Your records.
Your choices.

Moods, journal entries, chats, runs and long-term memories are primarily stored on your device. Local recording works offline without an account. Export a backup before changing devices.

Backups contain sensitive content and are not automatically encrypted. The app does not provide its own cloud diary sync.

AI, when you choose.

After explicit consent, chat with AI or turn a conversation into a diary draft or summary. Requests go through the developer's HTTPS backend to DeepSeek and require internet access.

Optional mood, diary, memory and profile context is off by default and can be controlled separately. AI replies can be inaccurate. The app does not provide medical diagnosis, treatment or professional counseling.

Manage AI permissions

Free recording. Optional AI allowances.

Pulse Plus adds more AI chat and generation allowances. Monthly and annual plans have the same benefits.

Free and Pulse Plus comparison
Features and allowances	Free	Pulse Plus
Mood, diary, running, weekly review, search, favorites, app lock and local backups	Included	Included
AI chat turns per month	30	600
Diary drafts and chat summaries per month (shared)	3	60
First-use bonus on this device	20 chat turns + 2 generations	Available without subscribing

Allowances reset each UTC calendar month and do not roll over. An annual plan does not grant a year's allowance at once. A turn is one message and one valid reply. Diary drafts and summaries share the generation allowance; regenerating uses another generation. Failed requests are not charged and automatic retries are not charged twice.

United States: $2.99 per month or $24.99 per year. Mainland China: CNY 18 per month or CNY 128 per year. Prices elsewhere and final charges are shown on Apple's in-app purchase confirmation.

Subscriptions renew automatically and Apple processes payment. Cancel renewal in system subscription settings; access continues until the paid period ends. Existing records remain available to view and export.
