Sentinel Den – Zero-back end, on-device iOS security SDKs
On-device security audits with <2ms overhead for regulated iOS apps.

Local-first wellness tracking respects privacy; lacks polish and features competing apps already offer.
Privacy-conscious individuals tracking mood, stress, health metrics, and wellness patterns

I wanted a place to store my own info and share it on my own terms. For example, I might want to share that I'm feeling good with friends, or bring a summary of my blood pressure readings to a doctor's appointment. The main concept is personally owned data collation rather than handing everything off to a third party. Also, I think recording stats in a place other than a notes app would allow for better analysis and visualisation options in the future.
I do want to develop this app further, and am keen on understanding what others would want from a tracking app.
Potential use cases: Tracking wellness to mood Having data from multiple sources being personally organised and managed Sharing customised info/stats
The big players in this space sometimes trade privacy for polish. I wanted something where the tradeoff goes the other way. More polish will come to StatusHealthy (I think that could be better).
Critical feedback would be appreciated. What is a feature of such an app that would want you to check in regularly? I am eager to hear any thoughts. Thank you.
