Pros: It's focused only on OKRs and does that job very well. Other platforms include e.g. 1-on-1 feedback and coaching functionality, which makes implementation more difficult. Perdoo was easy to get started with and it works well across the teams.
Pros: I like that for me, as an inexperienced OKR-user I'm quickly able to learn how to implement these goals in my daily routine using Perdoo.
Pros: It is OKR 100%, compared to other softwares that are more complete, but more complex as well
