I had been getting frustrated with my calendars recently and decided to go back to a basic calendar.txt file, only to miss my calendar being available everywhere. Naturally, I over-engineered a solution to that problem and built an app that edits like a text calendar, but is otherwise available on all of my devices and everywhere that I am - online or offline.<p>Feel free to give it a try - <a href="https://txtcal.app" rel="nofollow">https://txtcal.app</a><p>You can create a calendar, edit it, add some basic labels like the day of the week and week number, and export it to a plain old text file or continue to use it online.<p>Lately, I've been really into building small, single purpose tools for myself, and figured I'd try sharing this one. I'm certainly open to feedback. I have no idea if anyone has this same problem or wants to use it, but if it catches on, I'll probably build it further. I do have a longer term goal of selling super inexpensive, simple to use apps, with the goals of being feature-complete and without enshittification over time. Maybe this will be the first of those with some premium features later, but I intend to keep this basic version free.<p>For anyone interested in the tech stack, it's pretty boring and I like it that way. It's written in Python with Flask, uses Postgres, emails with Sendgrid (might finally go past the free tier here) and is self-hosted with Dokku on a Digital Ocean droplet. Claude Code probably cut my dev time by 75%.<p>I'm sure there are some bugs to iron out. I can say with certainty that it does not look great on mobile yet, but that'll come next.
