Diktafon vs Lightning Voice

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.

Lightning Voice is an iPhone app for scheduled voice reminders. It sends a local notification when a reminder is due, then lets you open the reminder and play its recorded note. Titles are optional when a recording exists. Scheduling offers quick presets, a full time picker, and weekday repeats. On-device history records heard and missed reminders. A Home Screen widget shows the next reminder, while Control Center and Siri can open New Voice Reminder on supported systems. Reminders and recordings remain on the device without cloud sync or a required account; the microphone activates only when recording starts. The app requires iOS 17 or later and lists English and Simplified Chinese. Notification delivery follows iOS settings, so Focus, mute, Low Power Mode, or denied permission can limit alerts. The free plan allows 10 enabled reminders; Pro starts at $0.99 per month.
