This year's seedlings, next to last year's.
Plantlet is a journal for people who start plants from seed. Every tray gets a short code, a growth stage and a timeline of notes and photos. Next season, line your batches up week by week and see what changed.
Sign in with Google or email. Works in your phone's browser; add it to your home screen like an app.
A spreadsheet works until the notes pile up.
One row per batch is fine on sowing day. Then every check-in becomes another column, the photos live somewhere in your camera roll, and by June you can't tell which tray was which.
Plantlet keeps each note and its photos on the batch they belong to, in order, with the day count since sowing worked out for you.

How it works
-
Add what you grow
Type a variety, or copy one from the catalog with sun, spacing and days to maturity filled in.
-
Start a batch per tray
Each planting gets a three-letter code to write on the label. Split a batch when half goes outside or to a neighbor; both keep their history.
-
Snap a photo at the bench
Tap +, pick the batch, and the camera opens. Add a line about what changed. Move it through stages from seeded to harvest.
-
Compare seasons
Open a plant to see every batch you've grown of it by year, then line any of them up by weeks since sowing.
Made for the phone in your hand at the seed shelf.
Big buttons, the camera one tap away, and nothing to install from an app store. On a laptop the same account opens up into a wider layout for planning next season.
- Install it to your home screen on iPhone or Android
- Notes stamped with the day since sowing
- Dark mode, matching your phone
- Batches due for a check-in, and what you were doing this time last year
Trialing varieties or growing for others?
Seed testers and small nurseries run the same loop at a bigger scale: many lots, splits, germination counts, and comparisons against last year's results. Plantlet's batches, codes and splits already fit that work.
If you grow at that scale, tell us what would make it useful. Lot tracking, exports and shared accounts are on the table, and early users shape what gets built.

Questions
What does it cost?
Nothing during the beta. The first 25 accounts are founding members and won't be charged for Plantlet's core features, ever. If paid plans arrive later, everyone gets at least 30 days' notice and nothing you've recorded gets locked away.
Is there an app to download?
Not from an app store. Plantlet runs in your phone's browser. On iPhone, tap Share then Add to Home Screen; on Android, tap the menu then Install app. It opens full-screen with its own icon.
Does it work without a signal?
Not yet. Plantlet needs a connection to load and save. If your seed-starting spot has no coverage, take photos with your camera and add them to a note later; you can set the note's date and time when you save it.
Can I bring my spreadsheet?
Not automatically yet. If you have one you'd like to move over, email support@plantlet.co. Knowing what columns people use decides how the importer gets built.
What's a batch?
One planting of one variety: a tray of 12 Sungold tomatoes sown on September 24, a row of carrots, a cell pack of basil. Each has its own code, stage, quantity and location, and its own timeline.
