Best Pokemon Go Evolution Calculator

[anotherplayer]

What do you think is the best Pokemon Go evolution calculator? I personally use https://www.pokego.org/evolution-cp-calculator/ but wanted to double check if there's a better tool for calculating how much Combat Power (CP) each Pokémon gains when it evolves.

i use https://www.evolvecalculator.com I tested a few times. It's pretty good. It gives you Max CP. if it says 1220 CP, you can sure your pokemon's CP between 1150-1200 CP.
