Log how you feel

Tap your mood score, choose your emotions from curated categories, and optionally journal a few sentences. That's all it takes.

Watch patterns emerge

Weekly reports connect the dots between your mood, sleep, exercise, and habits — giving you a roadmap to feeling better.

✦ Dual AI Engine

Privacy-first AI.
Powerfully smart.

MoodQuill uses two AI engines. The default runs entirely on your iPhone using Apple Intelligence — zero cloud, zero data sharing. Upgrade to Pro for GPT-4o's deeper analysis when you need it.

  • Free & Plus — Apple Foundation Models Runs on your device. 100% private. No internet required. Instant responses with smart coached questions.
  • Pro — GPT-4o Cloud AI 128K context window. Multi-turn conversations. Deep weekly psychological reports and richer pattern analysis.
  • Always private by design Your journal entries and mood data are stored only on your device. We never see them. Even Pro only sends current check-in text — never your history.
