Silk
LayeredAdd Moment
Toys and details on each moment
Pick who was there, add the toys you used and set the mood. Kinks and positions sit in the details.
What you did, and how it felt
A moment in Silk holds who was there, what happened, the toys you used and the mood it left you in. In the details you can add kinks from Silk's list, from rope and impact play to role play and power exchange, or write your own.
A note takes the rest: what worked, what to change, what to ask for next time.
Limits and interests, per partner
Each partner's page keeps what they are into and where their limits are. Interests include sensory play, bondage and power dynamics. Boundaries include no marks, consent check-ins and aftercare needed, and safe words sit with how they like to communicate.
With more than one play partner, it saves relying on memory before a scene.
What is still on the list
The Exploration page in Insights sorts everything into tried and not tried yet, and marks what you or a partner put on your lists. It is a quiet way to see what to bring up next.
The days after
Mood has its own entry in Silk. If a low tends to follow an intense scene, log your mood on those days too. Next to the moment, it is easier to see when it arrives and to plan aftercare around it.
Nothing on the Home Screen gives it away
On the widgets, role play shows as Games, a fantasy as Evening and a new experience as Highlight. The log stays on your iPhone with no account, and the app icon can be swapped for one that reads as Notes or Weather.
Next to the apps for a dynamic
Apps such as Obedience run a dynamic between two phones, with habits, rewards and punishments. Silk does a different job: it remembers what you did, on one phone. See Silk vs Obedience and Silk vs Embrace.
Free and Premium
Silk is free with one partner. Toys, kinks and positions on a moment, more than one partner and the Exploration page are part of Premium.
Insights
Exploration and Toys
Exploration shows what you have tried and what you have not. Toys plots each toy by how often you use it and how those moments felt.

A cover on every widget
Every kind of moment has a cover, so the widget reads as a habit tracker.
Questions
Is there a private app to log BDSM scenes?
Yes. Silk logs a moment with who was there, the toys you used, kinks from its list or your own, your mood and a note. It stays on your iPhone with no account.
Can I keep a play partner's limits in Silk?
Yes. Each partner's page holds their interests and their boundaries, such as no marks, consent check-ins and aftercare needed.
Does Silk have tasks, rules or rewards for a D/s dynamic?
No. Silk is a log of moments on one phone. Nothing is assigned and nothing is shared between phones.
Will the widget show what I logged?
No. Widgets show covers: role play appears as Games and a fantasy as Evening.

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.
