As answered by people managing HackerRank and FloHub.
FloHub's answer:
I hope that you will become one of FloHubs biggest users!
FloHub's answer:
Anybody who struggles like me in managing their work and personal lives whether that is schedules or content everywhere. Fantastic for people leaders, people with lots of family activities, thinkers and people who want to simplify their process flows
FloHub's answer:
FloHub was built to not replace peoples apps but to unify their content. Manage your day in one place and see at a glace what you've got planned. Supercharged with FloCat (AI) to give you helpful insights and suggestions rather than just doing work for you
FloHub's answer:
Other options are fantastic and could be useful for you, however, FloHub was built to be simple to use, with little to no learning curve and intuitive. It brings all the things you love and need and nothing more into one package without the need for additional addons
FloHub's answer:
Next.Js, tailwind, React
FloHub's answer:
I built FloHub because I could never find the right solution for me. I had used so many different note taking apps, task lists, but nothing ever stuck and the reason why is because things where still fragmented. I also had my work calendar and personal calendar. I would always miss things in the personal calendar and thus my wife yelled at me, so I wanted one place to see everything , tasks , habits, notes, journal. I also knew that im not perfect in how i work so i wanted some help in planning my day so widgets where created to help me with that
