Why Pixy

Why people switch from MindDoc to Pixy

Pixy does one job well: it helps you notice how your days feel. Quick to fill in, clear to read, and private by default.

Your year in pixels

Every day becomes one colored square. A full year of moods fits on one screen, so patterns jump out.

Log a day in seconds

Pick a color and you are done. Add emotions, people, tags, or a note only when you want to. You choose which steps show up.

Name what you feel

Choose from a long list of emotions, each with a short description. Log as many entries per day as you like.

See who you spend your days with

Add the people you were with to an entry. Pick them from a grid of faces, or import them from your contacts.

Patterns you can act on

Each check-in ends with a summary of your day and your week in pixels. Monthly and yearly reports show when your mood peaks and which tags come up most.

A calm minute when you need it

Feeling anxious? After your check-in, Pixy offers short guided exercises: slow breathing, a worry check, or a body scan.

Your pixels on your Home Screen

iPhone widgets show your last 4 weeks, this month, or your whole year. Pick your mood colors and one of 9 app icons.

Private by default

No account and no sign-up. Entries stay on your phone. Export to JSON or CSV, or delete your data any time.

Open source, no ads

The code is public on GitHub under the MIT license, so anyone can check it. And nothing interrupts you: Pixy shows no ads.

    What MindDoc Users Ask, Answered for Pixy

    The most common questions in the MindDoc help center, and how they work in Pixy.

    • MindDoc help: “How much effort do I need to put into the app?”
      How often should I log my mood?

      Once a day is enough to see patterns. Log more often on days when your mood swings. A daily reminder helps you keep the habit.

      Read answer
    • MindDoc help: “Is my data secure and do I need an account?”
      Can the developer or anyone else read my entries?

      No. Your entries stay on your phone, so the developer cannot see them and other apps cannot read them. Anyone who can unlock your phone can open Pixy, so lock it if you share your phone.

      Read answer
    • MindDoc help: “Does using the MindDoc Companion replace treatment?”
      Is Pixy a replacement for therapy, and where can I get help in a crisis?

      No. Pixy is a self-reflection tool, not therapy or a medical device. If you are in crisis or think about hurting yourself, call your local emergency number or a crisis line right away.

      Read answer
    • MindDoc help: “What is the MindDoc Companion?”
      What is Pixy?

      Pixy is a free mood tracker and mood journal for iPhone and Android. You rate each day on a 7-step color scale, and Pixy paints it into a calendar, so a whole year of moods fits on one screen.

      Read answer
    • MindDoc help: “Where is my data stored?”
      Where does Pixy store my data?

      Only on your phone. Pixy has no account and no server that holds your entries. Your notes and tags never leave the device unless you export them.

      Read answer
    • MindDoc help: “Who created the MindDoc Companion?”
      Who makes Pixy?

      Pixy is built by Moritz Meyer, an independent developer. It is open source, and users shape what comes next by voting on features in Settings > Feedback > Vote Features.
