Your diaries and replies stay on this device. Speech transcription and AI replies are processed on your device; preparing the models for the first time may require an internet connection. Recordings are removed after you review and save the transcript. You can save and restore encrypted backups in a Files folder of your choice. Premium offers automatic backups while the app is open and unlocked. Sign-in and real-time sync are not available.
Diary storage, reminders, and manual backup and restore are free. The free plan includes three AI replies per week. Premium includes daily AI replies, related memories, new reflections and automatic backups. Check prices and trial eligibility on the Apple purchase screen.
AI replies require an Apple Intelligence compatible iPhone and a ready model. Availability depends on language, device, operating system and model readiness. You can save your diary even when AI is unavailable.
DayReply is for everyday journaling and general emotional support. AI may misunderstand your situation. The app does not provide diagnosis or treatment. Reach out to someone you trust or a professional when you need help; contact local emergency services if you are in immediate danger.
Subscriptions renew automatically. Annual plans are billed as a single annual payment. Manage or cancel in Apple subscription settings.
