Show HN: Dexter – an opinionated day planner for Mac

https://dexterplanner.com/
17•cvburgess•1y ago
Hey HN, Dexter is a day planner I built for Mac (and web).

This was a grief project. Some people make art when they're soul searching, and making apps has always been a bit of an artistic outlet for me. Earlier this year my mother committed suicide and two weeks later the company I worked for laid off my entire division. After taking some time to grieve and process I started building something just for me, just for fun, just because I wanted to.

Dexter has been a slow project that started as paper sketches at my kitchen table and slowly morphed into a codebase. It allowed me to play with tools I wanted to get better at like Postgres and Typescript while also letting me try (and in some cases fail) experimenting with new-to-me tools like Tailwind, Supabase, Tauri, Electron, and Vite.

Small portions of the app and site were "vibe coded", but 99% is hand-crafted code (not necessarily good code), graphics, and data models. This was meant to be a fun project where I learned things just because I wanted to learn something, not a race to see how fast I could grind out a product.

For an example of "unnecessary but fun", I made each SVG on the marketing site twice with Figma - once in a light theme and again in a dark theme - so if you toggle your OS's dark mode, everything should change, even the images.

A few things about the app:

- Yeah, I know, it's an Electron app. I tried using Tauri and other tools but hit a few snags. The Electron ecosystem was incredibly mature and easy to use in comparison

- The app is open source [0] and so is the marketing site [1]

- Some friends and I have been using it daily for a few months and really enjoy it compared to our old multi-tool workflows

- Dexter is the name of my 12(?) year old husky, hence the dog branding

- There is a pricing widget on the marketing site but the app is currently totally free. I might integrate Stripe soon if (and only if) that feels like a fun project, but the goal isn't to get rich or even turn a profit, it's to have fun and build something genuinely useful that I use every day

There are a bunch of features I would love to add and enhancements I would like to make, and eventually I will. Currently, I pick up a feature just because it sounds fun that day and I put it down when it is no longer fun. It might not be a good business model, but it has been a wonderful antidote to an industry rife with burnout and a personal life that's been a little out of control.

I hope you enjoy it and maybe build something for yourself, just because it sounds fun.

If anyone gives it a try I will be in the comments today and happy to answer any questions!

Sorry to hear about the inspiration for this. It's very nicely done. Great work.
cvburgess•1y ago
Thank you so much <3
DevDad_io•1y ago
Very clean UI, well done!
cvburgess•1y ago
Thank you!

I got to dust off some old UX skills that haven't been used in a few years.

Huge shoutout to DaisyUI [0] and tailwind for making it really easy to build pretty things.

DevDad_io•1y ago
Ha! Daisy and Tailwind are so wonderful, I used the same for my app. I especially like the multidirectional scrolling on your app.
cvburgess•1y ago
Scrolling has been the bane of my existence lol.

Im pretty happy with it currently, but want to fix a small annoyance where columns can "hijack" horizontal scrolling.

I learned SO MUCH about CSS tools of old and new doing this project. The popover API and anchor positioning in particular was a bit of a beast, as were overflows and scroll areas.

Most of my background has been in native or react-native mobile development where these kinds of issues don't really exist in the same way.

Going back to basics with html + css was humbling and taught me a lot, too.

I came across this randomly when I searched "Figma" on HN, and I'm very glad I did. Tastefully done app -- wishing you all luck in the world.
