After several years, I finally found a #FreeSoftware workout timer for #Android which is comparable to my standalone timer I used for ages. Here the @fdroidorg link:
https://f-droid.org/packages/io.github.deweyreed.timer.other/

It is simple, fast to configure, and fixes one of the blockers I had with other apps before: I can listen to music, and get just brief audio notification about the next interval. Over the last months I could now travel without packing a separate timer and batteries.
