Yep, that's what my research said, it's Samsung applications.
I did manage to find good replacement on the Play Store for chronometer and timer, and for Notes and synchornisation.
However, I am still struggling to port the one I had (and that are now backed up as Google Drive docs) into the new Note app I did take.

I did downlad as well the FM Radio apk that was missing from the ROM.
It seems to work well and even include RDS

Should try the NEATROM which is base on Stock Samsung ROM.

I have been using this ROM for sometime now. In Australia I also flash the xxlpx modem. Works very well, good battery life, everything works.

I have tried RR, CheckROM, Omega, CM9 etc, but if you want everything to work smoothly, stick to StockROM.
