Developer note from HCS Studio, the maker of Cora: Journal & Calendar. Cora brings dated journal notes, saved moods, period records, personal plans and water logs together on Android. You can add tags and search past entries. Weekly and monthly mood charts include only days with a saved mood; empty dates are left out. The calendar keeps recorded period days separate from estimates. A practical tip before changing phones: export a JSON backup from Profile and keep it securely outside the app. Restore purchases checks your Google Play PRO entitlement; it does not restore journal entries. A PDF is a readable export, not the JSON restoration file. Cora is free to download with ads and optional paid, auto-renewing PRO subscriptions. Google Play shows the available features, local price and renewal terms before you subscribe. Calendar estimates and water goals are personal planning tools, not medical assessments. We're happy to answer questions about the journal, charts or backup flow here. Please describe a problem without sharing private journal entries or a complete backup file.

Developer update, November 5, 2026: Cora 1.0.21 is available on Google Play. Through November 7 at 13:13 UTC, eligible accounts can get 25% off the first billing period of a weekly, monthly or annual PRO plan. It then renews at the standard price. Update Cora, open the app and, if the offer appears, check both prices on the Google Play purchase screen.
