Kasane DiaryA 3-year photo diary · with the weather
What did I wear the last time it was this warm?
A 3-year photo diary. Add one photo a day and the day's temperature and weather are attached automatically. Flip through today stacked with the same day in past years, and search your photos by temperature. Start by importing from your camera roll — in a few minutes, last year's today is already there.
Free, with a one-time Pro purchase for some features (Pro on Android is coming soon). iPhone, iPad and Android. English, 日本語, 中文, 한국어.
Short sleeves
or long?
The top of the home screen shows today's high, low and 8 am temperature, with photos from days that were about as warm. From the evening, it switches to tomorrow, so you can pick clothes the night before.
The same day,
every year.
Flip day by day with today and the same days in past years side by side — a week, a month, three months or a year. Watch your kids grow or your garden change in a few seconds, and share it as a video.
What did they wear
when it was this warm?
See photos from past days that were about as warm as today. Your own record becomes a guide for what to wear and when to switch seasons.
Temperature and
weather, added for you.
Just take or pick today's photo. Place, temperature and weather are added for you, in °C or °F. Today, last week, last month, last year and 2 years ago on one page. If there's no photo on that exact day, the closest day within 3 days is shown.
Start from your
past photos.
Import past photos from your camera roll and the temperature of each day is added afterwards (2 years free). Your 3-year diary starts on day one. Screenshots are skipped.
What will you stack?
Any photo works — one a day, each with its temperature and weather. When importing, choose kids, pets, sky and more under "What is this diary about?", and the import picks the matching photo from each day (Pro).

And more.
Pick the right photo for each day (Pro)
Choose kids, pets, sky, or "looks like this sample" (a garden bed, a houseplant, the view from your window), and the import picks the matching photo from each day. Photos are analyzed on your device only.
Send it to your family as a video
Turn a flip-through into a video, just as you see it on screen (stacked with past years, at your speed), and send it to family. Even a whole year fits in 5 minutes. You can also share a day's page as one image with the same day from past years.
Last time you were here
Pages from a trip show the pages from your earlier visits to the same place, so you can see how much the kids have grown since last time. Not shown for everyday places like home.
Pick a theme color
Choose your diary's color like picking a cover. Vermilion, Leaf and Sea are free; Mustard, Wisteria, Sakura, Chestnut, Ink and Night are Pro colors with gradients, also applied to shared images and videos.
Your photos stay on your phone
No account needed. Photos and records are stored only on your device and are never sent to a server.
Made for.
FAQ
Where are my photos stored?
Only on your device. Nothing is sent to a server, including when the app looks at what's in a photo (faces, dogs, sky, etc.). Deleting the app deletes your photos and records.
Where does the temperature come from?
Open-Meteo weather data. Your location is rounded to about 10 km before asking.
Some past photos have no temperature
If a photo has no location, the app doesn't guess. Pick a place (your home or a place name) on that day's page and the temperature is added.
There's no photo on the same day last year
The closest day within 3 days is shown, labeled like "2 days later". If there's none, the page is empty.
Why I built it
On the first cold morning of the season, I never knew whether to put my kid in long sleeves or short sleeves. I wanted last year's photos and that day's temperature in one place, so I built Kasane. I'm also improving it bit by bit, based on what parents and testers tell me.
I wrote about why I built it and what I fixed: Every year I forget what my kid wore last year, so I built an app.
