LED tachometer strip or bar graph?

I'm thinking about doing something like this on a project (CB550).
All it lacks is a tach. Is there such a thing as a slim strip tachometer? Bar graph or LED strip that goes from green to red or something like that?

What app is that? i would like to test my phones accuracy when im driving

That looks good, sorry no info on strip tacho. I'm running a kosso lookalike that has led tach . Think it is great as I can see it when my face is too close to see needle
