FAQ
Pixy vs Diarium: frequently asked questions
Diarium is a private diary app. Pixy is a mood tracker that turns each day into one colored pixel, so a whole year of moods fits on one screen. Pixy also offers a year in pixels calendar and on-device storage, which Diarium does not list in its store description. Diarium lists voice notes, device sync, health data such as sleep, photos in entries, and automatic backups, which Pixy does not have.
It depends on what you need. Pixy fits if you want a quick daily check-in and a year in pixels, with no account. Diarium fits better if you want voice notes, device sync, health data such as sleep, photos in entries, and automatic backups.
Pixy has no direct import from Diarium. Most people keep an export of their old Diarium history and start fresh in Pixy. You can export a Pixy backup file at any time.
Pixy is made for mood tracking. Every day becomes a colored pixel, and statistics show when your mood peaks and which tags come up most.
Your mood on a color scale, emotions from a long list with short descriptions, the people you were with, tags for activities and places, and a note. You decide which steps show up, and you can log several entries per day.
Your entries stay on your phone. Pixy needs no account and no sign-up. You can export a JSON or CSV file or delete your data at any time. To keep a copy automatically, turn on Backup in Settings > Data > Backup. Pixy then saves one backup file in your own iCloud or Google Drive. It is off until you turn it on.
In Pixy, open Settings > Data > Backup, turn off the switch, and tap Turn Off. Pixy deletes the backup file from your iCloud or Google Drive. On Android, Pixy also signs out of Google Drive. Your entries on the phone stay. Delete All My Data does not delete the cloud backup, so turn off the backup first. Lost your phone or deleted Pixy? On iPhone or iPad, open Settings > [your name] > iCloud > Manage Account Storage (older iOS: Manage Storage) > Pixy > Delete Data from iCloud. On a Mac, open System Settings > Apple Account > iCloud > Manage > Pixy. For Google Drive, open drive.google.com on a computer, click the gear, then Settings > Manage apps > Pixy > Options > Delete hidden app data.
Not at the same time. Pixy does not sync entries between devices. The iCloud or Google Drive backup holds the entries of one phone. To move to a new phone, restore the backup there. Restore replaces the entries on that phone. When two phones use the same backup, the phone that wrote it last keeps it. The other phone pauses its backup.
