We built an uncomplicated calendar tool for low-fidelity planning
My partner and I do a lot of planning around things like holidays and trips, which involves a mix of firm, tentative, and overlapping plans, and normal calendars are the wrong fidelity for that kind of planning. We often found ourselves drawing on top of screenshots of calendars with tools like Miro or even printing out calendars we could draw on. We're both product designers, and so we're used to working in low fidelity tools like Excalidraw and FigJam. We decided to try and make a low-fidelity equivalent for calendars, and built Walnut.

What it does
In the maker’s words, at launch
My partner and I do a lot of planning around things like holidays and trips, which involves a mix of firm, tentative, and overlapping plans, and normal calendars are the wrong fidelity for that kind of planning. We often found ourselves drawing on top of screenshots of calendars with tools like Miro or even printing out calendars we could draw on. We're both product designers, and so we're used to working in low fidelity tools like Excalidraw and FigJam. We decided to try and make a low-fidelity equivalent for calendars, and built Walnut. It's just lines and stickies, with a few different styles, no events or times. Walnut has two versions: the super simple, localstorage-based version at letswalnut.com, which you can just pop open any time. There's also a "workspace" version which lets multiple people work on the same calendars with multiplayer collaboration, and persists the calendars long-term. It's still rough around the edges and needs more design refinement, but we've been using it extensively personally (and my team's using it at my work for planning purposes). It's not right for everyone, but for those who like to plan this way, we think it's helpful. Curious to hear any thoughts! Right now anyone can use the localstorage-based version. If you'd be interested in trying out the persisted/collaborative version, drop your email in the waitlist[1] and I'll send you an invite to sign up!

I love the looks and UX of the Google calendar. But I wanted to have a version I could use more freely in my own projects, still looking similar to the one from Google.

Inspired by Minimal[1] and Netnik[2] printable calendars, I wanted a way to fit as many habits on a single sheet of paper as possible. This is very much a work-in-progress, so beware of bugs. I will flush it out over the next few days. Happy New Year, everyone! [1] https://useminimal.com/habit-tracker [2] https://neatnik.net/calendar/

Hi HN, I built a tiny tool because I couldn’t find a clean, distraction-free monthly planner that: 1. shows a clean monthly task view 2. doesn’t require an account 3. doesn’t sync or store anything online 4. works offline 5. is printable 6. and keeps a minimal, distraction-free aesthetic So I made https://printcalendar.top/ — a minimal monthly task planner. It’s intentionally simple. No logins, no integrations, no dashboards. Just a small tool for people who want structure without clutter.

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
