Cora: Journal & Calendar

We are HCS Yazılım, the developers of Cora: Journal & Calendar. Cora is an Android app for keeping dated journal entries, saved moods, personal plans, period records and water logs together. Write or edit a day, search entries and filter by tags. Weekly and monthly mood charts count only days with a saved mood: missing entries are not treated as negative results. The calendar keeps manually confirmed period records separate from estimates. Water logs support ml and litres, a personal goal and optional reminders. Light and dark themes are available. Personal records stay on the device, with user-managed backup and export options. Advertising and Google Play purchases use online services separately. The app is free to download with ads and optional paid, auto-renewing PRO plans. Google Play displays local pricing and any eligible trial terms before confirmation. Calendar estimates and water goals are planning aids, not medical advice. We welcome feedback on recording a day, understanding the charts and finding the next action. Screenshots show the real app with illustrative entries. Android download: https://play.google.com/store/apps/details?id=com.cora.period
