Phenotype tracking & cultivar journaling
Find your keeper.
Score every pheno. Cull the rest. The pheno-hunt companion that keeps the record and does the math, so the standout is obvious.
Finding a keeper shouldn't come down to memory and a messy notebook. PhenoLog keeps every pheno, score, and observation in one place and lines them up, so the standout is easy to see.
Everything you need
Run the whole hunt
Every hunt you've got going in one place, with status, search, and a tap into the run. Start from seed or cutting and keep them all side by side.
Open a hunt, see every pheno
Each pheno numbered and tracked from seedling to harvest. Add phenos, set the flip date, and jump straight into any plant's record.
Score traits week by week
Walk each pheno through seedling, veg, flower, and processing. Log observations every week so nothing gets remembered wrong.
Score the finish, not just the grow
Rate the finished product too: structure, shape, color, grade, and aroma intensity. How it cured counts in the final call.
Compare phenos side by side
Pull two or three together. The strongest in each trait pops, and the composite score makes the winner obvious.
Let the data pick the keeper
Six traits, one composite, every pheno ranked. AI Keeper turns a season of scoring into a verdict you can actually defend.
Pro
AI Keeper names the keeper
Tap Analyze and AI Keeper reads the whole hunt, then lays one pheno's strength across all six traits as a web, with its verdict and confidence right up top.
Pro
Overlay any two phenos
Tap a pheno from the ranking to drop it onto the web and compare shapes head to head. The bigger footprint usually wins.
Pro
The whole hunt as a scorecard
Every pheno against every trait in one color grid. Strong cells glow green, weak ones go amber, and the pattern jumps right out.
Pro
See where the keeper pulls ahead
Trait by trait, every pheno plotted on its own lane, so you can see exactly where your standout separates from the pack.
Your genetics library
Every cultivar you grow, filterable by seeds, mothers, and archive, with lineage and source on each.
Track mothers and clones
Open a cultivar to see seeds remaining, clones taken, the hunts it's in, and its photos. Promote a keeper to a mother and follow it across seasons.

Built by a grower
I use PhenoLog on every hunt I run.
PhenoLog wasn't built by a software company guessing at what growers need. I'm Matt Cohen. I've spent 15+ years in commercial controlled-environment agriculture, with a B.S. in Agriculture from the University of Hawai‘i. I've directed cultivation across 50,000 sq ft facilities, built tissue culture labs and clean-stock programs from scratch, and run more cultivar selections than I can count.
I built PhenoLog because my own hunts were drowning in spreadsheets and notebook scribbles. Every feature in the app exists because I needed it in my own grow.
Want something the app doesn't do yet? Tell me. A real person reads every message, usually the same day, and the roadmap is shaped by what growers ask for.
