On your Home Screen

It looks like a habit tracker

Every kind of moment has a cover. Cuddling shows as Yoga, a deep talk as Read, a massage as Unwind. You see your month in dots, and nobody reading over your shoulder sees anything else.

Tap a tile to log it. There is a Control Centre button too, so recording a moment never means opening the app.

Why Silk

Silk, between us

Silk is a thread: fine, strong and close to the skin. The app is the thread through your moments together, from a long talk to a date night, so you can see the pattern they make.

Finding the words

Some things are easier to log than to say. murmur lets you say them out loud first: asking for more closeness, bringing up something new, or saying not tonight. Nobody hears it but you.

Questions

What is Silk?

Silk is a private log for intimate wellbeing. You record moments, mood and notes in one tap, and it shows patterns over time. Everything stays on your iPhone.

Can I log without opening the app?

Yes. Home Screen widgets log a moment in one tap. Each kind of moment shows under a cover such as Workout or Yoga, so the widgets read as a habit tracker.

Does Silk work for open relationships or polyamory?

Yes. Log per partner, aggregate, or solo mode. Pick whatever matches your setup.

Can I log mood or notes, not just frequency?

Both. Each entry supports mood, notes and tags alongside the frequency log. The calendar view surfaces patterns over time.
