Features
One photo a day
A guided three-step flow children can manage on their own: snap a photo, write one line, done. Keeping a daily observation diary has never been easier.
Weather recorded automatically
Every entry is stamped with the day's weather and temperature — no more guessing what the weather was on day three.
From diary to report in one tap
Choose a template and the whole journal organises itself into a printable report — a classic poster-style sheet or a page-a-day notebook — ready to export as a PDF in A4 or A3.
Widgets and streaks
A home-screen widget shows today's "observed / not yet" status and your streak, with a gentle daily reminder at whatever time suits your family.
Growth charts
Add optional measurements such as height or count, and watch them grow into a chart across the whole observation period.
Pay once, keep it forever
The free version covers one theme. A single one-off purchase unlocks unlimited themes, every template and watermark-free PDFs. No subscription, ever.
The hardest part of a school observation project isn't the observing — it's keeping it up every single day, and then turning a huge pile of photos into something your child can actually hand in.
KansatsuLog sorts both. Each day your child snaps one photo and writes one line, and the app stamps it with the day's weather and temperature automatically. When the project is finished, choose a template and the whole journal organises itself into a beautiful report — a classic poster-style sheet or a page-a-day notebook — ready to print or hand in as a PDF.
ONE PHOTO A DAY
- A guided three-step flow children can manage on their own: photo, one-line note, done
- Weather and temperature are recorded automatically — no more guessing what the weather was on day three
- Optional measurements (height, count, or anything you like) build a growth chart over time
MADE FOR REAL SCHOOL PROJECTS

- A home-screen widget shows today's "observed / not yet" status and your streak, so no day gets missed

FROM DIARY TO REPORT IN ONE TAP
- Poster-style layout: the full observation period on one big printable sheet, perfect for the classroom wall
- Notebook-style layout: one page per day, like a proper field notebook
- Add a title, a name and a closing summary, then export as a full-colour PDF in A4 or A3
- A summary assistant drafts the closing paragraph from your child's own entries, so getting started is easier
WHY PARENTS LOVE IT
- Children do it themselves — no need to sit beside them for every step
- The streak gently builds a habit of sticking with things day after day
- Run several observations at once: one per child, or plants and insects side by side
- Brilliant for science homework, holiday projects, or simply a lovely family routine
