The problem
A growing season is easy to lose track of
A season is long, and the details that decide your harvest are the first things to slip.
Missed treatments
Forgot when you last fertilised? Plants suffer and yields drop when care is inconsistent.
Lost records
Paper notes disappear. Spreadsheets get messy. You can't remember what worked last season.
No insights
Without data you repeat mistakes, with no way to compare varieties or improve yields.
The solution
One journal for the whole growing year
Siy keeps the record for you — from the first seed to the last basket — so nothing depends on remembering.
Never forget a treatment
Set a reminder when you log the work. Siy notifies you on the day, straight from your phone.
Every record in one place
A single timeline of plantings, treatments and harvests — filterable by plot, exportable whenever you want.
Learn from last season
Compare varieties and yields year over year, and stop guessing at what actually worked.

How it works
Three steps, then it maintains itself
Set up once at the start of the season, and the journal maintains itself from there.
Create plots
Add your garden beds, greenhouses or growing areas and give each one a name and a colour.
Track actions
Log plantings, treatments and harvests as you go. Attach notes and set a reminder in the same step.
Get insights
Review the full history, export it wherever you like, and plan the next season from real records.
Features

AI plant diagnosis
PremiumPoint your camera at a sick plant
Yellowing leaves, spots, wilting — describing it to a search engine rarely helps. Show it to Siy instead and get a specific answer while you're still standing in the bed.
Photograph the problem
Take a shot of the affected leaf, stem or fruit — or pick one from your gallery.
Get an answer in seconds
Diseases, nutrient deficiencies and pests identified, with severity and what to do next.
Saved to your planting
The treatment plan is saved to the planting it's for, with reminders for each step.
