24 alternatives to I made a privacy friendly and simple app to track my menstruation
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.
This is a menstrual cycle tracking app designed for simplicity and privacy. It provides a basic calendar interface where users can log their period and add notes, with all data stored locally on the device rather than… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I made a privacy friendly and simple app to track my menstruation launched in 2024; newer entries below may have overtaken it.

Simpluna▲68I'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…

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.…

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.…

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…
