--- title: The week my calendar app stopped being just mine description: >- Calendula was a thing I built for myself. Then strangers started relying on it, filing issues, debating design in the comments — and it turned into something with a small community around it. pubDate: 2026-07-03 tags: [open-source, calendula] draft: false --- I built Calendula for myself. I wanted a fast, good-looking, privacy-respecting calendar that didn't own my data, couldn't find one, and so I made one. For a while that was all it was: my app, my phone, my taste. Then people showed up. Not many, not all at once — but enough, in about two weeks, that the project stopped feeling like a thing I *have* and started feeling like a thing I'm *responsible for*. This is a note about that shift, because nobody tells you how quickly it happens. ## From requests to a rhythm The first issues were classic solo-dev fare: someone asked for a setting to choose which view the app opens on. I shipped it in [v2.9.0](https://codeberg.org/jlmakiola/calendula/issues/1) within hours, and "that was quick!" came back. Then a tappable month grid; then a Saturday week-start — each one small, each one turned around fast. Then: limit the agenda view to today, or this week, or the next 30 days — and here the exchange got interesting, because I stopped just building the literal request and started asking *what options would you actually want*, and we designed it together in the thread. That rhythm — report, discuss, ship, "thank you" — is the engine of a small open project. It's also a trap if you let it: not every request should be built. The hard skill isn't saying yes fast, it's [saying no well](/blog/the-feature-i-said-no-to), and keeping the app inside its [lane](/blog/open-standards) while the person still leaves happy. ## The moment it gets real There's a specific sentence that changes how you feel about a side project. Mine arrived on an issue about registering an intent filter, from someone who'd hit a papercut on GrapheneOS: > I have been looking out for a well-designed and fast calendar since switching > to Android four years ago and your software seems to be on point. Four years of waiting. That's the kind of line that reframes a side project — someone who's been holding out for exactly this and is ready to depend on it. The same thread is where I admitted a limitation honestly (there's no Android API to set yourself as the default calendar, so no in-app button is possible — only the system picker), and that honesty landed better than a workaround would have. Relied-upon software is built on trust, and trust is mostly just not overpromising. ## When users become co-designers The real tell that a community is forming isn't traffic — it's when people start doing the *thinking* with you, not just the reporting. On a request to make the view quick-switch button configurable, the conversation turned into an actual design debate: should reordering live in a settings tab, or should you long-press and drag items in place? Would drag-in-place cause accidental reordering? We went back and forth on the interaction, not the feature. On the contact-birthdays feature, a user who *wasn't even the original reporter* created test contacts — one Google, one CardDAV — to help me isolate why some birthdays showed up and others didn't. That's not filing a bug. That's debugging *with* me. I don't have a big community. I have a handful of people who care about a good calendar as much as I do, and who've started treating its rough edges as *our* problem. That's the shift. ## The unglamorous parts, on purpose None of this is a highlight reel. In the same fortnight I shipped a release that mangled the month widget's switching buttons — a regression a user caught and I had to go dig out of a recent change. The birthday feature still doesn't handle every account type. Writing this, I could have quietly left those out. But the point of doing this in the open, on a public tracker, is that the reasoning and the mistakes are all readable — the terse "closed" label replaced by an actual conversation anyone can follow later. A project stops being *just yours* the moment someone else would notice if it broke. Calendula crossed that line quietly, in a week of issue threads, and it changed how I write every commit since. The question stopped being "does this please me" and became "would I want to explain this decision to the people in the comments." The second one is the one worth answering.
