About

Seiri

Features
Read full description

Inspired by the Japanese 整理 (organize) — the first step of the 5S method, popularized in the West by Marie Kondo. Most address books grow for years and never get cleaned because the task feels too big to do all at once. Seiri makes it one decision at a time. WHAT SEIRI DOES • One contact at a time, three decisions: discard, keep, favorite • Swipe the card or tap a button — your choice • A local trash holds discarded contacts for 30 days, so nothing is lost by accident • Restore brings a contact back with full fidelity (photo, addresses, related people, social profiles, notes) • Permanent delete clears the trash record when you are sure • Light, dark, and system appearance • 8 languages: English, Portuguese (Brazil), Japanese, Spanish, French, German, Italian, Simplified Chinese PRIVACY • Zero collection • Asks for one permission: Contacts (read and write) • No account, no backend, no analytics, no third-party SDKs, no network requests • Your address book and your decisions stay on your iPhone Made by FALL Engenharia. Proprietary software, distributed free under Apple's standard EULA.
