Description by RIEKO NAITO Written by the developer, not by AppBrain. Click to read.
IPHONE DUO SUPPORT · SIDE BY SIDE
On iPad and supported foldables, pages adapt to available space, avoiding the fold. Large text or the keyboard can switch to one page. Add, time, edit and complete plans, five per narrow calendar page with no total limit. Diaries save automatically.

Calendar on the left. Diary on the right.
Open your day.

Plans and writing together. No sign-in or ads.

SIMPLE OR ADVANCED
Simple focuses on calendar and diary. Advanced groups tools in speech balloons: Record, Decorate & collect, Look back (a soft cloud), and Keep & print. Both share entries and keep hidden decorations saved.

PHOTO STAMPS AND A STICKER ALBUM
Make photo stamps with a date and optional note. Browse by month; tap for the full photo. The Eclat sample can be removed.
On wide screens, browse your collection on the left and preview one stamp on the right; narrow screens stack them. Share that stamp alone, without diary entries, plans or saved notes. Captions and hashtags are optional; dates start off. Included at no extra charge.
Shared images say “Decorative stamp · Not valid postage”. For mail, buy real postage at a post office or authorised retailer and attach the required amount. This is not a postal service; letter-paper and envelope creation are not included.

MEMORY POCKETS, HAIKU AND LOOKING BACK
Layer up to 12 photos in a translucent pocket; tap to see them clearly. On-device copies have a maximum 2048 px long edge; originals stay intact. Optional opening, adding and closing sounds.
Write your own haiku, short poems from Japan: vertical brush lettering in Japanese, horizontal otherwise. Line breaks stay; no syllable rules or scoring.
Make monthly or yearly collage PDFs with stamps, pockets and poems. Type new-year words with a brief introduction to Japan’s kakizome tradition; no handwriting input.
These features are included.

ACTIVITY MEMORIES
Write results, character growth and story progress, or check and import a compatible file. The sending app must support the format. This keeps a snapshot, without measuring exercise or advancing a game.

KEEP YOUR WRITING
Entries and photos stay on your device, not with the developer. Sharing sends only what you approve to your chosen destination. Writing and reading work offline; there is no automatic device sync. Text backup and restore cover diary, plans, travel writing, haiku, new-year words, pocket notes and activity text. Photos, stamp images, covers, purchases and settings are excluded. Restore preserves current photos and unrelated entries.
Print plans and diary by day or month on A4 or Japanese B5, with a left binding margin. Long entries continue on another page. Plain backgrounds save ink. Standard diary printouts omit photo stamps and covers; use a photo collage PDF to print memories with images.

MAKE IT YOURS
Rich leather-style covers accept art from compatible Museum Gacha versions in three frame sizes, with title, artist and source.
Optional diary stamps mark rest, walks or quiet days without removing your writing. Stamp sound starts off. Eleven themes: Original Paper and Temple Quiet included; nine separate one-time purchases. Finishing the day’s last plan plays a short theme sound, including a temple bell. Sounds can be turned off and respect silent mode.

OPTIONAL TRAVEL JOURNAL
A separate one-time purchase: destinations and plans beside one daily photo and notes, with multiple trips. Lodging or café notes add playful HP effects; religious sites add MP effects. These are not health measurements or religious promises. Finish with an optional fanfare and reopen a completed trip to add more. Preview and Restore Purchases available. No subscriptions; local prices apply.

Interface: Japanese, English, French, Spanish, Korean and Indonesian. Follow device language or choose in appearance settings. Your writing is not translated.
