KittyCal – minimalist PWA calendar app for couples
Hi Fellow Hackers! I'm happy to share with you KittyCal, an installable calendar web app I made over the past two months. Existing calendar apps often focus on scheduling and require many steps to create one event. KittyCal, on the other hand, removes hourly scheduling and keeps everything on one screen. How does it work? Just enter your email address, and we will send you a pair of calendar links (blue and red). There is no login process, click the magic link or scan the QR code to access your calendar. You can then add the page to home screen and use it like a native app. Last year, I…
In plain words
KittyCal is a minimalist calendar web app designed for couples to share events and notes. Users enter an email address to receive a pair of personalized calendar links, then access their calendar via magic link or QR code without logging in. The app prioritizes simplicity by eliminating hourly scheduling and displaying all information on a single screen. It can be installed as a progressive web app on home screens for quick access, making it suitable for casual, everyday event tracking between two people.

Hi Fellow Hackers! I'm happy to share with you KittyCal, an installable calendar web app I made over the past two months. Existing calendar apps often focus on scheduling and require many steps to create one event. KittyCal, on the other hand, removes hourly scheduling and keeps everything on one screen.

There is no login process, click the magic link or scan the QR code to access your calendar. You can then add the page to home screen and use it like a native app. Last year, I built a bare bones version of KittyCal for my partner and myself because we wanted a private calendar that launches instantly for casual note-taking. It's worked well for us since, and I'm hoping this multi-tenant version can benefit more people with similar needs. Please try it out and let me know what you think!

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
