CoupleLog – No-Signup iCloud Couple Diary

Private, no-signup couple diary with pure iCloud sync

Problem

The user built a couple's private diary app that requires no sign-up, emphasizes privacy (no data collection, iCloud-based sync) and longevity (local-first). Most journal apps require accounts, collect data, or rely on third-party servers, raising privacy concerns for couples sharing intimate moments.

Solution

An iOS couple diary app that needs no account; data stays local and in iCloud, synced between partners via iCloud sharing. Supports text, photos, videos, voice, drawings, mutual comments, and 'on this day' memories.

Users

Privacy-conscious couples, partners wanting a long-term relationship journal

MVP

No-account local diary; iCloud sharing for two-person sync; text, photo, voice support; mutual comments; simple calendar and search; free tier with limits, paid unlock for unlimited entries

Revenue

Freemium: free 30 entries/month, in-app purchase for unlimited entries, high-res images, video (annual $19.99 or one-time $39.99)

Why now

Growing concern for privacy and data ownership; iCloud sync tech is mature; indie developers can build an iOS app quickly with no server costs.
