Call Memory is a "second memory" for your phone calls. After an important call, the user writes a short note. The app attaches it to a person the user created inside the app, builds a per-person timeline, and shows a "before you call" card with follow-ups that surface on their due date. Core features: manual text notes, per-person timeline, follow-ups (optional local notification on the due day from version 1.2), search across people, phone numbers, notes and follow-ups, editing of people and notes, drafts, backup to a file and restore from a file (from 1.2), 11 interface languages from 1.2 (English, Turkish, German, Spanish, French, Italian, Portuguese, Arabic, Russian, Japanese, Korean). Monetization: the first 20 notes are free with no time limit. Call Memory Premium is an optional auto-renewing subscription (weekly, monthly, yearly) for unlimited notes, sold through Google Play. Prices come from Google Play and are never hard-coded. No ads, no account, no login. Permissions: INTERNET, com.android.vending.BILLING and ACCESS_NETWORK_STATE (Google Play purchases). From 1.2, only if the user turns follow-up notifications on: POST_NOTIFICATIONS, with RECEIVE_BOOT_COMPLETED and WAKE_LOCK so a set reminder survives a restart. The app does NOT read the call log or contacts, does NOT record audio or calls, does NOT use the microphone on Android, the camera or location. People inside the app are typed in by hand.
