The obvious smart-a** answer to your title question is: your ears.
As Brother Steve says "Although in general, people with perfect pitch do not take up the tin whistle!" - I'm pretty sure he was describing me in particular.

Heck, I like my original Conn ST11 Strobotuner, too. But I wouldn't recommend carrying that around. (Hint: 10 lbs).
They seem to run at about ~$25/pound, so it costs even more than lunchmeat, but it is quite pretty to look at!

I would caution that if you're not getting reproducible results on tuner X, then tuner Y or Z may not help. Consistency is up to you, and you need to find the right breath plateaus for each note, else tuning your whistle to a G or A or whatever won't give you the intonation you need.
Very good advice - thank you! I performed a somewhat controlled (and simplistic) experiment on the software by using various tones generated by my PC to make my decision. I had been getting swings of 50+ cents while practicing and suspected that even I'm not that bad...

I have an "entry level" Android that seems to get bogged down by the simplest of activities, so I suspect that the sampling is being distorted by the processor bogging down.

You might really want to play with the Flutini app, which gives you a real-time inventory of your pitches. Don't have time to search the link; maybe someone else can oblige ...
I'll find it - thank you again!
