Seedline: Seed Saving Journal

Seedline is a personal seed-saving journal for home gardeners.

Which plant did last year's tomato seeds come from? How old are the lettuce seeds in the drawer? Did they germinate well last time? Seedline links it all together: parent plant → saved seed batch → storage → germination trial → next generation. No sign-up needed, and your records stay on this device.

■ Seed batches — keep every harvest separate
· The same variety becomes a separate batch when its harvest date, source or storage differs.
· Record variety, crop, generation, harvest date, quantity, storage location and method, and notes on the parent plant and pollination.
· Search, filter by crop, and sort by newest harvest, name or lowest quantity.

■ Seed lineage — from parent to next generation
· Link each batch to one parent batch and follow every generation from the starting batch on one screen.
· A batch can't be its own parent or descendant, so the lineage never loops.
· A batch with linked children can only be deleted after its links are changed.
· Lineage is your record of where seed came from. It does not prove genetic purity or the pollen parent.

■ Germination trials — accurate, cumulative observations
· Record the number of seeds tested, start date, temperature, medium (paper towel, seed-starting mix…) and status.
· Each observation records the cumulative number germinated so far; values lower than before or dates before the start are rejected.
· The combined rate across trials is total germinated ÷ total tested. 9 of 10 plus 9 of 90 is 18% — not a simple average of 50%.
· A comparison table lines up variety, harvest date, temperature, medium and rate.

■ A 124-plant library
· 44 vegetables · 24 herbs · 30 flowers · 16 fruit · 10 houseplants.
· 106 plants have a representative image (some are botanical illustrations), each with its author, license and source link. The rest are marked "photo coming soon".
· Search and filter by category, season, propagation, favorites or photos.
· Each plant shows where to start recording and what to check. Tap [Record] to start a batch with the tips filled in.

■ Find what to grow with the weather
· Location is requested only when you tap [Get weather for current location]; you can search for a place instead.
· See current conditions and a 7-day forecast (low/high, chance of rain, wind).
· Choose where you grow and your light, and get candidates with reasons and what to check. Indoors uses the temperature you enter.
· Cold, heat, rain and wind are flagged; forecasts older than 6 hours are never used.
· Suggestions narrow down candidates with published rules. They don't guarantee germination or harvest.

■ Backup, export and labels
· Full JSON backup and restore (seeds, lineage, trials, observations, favorites) is always free. The records just before a restore are kept once so you can undo.
· Export your seed list as CSV for spreadsheets.
· Print labels for seed packets or save them as PDF.

■ Free · Watch an ad · PLUS
· Free: up to 20 seed batches, plus everything else above.
· Watch an ad: 5 more batch slots per ad (up to 15) · CSV and labels for 24 hours · a 24-hour PLUS trial once a week.
· PLUS (monthly or yearly): unlimited batches · germination curves · A4 label sheets · no ads.
· Over the free limit you can still view, edit and back up your records. Cancel anytime in Google Play.

■ Privacy
· No sign-up or login, and your seed records are never sent to a server.
· Only when you check the weather, coordinates rounded to two decimal places or the place name you searched are sent to the weather provider (Open-Meteo). Coordinates are never stored or backed up.
· Free users see non-personalized ads by default.
