How many calendar apps do you open every morning? (Be honest)
I'll go first
I was opening three. Google Calendar for work, iCloud for personal, Outlook for a side project. Every single morning, I'd flip between all three just to figure out if I was free for a coffee chat at 2 PM.
The worst part? I'd still double-book myself because I forgot to check one of them.
That frustration led me to build CalUnity, a free app that pulls all your Google, Apple, and Microsoft calendars into one unified view across iOS, Android, and web.
I recently shared it on one subreddit and our user base grew 250% in 12 hours — turns out a lot of people share this exact frustration.
We're launching here on Product Hunt on May 5th, and before that I'd genuinely love to hear from this community:
— How do you currently manage multiple calendars?
— What's the most annoying thing about your current setup?
— If you could fix one thing about how calendars work across providers, what would it be?
I'm a solo developer building this in public, and your answers will directly shape what I work on next. Not trying to pitch — I actually want to build what people need.
