Products that do what I made a privacy friendly and simple app to track my menstruation does
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.

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.…

The private period tracker that grows with every cycle

After decades of tracking my exercise programs in progressively more complex spreadsheets I eventually burned out on metrics and complicated periodization programs to the point where I had almost stopped exercising. I am now at a place where I simply want the minimal amount of structure and tracking to make sure I can maintain my fitness, so I boiled the entire concept down to what I felt was its essence: enough information and structure to remind you of what is needed today, and how it went on the same exercises last week. To reduce friction, the interface is kept as simple as possible.…

Hello. I was looking for a simple and clean habit tracker. I went through a few apps but felt they were missing something. I also had some time on my hands, so decided to make my own and share it in case anyone else likes it. Some of the supported features: Streaks based, track and beat your longest streaks Fully useable offline Freezes (similar to Duolingo's streak freezes) Visual map for tracking consistency Pause the app when you need a break or will be away For anyone curious about the tech stack: - React for frontend - Dexie cloud for storage and syncing - Vercel for hosting Link:…

Hey HN! I made TimeAnt because my dad needed a simple way to track his time at work and he didn’t like the other apps out there because they were too complicated or had way too many features. So, I built an app that just does the basics: track work hours, meetings, breaks, lunch and optionally lets you add notes - and that's it. It’s totally free, works both online and offline, and doesn’t require an account (but you can create one if you want). The goal was to keep it super simple and let you focus on tracking time without all the fluff. It also gave me a chance to learn Swift and build my…

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!

I've been running Simpluna, a period-tracking app, for six years. It's a company based in Tokyo, Japan, but development and operations are basically a one-person effort. The app is built with React Native (Expo). The defining trait of the app is that it's simple, with no unnecessary features. Recording periods, calculating predictions, and sending notifications — that's the core of it. This space is dominated by big players (Flo, Clue, and in Japan, Luna Luna). Building something similar would have been hopeless, so I made the things those apps don't have my selling point. Optional features…

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…

My Expenses is a very simple app to track expenses for one-time budgets. Let's say you're going on vacations in Italy and you want to allocate $1.500 to this trip. You create a budget "Italy" in 30 seconds and you're ready to go. Each time you make an expense in Italy, you add it to the app in a few seconds and you instantly know you're remaining budget. I'm bored of super complex apps. Yes, they do a lot of things, but it often takes a while to get used to the app and understand all its features. That's why I created this app. I want people to be able to track their expenses in seconds, as…
