I’ve spent the last 90 days testing 3 leading calendar apps: Apple Calendar, Vimcal, and Outlook. This isn’t another feature list comparison—it’s a founder-focused analysis of what actually works in real workflows.
Bottom line first: Each tool serves different needs. Here’s my recommendation based on your situation:
- Choose Apple Calendar if you need icloud sync and work as apple users ($0 free)
- Choose Vimcal if you need speed focused and work as busy professionals ($15/month)
- Choose Outlook if you need microsoft integration and work as enterprise ($6.99/month)
Why This Comparison Matters
Most calendar app reviews chase features. Founders care about ROI, adoption friction, and whether this tool actually ships value. I tested each app in real workflows, tracked time saved, measured onboarding friction, and evaluated long-term viability.
For indie hackers, solo devs, and small teams building products—not just collecting tools.
