Questions & Answers

As answered by people managing Open Devdocs and AnnuCal.

How would you describe the primary audience of your product?

AnnuCal's answer:

Visual planners, freelancers, families, and small teams and agencies who juggle many projects, trips, and goals across the year - including people who plan in spreadsheets today and want a clearer, more visual way to structure time. They value clarity, focus, and privacy, and want to make better decisions by seeing the full year at a glance.

What's the story behind your product?

AnnuCal's answer:

AnnuCal started with a simple idea: What if we could see our whole year at once?

Tired of cluttered monthly views and scattered planning tools, we built AnnuCal to bring clarity back to yearly planning. Created in Germany by a small independent team, AnnuCal was designed to be clean, calm, and privacy-first - a calm, time-first alternative to overloaded calendars

Who are some of the biggest customers of your product?

AnnuCal's answer:

  • Individuals, employees, freelancers & small business owners
  • Creative professionals managing multiple projects
  • Small agencies & project teams
  • Families and remote teams planning vacations & workflows

What makes your product unique?

AnnuCal's answer:

AnnuCal is a time-first year planner, not another calendar. Instead of weekly or monthly views, it shows your entire year on one screen - so you can spot phases, overlaps, and free space at a glance. You mark time first (click or drag across the year), then add the details. Switch between Linear, Vertical, and Weekend views, plan in separate scenarios, and share or embed your full year - with public and school holidays built right in. GDPR-compliant and hosted in Germany.

Why should a person choose your product over its competitors?

AnnuCal's answer:

Most calendar tools focus on short-term scheduling - the next meeting, the next day. AnnuCal helps you see the bigger picture and plan time realistically across the whole year. You can share individual calendar tabs or your full year, and even embed the entire year into other websites and team pages. Plus it's GDPR-compliant, ad-free, and hosted in Germany, so your data stays private while your planning stays simple.
