Data display problems

I bought late September 2026 a Lüft radon/indoor air-quality monitor (Luft_C062).

I am using the lüft app on both an iPhone 13 Pro and an iPad Pro 11-inch.

I have two problems:

1. Trend chart:
The trend chart records the data correctly, and when I touch the graph I can see the exact time and measurement. However, the horizontal axis does not display any dates or times. Is there a setting that enables dates/times to be displayed on the horizontal axis?

2. Dashboard:
On my iPad Pro, the dashboard displays all six measurements: Radon, tVOC, eCO₂, Temperature, Humidity, and Air Pressure.

However, on my iPhone 13 Pro, the dashboard displays only

Updates broke the app

Don’t update to iOS 26 version. The historical graph is broken and nothing is better

Stopped working

App just locks up now when I open it. No chance to reset or reconnect or anything.

App crushes continuously

Great device, the App is a complete disaster. Can’t sign up from iPhone. I created a profile with another device.. it randomly disconnects. Now completely stopped working for an undisclosed “error”

Works but could use improvement.

It complains and fails to work if you don’t allow it to use location services and it requires a restart after you do give access in order for it to connect. It also requires you create an account. It does not allow upgrading the firmware using a Bluetooth connection, only works via 2.4 ghz WiFi. It requires hitting a not so obvious sync icon in order to get the current meter readings. It sets a lot of device settings on first run after creating an account but I could find any way to change these later. The temperature reading is sometimes inaccurate and seems to be off due to the Lüft device heat. It’s hard to find and difficult to set the threshold settings because they’re unusual, not simple, and non-intuitive. I had to enter my WiFi settings multiple times because it doesn’t give any error message when it doesn’t work, it just doesn’t work. The “trick” to get WiFi to work is to restart the app after giving all required location and Bluetooth permissions before entering the WiFi settings. I felt it unnecessarily intrusive on my privacy.
