Sotto is a private notebook for remembering the people you love, not a CRM for managing them. Keep sizes, allergies, favorite things, dates, relationships, and notes in one place, with 100+ built-in fields. Pick a Question offers 323 curated prompts to help you go beyond small talk, then save what you learn to that person's page. Personal details stay on-device by default, protected by biometrics, with optional backup to your own cloud account.
