Gratis iOS application to track how much WiFi data I currently use

Question

I'm looking a gratis iOS application that can track how much WiFi data I currently use.

I am aware of the the following applications, but they are not gratis:

• https://apps.apple.com/gb/app/system-status-pro-hw-monitor/id401457165
• https://apps.apple.com/us/app/dataman-data-usage-widget/id592962356

On Android I use Network Speed - Internet Speed Meter - Indicator:

Usage provides something like that in its free version. If you want to customize over what period to count the data consumption (other than per day / per calendar month) you will have to pay the €4.99 for the full version however.
