Simple Metronome on Android is pretty good. It's got a visual click feature so the screen lights up a different colour on the first beat, which is really useful. Also it's free, no ads.
I tried foot tapping, but like others said, if your rhythm's off anyway, it won't do you any good. I got a free metronome app and put it on my phone. (I use this one: https://play.google.com/store/apps/details?id=org.ethanbrown.android.SimpleMetronome&hl=en_US )
It took me a bit of trial and error to discover that I feel comfortable at 80 bpm. (I'm super new with a mere 3 weeks of playing under my belt.) I had to put the metronome at the highest volume and tap my foot along with it to get the hang of it.

(I can't search the IOS app store but a quick google found these. It should be easy to find others)
I use Simple Metronome daily. No ads, just works every time.
