A period tracker that lives only on your iPhone.

Hey HN, after the app I actually used to track my period wanted me to log in and save my data in the cloud, I decided to write my own. Most apps in this area are based on a subscription model and display far too much information anyway. For me, a simple calendar is enough where I can add a few notes if necessary. So that is the result of my work - a simple design and the data is only saved on the smartphone.

I kept trying to explain how important outdoor light is and how most people aren’t getting enough. Eventually I figured that showing is more effective than telling. So we built a free app that uses your Apple Watch or iPhone to automatically track your light exposure throughout the day. It tells you if you’re getting enough, shows you how consistent you are, and rewards habits that support hormone balance. It's in beta on TestFlight, let me know what you think!

There’s something quietly unsettling about how normal it's become to hand over our most personal data to apps that barely deserve our trust. My wife once showed me a notification she got from her period tracking app. At first, it seemed like a simple reminder. But then came the ads. Not long after, she started getting eerily specific suggestions on other platforms. Things she hadn’t searched for. Things that felt too close. Somewhere, her cycle had been turned into a data point. That bothered me more than I can explain. These apps promise helpful insights. But in return, they take so much.…

Hi everyone I'm a Notion-addicted person and love to build my own template to cover different aspects of my life, either work or personal stuff. Once, I wanted to build a habit tracker template, and I realized Notion was not the best solution. You can organize it in a much more efficient way just with a pen and a piece of paper. However, the best tool should live on your devices and have a correct structure. Then, I decided to try to build an app using SwiftUI and SwiftData. The goal was to make it a very basic version in one month. But it took me two months. I tried to add only the core…

I've often wondered whether there are any patterns or cycles to my moods so I built a simple iPhone app that occasionally pings me to ask how I'm feeling on a scale of 1 - 10. I also note down what I'm thinking or doing at that moment and automatically grab my location. I use the data to show some basic statistics on how I've been feeling on average over the past three days, past week and since I started tracking. There's also a graph of my moods over time. I'd love to get feedback on whether people would find something like this useful. I'm curious about what other things people would want…
