Calendar on the left. Diary on the right.
Open a two-page view of your day.
LEFT / RIGHT is a simple notebook for checking your plans and writing about your day.
SIDE BY SIDE
Keep your calendar and plans on the left and your diary on the right. On iPad and other larger displays, enjoy a roomier spread.
When large text or the keyboard leaves too little room, the selected page can use the available space.
A narrow calendar page shows three plans at a time. Tap Next to see more and First to return to the beginning. This display does not limit how many plans you can save.
11 NOTEBOOK THEMES
The original warm paper is joined by Moonlit Carnival, Nightmare Candy, Neon Atami, Cyber Rococo, Digital Green, and other designs, for 11 themes in total.
Temple Quiet is available at no additional charge. Its tiled eaves, timber details, calm paper, and brush lettering bring a quiet setting to your daily notes.
The original paper and Temple Quiet are included with the app. The other nine themes are optional, separate one-time purchases. No subscription is required. Prices are shown in your local currency. Use Restore Purchases with the same Apple Account to restore purchased themes.
Changing a theme keeps your saved plans and diary entries intact.
A SOUND FOR COMPLETING YOUR DAY
When a day has at least one plan, checking its last unfinished item plays one short sound for your chosen theme. Temple Quiet uses a temple bell.
Completion includes all plans for that day, including plans on other pages. Turn Completion sound off in the appearance settings; your choice is remembered. The sounds respect your device's silent setting.
IPHONE DUO SUPPORT
On a supported foldable device, the pages adapt to the available space and avoid the fold. Pages may be arranged above and below each other depending on the fold direction. In a small available area, the selected page is shown.
