Scheduling user interviews became 10x faster (and cheaper) after switching to Cal. Many links, all customizable, I still don't know how it's free. I used to use Calendly before, and even tried Google Calendar in between for a bit – but Cal wins for simplicity.

Cal is an amazing tool that saves me so much time manually scheduling onboarding calls. I have even started using their video calling solution as it's browser based, and super easy to use!
