Anchor Spoken Memory.
Speak Naturally with Confidence.
PhraseEcho is designed for natural voice capture, phrase organization, and adaptive EchoFlow spaced repetition. Core learning stays on-device; optional backups, speech resources, and AI features connect online only on demand.
Local-First Architecture
Your phrase libraries, review history, and core repetition routines stay on your device. Optional iCloud backups, voice pack downloads, and AI translation assistance access the network on demand.
EchoFlow Adaptive Review
Intelligently schedules review opportunities based on continuous mastery and cooling protection, presenting phrases right when reinforcement is most effective.
Speech Input & Natural Audio
Converts spoken phrases into text via system speech recognition, pairing your practice with native device or app-level text-to-speech engines.
Strict Language Isolation
Supports 18 canonical languages with dedicated partitions. Libraries, review queues, and progress statistics never cross-contaminate across learning languages.
Open Data Portability
Full JSON backups and standardized CSV imports allow you to export, archive, and transfer your study materials smoothly between Android and iOS without vendor lock-in.
Modern Native Craft
Built with Jetpack Compose (Android) and SwiftUI (iOS) for fluid performance, low resource footprint, and seamless platform interaction.
Transparent, Reliable, and User-Respecting
PhraseEcho does not operate proprietary user accounts, advertising networks, usage tracking, or centralized cloud upload servers. When you choose to enable optional third-party integrations, data is processed strictly according to our transparent privacy policy.
