rcx VS rcloneExplorer

RCX on android[0] gives a reasonable experience for pecking at files (Also handles media streaming reasonably well and supports the Crypt remote mentioned in the parent)

If you are using android there is RCX (https://github.com/x0b/rcx) as a frontend to rclone. Rclone can also be used in termux. Not sure about apple.

If you need an Android client, you have RCX https://github.com/x0b/rcx

I've read a little about https://github.com/x0b/rcx and my main question now basically is, if somebody who use or have used it already could confirm the more or less "hassle free" access/managing of files from the cloud within that application.

RCX (Rclone Crypt) or Rclone on Termux (it has a more updated version)

the only rclone client on Android I am aware of is RCX (available in PlayStore as well).

Rclone for Android: https://github.com/x0b/rcx

You mean this - https://github.com/x0b/rcx ? The fact, that latest version is released at Jul 15, 2021 and it have 110 unsolved issues, doesn't sound very reliable, and unfortunately it can’t access GDrive anymore.

Maybe an app like RCX (google play link) would work?

There is also rclone Explorer but it isn't maintained anymore. But I just found https://github.com/kaczmarkiewiczp/rcloneExplorer looks promising, but it's new to me. If you try it give me a shoutout if it's usable.
