Measuring Turntable Platter Speed

I have an older Rega P2 that seems to warble (for lack of a better word) when playing. It's not that it's fast or slow, but I can hear slight, quick, pitch changes when playing a record. I put a new belt on, but no change.

Is there a method or relatively inexpensive instrument that I could use to monitor small fluctuations in platter speed?

Thanks in advance - Jim S.

KAB, the folks that cater to the Technics SL1200 crowd with parts and accessories sells a very nice strobe disc and lazer light. Amazing just how still my rebuilt Victor TT71 platter looks when using it. Anyway, disc and lazer is $109.00

The phone apps have plenty written about them, not super accurate but a good comparative tool. I use one as well, the RPM Speed and Wow app.
