A private app is not the same as a private-looking app.
Most of what we say about privacy is about what happens after you open AsterKit: no accounts, no cloud, no ads, nothing about your cycle ever leaving your device. That part matters most. But there is a smaller, more physical kind of privacy too: what the app looks like sitting on your home screen, or open on a desk, or glanced at over your shoulder on the bus. A tracker that looks like a tracker invites questions you might not want to answer.
That is the thinking behind Theme Studio, a new screen we just added to make picking a look faster and a lot more visual.
See all six looks before you pick one
AsterKit has shipped six themes for a while now, but changing between them meant opening a list and imagining what each one would actually look like. Theme Studio replaces that with a grid of live cards. Each one is rendered in its real colors, real type, and real contrast, not a small swatch standing in for the real thing. You can see Coral Studio next to Midnight Observatory next to Citrus Market all at once, and tap any card to apply it instantly.
Open Settings, then Theme Studio, to try it.
Match your phone, or don't
If you would rather AsterKit just follow your phone's light or dark mode, a Match Device Appearance toggle sits above the grid. Turn it on and the app tracks your system setting automatically. Turn it off and pick any of the six looks yourself. Neither choice is more correct than the other; it is just there for whoever wants it.
Why the look is not just decoration
A period tracker that looks calm, or dark, or bright and busy, is a period tracker that does not visually announce itself as one. For a teenager whose phone gets picked up by a friend, a sibling, or a parent glancing over, that matters in a way that is easy to underestimate. You should not have to think about who is nearby before you open an app to log something about your own body. A theme you actually chose, one that looks like the rest of your home screen, makes that a little less likely to come up at all.
None of this changes how your data is handled. Your cycle history still lives only on your device. There is still no account, no server, and no copy of it anywhere but your phone.
Try it
Open Settings, then Theme Studio, and tap through all six. If one of them looks like you, it takes one tap to make it yours.
