Sotto — Gentle people notes for the details that matter
Everyone carries little details worth remembering. Sotto keeps them safe for you — heights, preferences, the things only you would know. All data stays on your phone, quietly helping you remember.
Designed for the People You Care About
Simple, gentle, and yours alone
A Question to Open With
Stuck for what to ask? Pick one from a curated catalog — a fresh note opens prefilled with the question, ready for their answer.
Question catalog informed by Aron's 36 Questions (1997), Gottman's Love Maps, NYT's 13 Questions, Gary Chapman's The 5 Love Languages (1992), and the curation shared by Threads user hey.roseline.
A Page for Every Person
Create a little world for each person you care about — photos, bios, and the details that make them who they are.
Never Guess a Size
Height, shoe size, a ring size for every finger — 23 size and measurement fields, so you never have to secretly ask before buying a gift. Ring sizes convert between seven systems, shoe sizes between five.
The Look You Love
8 carefully crafted color themes, light and dark, so every screen feels like yours.
These Are Your Secrets
Everything stays on your phone — no account, no ads. Lock the app with your phone's own screen lock (Face ID, Touch ID, fingerprint or passcode), and back up only to your own cloud, only when you choose.
Write Down What Matters
Their favorite coffee, her anniversary, something they once said — jot it down so you never forget.
