Mainly Vaava (https://vaava.app) privacy-first baby tracker for feeds, sleep, diapers, and growth. Flutter, iOS and Android. Recently finished up e2ee data syncing for the paid tier of the app. Most recent relaese also contains some optional AI features. Got some real user feature requests which feels awesome.
Also working on https://fikalingo.com, basically replacing my current language learning app usage with that own made app. It has on-device based LLLm practice generation based on user given topic. For example word guessing practices can be created from a topic "words i might need as a auto mechanic". Only got to release the ios and web apps so far.
Mainly https://www.vaava.app/ is a baby tracking/logging app I originally built for myself, now available on both app stores. All the user generated data is stored only on device and is transferred in local network to users who you have paired the app with. There is 0 behavioural analytics, even the crashlytics are 100% optional.
There is a couple of semi-unique features; you can use your voice to dictate and generate events (feeding, sleep etc), you can also scan documents for growth measurements.
You don't need user account to use it, there is no subscription, the paid features are available behind a single purchase for lifetime. Still, like 90% of the features are available for free.

https://www.athilio.com/ privacy focused, highly customisable personal data analytics for your Oura, Garmin, Polar and Apple Health (ios port coming soon). Of course there is couple of AI features (with a single switch to turn all off), originally those were built just so I would learn how to embed agents in sw products myself. The whole app was originally built for personal use to fix missing features in the manufacturers own platforms:
- Period over period comparisons (this month vs this month last year)
- Comparing different metrics
- Customizable graphs and other widgets
- And of course combining the manufacturers metrics (oura for sleep, garmin for training etc etc)
Existing solutions for this kind of software seem to have focus on social (strava), or coaching (training peaks), or they are just straight up crazy expensive with their paid tier (both tp and strava for example).
Thanks! Yeh focusing on privacy is good differentiator, large established players just cant really compete in that area in a similar manner. It also reduces operational load from myself when I dont hoard user data. And of course the customer gets a service that respects their privacy. But when focusing on privacy there needs to be adjustments and compromises on UX and such in some areas, but you got to so say no to somethings when sticking to your values!

Also https://www.athilio.com/ , which originally was also purely for my own use. Most sports and fitness wearable manufacturers own software and 3rd party software make it incredibly hard to do "how does my this months metric x compare to same month last year", athilio attempts to make those queries easier. Many of the ideas are basically copied from software observability concepts. Also I have used the app to implement and learn agentic workflows.

Currently finishing up garmin integration and a mobile port of the app.
The app is aimed at people with goals related to their wellness or sports / training. Somewhat similar to training peaks but more focused on integrating different metrics, like sleep and readiness from oura and training data from garmin. Also user has more control. 0 focus on social features. Pricing aims to be affordable (1/4 - 1/2th of similar services), this is hopefully possible with local first approach for the data(sqlite). Saves tons of money on the backend costs when only the syncing from integrations + oauth is on the backend and no storage. Also I think this is more friendly for the users privacy and I would prefer to not store the users datas on my servers for GDPR reasons. Syncing between user devices can be done similarly as Obsidian with icloud. The user experience is a bit influenced by software observability.
