DayVo vs Diktafon

DayVo is a voice memo and diary app for iOS and macOS that turns speech into searchable text in real time. You can search recordings and edit, copy, or share transcripts. Transcription supports English, Chinese, Japanese, Korean, French, and Spanish. Recording can pause and resume while remaining one continuous session. DayVo exports recordings as PDF summaries for ChatGPT, Claude, Notion AI, and other AI tools; iCloud and email sharing are also listed. The maker says recording, transcription, search, and insights run on-device, with no data collection or content sent to its servers, and that core features work offline. The Free plan costs nothing, includes core features, and requires no account. Premium costs $2.99 a month or $25 a year, adding advanced AI insights and enhanced export. The App Store listing requires iOS 17.0 or later or iPadOS 17.0 or later. Accuracy depends on audio quality, speaking clarity, and language.

Diktafon is a voice memo app that transcribes and summarizes recordings on the device, then groups them into topic-based cassettes. It uses Whisper for transcription and Qwen for summaries; the models download on first run and can be changed in Settings. Each memo’s spoken language is detected, so recordings in different languages can sit in one cassette. Tap a transcript word to jump playback to that point in the recording. Cassettes can be exported as archives with audio and readable text, and imported content is added without overwriting existing items. The privacy policy says recordings, transcripts, summaries, labels, and settings remain in private app storage, and that the app collects and shares no data. Its stated network activity is limited to model downloads over HTTPS from Hugging Face and its CDN at the user’s request. The project is designed by Jaromír Janisch and is free and open source, with support for Android, iOS, Linux, and macOS.
