One photo a day
A guided 3-step flow kids can do on their own: snap a photo, write one line, done. Keeping a daily observation journal has never been this easy.
Weather logged automatically
Each entry is stamped with the day's weather and temperature — no more wondering what the weather was on day 3.
From diary to report in one tap
Pick a template and the whole journal lays itself out as a printable report — a classic poster-style sheet or a page-a-day notebook — ready to export as a PDF.
Widgets and streaks
A home-screen widget shows today's "observed / not yet" status and your streak, plus a gentle daily reminder, so no day gets missed.
Growth charts
Add optional measurements like height or count, and watch them build into a growth chart over the observation period.
Pay once, keep forever
The free version covers one theme. A single one-time purchase unlocks unlimited themes, every template, and watermark-free PDFs. No subscription, ever.
The hardest part of a science observation project isn't the observing — it's keeping it up every day, and then turning a pile of photos into something you can hand in.
KansatsuLog fixes both. Every day, your child snaps one photo, writes one line, and the app stamps it with today's weather and temperature automatically. At the end, pick a template and the whole journal lays itself out as a beautiful report — a classic poster-style sheet or a page-a-day notebook — ready to print or submit as a PDF.
