iPhone
Speak your day into a private diary. Use Japanese or English voice input, or type in Thai. Your diary stays on your iPhone. One purchase, no subscription.
Turn your day into a private diary by speaking or typing. VocaLog reduces the friction of journaling and keeps your memories on your iPhone.
■ Speak to journal in Japanese or English
Apple's on-device speech recognition turns your voice into text. When you choose AI formatting, an on-device Llama 3.2 model shapes it into a readable diary entry. Type instead when you prefer a quiet moment.
■ Thai interface and text entry
Use the interface in Thai, type Thai diary entries, review and edit them, and keep the original text on your device. Thai voice input and Thai AI formatting are not available in this version.
■ Private by design
Diary text, photos, voice, and people data stay on your device. After the model is prepared, Japanese and English AI formatting runs on your iPhone. Model download is optional.
■ Make reflection easier
Capture moods, categories, tags, photos, calendar entries, people context, and spelling preferences. Review the original transcript whenever you want.
■ Three-day trial, one-time purchase
For new users, the three-day free trial starts when the first diary is saved successfully. After the trial, one purchase unlocks all features permanently. No subscription. The current local price appears on the purchase screen.
Requirements: iOS 17 or later. iPhone 15 Pro or later is recommended for on-device AI.
