法登录。并没有告知账号密码错误，而是跳出：“not logged in please log in to save your settings.”的信息，而且反复跳出。不管账号密码输入多少遍，输入的对错与否，都是这一个信息

### 1/5 — 无法登录

*2026-06-24*

一定要手表具有蜂窝联网功能吗？

### 2/5 — 可能无法登录

*2026-05-27*

我试过flwatch，瞬感通的账号和密码是正确的，可以连接，但在该程序上，无法连接。

**Developer response:** 您好，感谢您的反馈。GlucoseWatch 需要使用 LibreLinkUp / 关注者账号登录，而不是传感器使用者本人的 FreeStyle Libre / 瞬感通账号。

请先确认您已经在 LibreLinkUp 中作为关注者收到并接受了邀请，然后再使用这个关注者账号登录 GlucoseWatch。您可以在这里查看设置说明：

如果仍然无法连接，请通过 [glucosewatch@chadly.de](mailto:glucosewatch@chadly.de) 联系我，我很乐意帮助您进一步排查问题。谢谢！

### 5/5 — Game changer

*2025-11-08*

Beim Gravelbiken der Game changer für mich, da ich immer die Werte im Blick habe ohne das Handy rauszuholen

### 1/5 — Login

*2025-11-05*

I’m trying to login, it’s asking for a password,?  What password is it looking for???

**Developer response:** Hello,

Thank you for your review. We are very sorry for the confusion about the login. This is a common point of misunderstanding, and we appreciate the feedback.

The app is asking for your LibreLinkUp account credentials (email and password).

Important: This is not your main "Freestyle Libre" / "LibreView" account. It is the separate "follower" account that you must first create via the "Connected Apps" -> "LibreLinkUp" section in your main Freestyle Libre app.

As per the setup instructions (in the App Store description and on our website), you must first invite an email address from your main Libre app to create the LibreLinkUp connection.

You must then use those specific LibreLinkUp credentials to log into GlucoseWatch.

If you still have trouble, please contact us directly at glucosewatch@chadly.de , and we will be happy to walk you through the setup.

We are constantly working on the app to make it a 5-star app for you.

We hope this helps clarify the process
