Stemma: Plant Tracker & Care

Lineage, Portfolio & Finance

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Stop Guessing. Start Growing with Precision. Whether you’re nurturing your first Monstera Albo or managing a diverse collection of rare aroids, Stemma provides the technical tools you need to track what actually matters: lineage, growth trends, and the financial value of your collection. I built Stemma because basic watering reminders aren't enough when you're dealing with high-stakes specimens. You need a way to track a plant’s history, its offspring, and its health with scientific accuracy. KEY FEATURES FOR THE SERIOUS GROWER AR GROWTH LOGS (THE "GHOST" VIEW): Create perfect time-lapses. When taking a growth photo, Stemma overlays a "ghost" of your previous image in the viewfinder. This allows you to line up every shot perfectly, so you can scroll through your logs and see exactly how that new leaf unfurled. VISUAL LINEAGE TREES: Never lose track of a cutting’s history. Map the genetic path from "Mother" to "Offspring" with clear, visual trees. Essential for anyone propagating rare variegates or tracking stable genetics across generations. FINANCIAL DASHBOARD: Treat your collection like the investment it is. Log purchase prices, track current market value, and monitor your ROI. Perfect for hobbyists who sell cuttings to fund their next "wishlist" plant. INTEGRATED LIGHT SENSOR: Stop guessing if your lighting is "bright indirect." Use your phone’s camera to measure exact Lux or Foot-candle levels right at the leaf surface. SUBSTRATE & LAB RECORDS: Keep a record of your custom soil mixes. Log which specimens are in "Aroid Gold," semi-hydro, or moss, so you know exactly what’s working for your specific environment. PERMANENT ARCHIVES: Keep the history of plants you’ve sold or gifted. Even after a specimen leaves your greenhouse, its lineage and care history stay in your records for future reference. ESSENTIAL TOOLS Action Logs: Record every watering and fertilization event. Custom Reminders: Set schedules tailored to your specific environment. Pro Exports: Generate CSV or PDF reports for your own tax records, insurance, or sales backups. Privacy First: Stemma is a local-first app. No accounts, no cloud tracking, and no data harvesting. Your photos and collection data stay on your device. From casual care to professional collection management, Stemma is the tool your plants deserve.
