Who you spend time with
Moments and satisfaction by person, month by month.
Per person, or all together
Each moment is logged with whoever was there. Insights can show one partner or everyone at once, with moments and satisfaction by person.
Looking after everyone
A partner's page holds their preferences, important dates, pronouns and allergies, and when they were last tested. It is easier to be considerate when you are not relying on memory.
Sexual health across partners
Protection, STI tests and medications sit next to your moments, so the question of what happened before or after a test has an answer.
Free and Premium
Silk is free with one partner. More than one partner is part of Premium.

Can my partners see my log?

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.
