What is DailyVox?
DailyVox is a free AI voice journaling app for iPhone and iPad. You speak your thoughts and DailyVox transcribes them on-device using Apple's Speech framework. It also uses on-device AI to detect your mood, build a Digital Twin of your personality, and generate weekly insights — all without sending any data to the cloud.
Is DailyVox really free?
Yes, completely. DailyVox has no subscriptions, no in-app purchases, no ads, and no premium tier. Every feature — voice journaling, AI mood detection, Digital Twin, personality cards, encrypted backups, and export — is included for free. Compare that to Day One ($34.99/yr), Journey ($29.99/yr), Reflectly ($59.99/yr), or Daylio ($23.99/yr).
How does voice journaling work in DailyVox?
Tap the record button and start speaking. DailyVox uses Apple's Speech framework to transcribe your voice into text in real time, entirely on your device. When you finish, the app saves both the audio and the transcription as a journal entry. You can also edit the text afterward or add photos.
Is my data private in DailyVox?
Yes. DailyVox processes everything on your device. There are no servers receiving your data. Your voice recordings, transcriptions, photos, and Digital Twin model never leave your phone. Apple has verified this with a "Data Not Collected" privacy nutrition label on the App Store. See our Privacy Policy for details.
Does DailyVox work offline?
Yes. Recording, transcription, mood detection, and all AI features work fully offline. The app uses on-device models that run on Apple's Neural Engine, so no internet connection is needed. Speech transcription accuracy may be slightly better online, but offline accuracy is still very good.
What is the Digital Twin in DailyVox?
Your Digital Twin is a private AI model that learns from your journal entries over time. It picks up on your personality traits, emotional patterns, communication style, values, and personal knowledge. After enough entries, it generates personality cards and can predict your moods. The Digital Twin stays 100% on your device and grows more accurate the more you journal.
How does mood detection work?
DailyVox uses Apple's NaturalLanguage framework to analyze the sentiment and emotional content of your journal entries on-device. It classifies entries into 9 mood categories and tracks patterns over time. The mood detection runs automatically after each entry and requires no manual input, though you can adjust the detected mood if you disagree.
Can I export my journal data?
Yes. DailyVox supports exporting your journal in multiple formats: PDF, JSON, Markdown, CSV, and plain text. You can also create password-protected encrypted backups using AES-256-GCM encryption. Go to Settings > Export Data to choose your format.
Do I need to create an account to use DailyVox?
No. DailyVox requires no account, no sign-up, and no email address. You download it and start journaling immediately. If you want to sync across devices, you can optionally enable iCloud sync, which uses your existing Apple ID — but this is entirely optional.
What devices are supported?
DailyVox runs on iPhone and iPad with iOS 17.0 or later. It is optimized for both devices with a native interface that adapts to different screen sizes. There is no Android, web, or Mac version at this time.
How is DailyVox different from Day One?
The main differences are price, privacy, and AI. DailyVox is completely free while Day One costs $34.99/year for premium features. DailyVox processes all data on-device with no cloud servers, while Day One syncs data through their servers. DailyVox includes AI features like a Digital Twin and mood prediction that Day One does not offer. Day One does support more platforms (Mac, Android, web) and has a longer track record.
Is it safe to journal private thoughts in DailyVox?
Yes. DailyVox was designed specifically for private journaling. Your data never leaves your device, encrypted backups use AES-256 encryption, and you can lock the app with Face ID or Touch ID. Since there are no servers, there is no risk of a data breach exposing your journal. Apple's privacy label confirms "Data Not Collected."
What happens if I lose my phone?
If you have iCloud sync enabled, your entries will be available on any other Apple device signed into the same Apple ID. If you have exported encrypted backups, you can restore from those. Without either, your journal data exists only on the device. We recommend enabling iCloud sync or regularly exporting encrypted backups as a safety measure.
How does on-device AI work without the cloud?
DailyVox uses Apple's built-in machine learning frameworks — NaturalLanguage for sentiment analysis and named entity recognition, Speech for transcription, and Core ML for running models on Apple's Neural Engine chip. These frameworks are optimized to run efficiently on-device without needing an internet connection or cloud processing.
Can I use DailyVox without speaking (text only)?
Yes. While voice journaling is the primary feature, you can also type entries directly. You can write text-only entries, or record voice and then edit the transcription. DailyVox's AI features work on the text regardless of whether it was typed or spoken.
How many mood categories does DailyVox track?
DailyVox tracks 9 mood categories. The AI automatically detects your mood from each journal entry, and you can view mood trends over time through weekly insights. You can also manually adjust the detected mood if you feel it does not match your actual state.
What are personality cards?
Personality cards are insights generated by your Digital Twin after it has analyzed enough journal entries. They describe aspects of your personality, values, communication style, and emotional patterns that the AI has identified. Cards become more detailed and accurate as you journal more frequently.
Does DailyVox support iCloud sync?
Yes. You can enable iCloud sync in Settings to sync your journal entries across your iPhone and iPad via Apple's CloudKit. Your data is encrypted with your Apple ID. iCloud sync is optional and disabled by default.
