About this app

■ Fav — a daily book for the things you love

Write today's poem. Rank your favorites. Build a collection that is entirely your own.
Fav brings three small pleasures into one app, with a calendar that ties them all to the days you lived them.

Everything is stored on your device. No account, no sign-up, and every feature is free.

──────────────────
✍️ HAIKU — written the way you actually write
──────────────────
Fav does not assume that haiku means 5-7-5. You choose, poem by poem.

• 5-7-5 — the traditional form, with each line counted for you
• Free form — short-long-short, the way most English haiku are written today
• A syllable counter that shows how each line is running, and lets you correct it by hand when it disagrees with you
• A dash button for the cut (kireji) — the pause that sets two images against each other
• Senryu, tanka and one-line monoku are all at home here
• 256 English season words, each with a short note: first frost, dawn chorus, long shadows, thaw day
• Northern or Southern hemisphere — set it once and the seasons follow you

Writing in Japanese instead? Every Japanese feature is still here: over 500 traditional kigo with readings and meanings, makura-kotoba, and proper vertical writing for Japanese poems. Fav is fully bilingual — switch the whole app between English and Japanese whenever you like.

Finish a poem and Fav lays it out as an image: your words, a photo behind them if you want one, a date, and a red seal with your pen name. Save it or share it.

──────────────────
🏆 BANZUKE — rank anything, sumo style
──────────────────
The banzuke is the ranking chart of Japanese sumo, and it turns out to work for absolutely everything.

• Ramen shops, songs, hot springs, cats — anything you can list
• Type the names in order and Fav assigns the ranks: yokozuna, ozeki, sekiwake, komusubi
• East and west sides are worked out for you
• Save the finished chart as an image and share it
• Add a poem to the chart, and it is printed there too

──────────────────
📚 COLLECTIONS — your own illustrated catalog
──────────────────
• Photograph and note the things you find, one at a time
• Merchandise, trading cards, manhole covers, insects, plants, places you ate — the subject is up to you
• Set a target number and watch the completion bar fill
• Add things you want but do not have yet, and use it as a wishlist
• Rate each item, record when and where you got it, and what you remember about it

Inside every collection there is also a scrapbook. Stick photos in, resize and rotate them, crop them square, rounded, circular or star-shaped, draw on them by hand, set a two-color background, and add text boxes for a diary entry, a quote or a lyric. One page at a time, it becomes a book.

──────────────────
📅 THE CALENDAR IS HOME
──────────────────
Poems, rankings, collections and scrapbook pages all land on the day you made them. Open a date and read it back like a diary. A quiet streak counter keeps track of the days you showed up.

──────────────────
🌏 ENGLISH OR JAPANESE, YOUR CHOICE
──────────────────
Every screen, message and reminder is available in both languages. Switch in Settings at any time — your poems and collections are untouched, and Japanese poems keep their vertical writing even while the app is in English.

──────────────────
🔒 YOUR DATA STAYS WITH YOU
──────────────────
• Everything is saved on your device only — nothing is sent anywhere
• No account, no login, no cloud
• Export everything, photos included, and import it on your next phone
• Free, supported by a single banner ad
Write haiku in 5-7-5 or free form, rank anything, and grow your own collections.

What’s new

■ Fav is now fully in English
Switch the whole app between English and Japanese in Settings. Screens, notifications and season words all follow.

■ Write haiku in English
Choose 5-7-5 or free form for each poem, with the syllables counted as you type.

■ 256 English season words
One arrives each morning, with a line to start you off. Northern or southern hemisphere.

■ Fixed
The banzuke now matches a real sumo ranking sheet: yokozuna on the outside, lower ranks toward the middle.
