Founder's Note
I built 0Cal after getting fed up with back-and-forth emails — especially when someone needed to send over a file before a meeting. Scheduling shouldn't be this hard — especially on mobile.
0Cal is my attempt at fixing that. It's fast, clean, and designed to work for real people — not just sales teams.
If that resonates, I'd love your feedback as we keep building.
