I built a text-based birthday reminder app
I bought the birthdays.app domain a few years ago and decided to build a simple birthday app, just text message reminders. I had hacked together a duct-tape version for myself a couple years prior (using zapier + google sheets), and found it useful. It was a pain sifting through Facebook birthdays (90% irrelevant), and I found the text reminders simpler than a calendar. The app has been slowly growing since 2023, and is now up to 739 paying users (mostly on the $9/yr plan, with a few paying $3/yr). Earlier this year, I built a Google Calendar integration to automatically sync…
In plain words
Birthdays.app is a text message reminder service for birthdays. Users log in via phone number and can input birthdays manually, by text, or by syncing their Google Calendar. The app sends SMS notifications on birthday dates and avoids the clutter of social media birthday lists. It requires no download and operates as a web-based service, focusing on simplicity and functionality without ads or engagement tactics.

In the maker’s words, at launch
I bought the birthdays.app domain a few years ago and decided to build a simple birthday app, just text message reminders. I had hacked together a duct-tape version for myself a couple years prior (using zapier + google sheets), and found it useful. It was a pain sifting through Facebook birthdays (90% irrelevant), and I found the text reminders simpler than a calendar. The app has been slowly growing since 2023, and is now up to 739 paying users (mostly on the $9/yr plan, with a few paying $3/yr). Earlier this year, I built a Google Calendar integration to automatically sync birthdays to the app. My goal is birthday reminders without the baggage a normal "social" app would have such as ads, engagement bait, etc. I call it an app, but there's actually no app to download. Users log in via phone number + sms login code, then input birthdays manually, via text, or via Google Calendar. At the moment, US users receive SMS messages (which are cheaper to send in the US), while other countries receive WhatsApp text reminders. The app uses Twilio to text users (both SMS + WhatsApp) and Stripe for payments. I'm hoping to build more features (iPhone contacts sync, easier birthdays importing) while also making video content that celebrates strangers' birthdays (such as, going to a farmers market with an "is it your birthday?" sign). Thank you for reading, I'm open to any thoughts or ideas around the app!

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
