See a problem before it shows up
AI photo diagnosis plus Copilot correlations — VPD drift, temp extremes, DLI out of band — flagged automatically from data you're already logging.
An indoor grow journal · for solo growers
Know what actually changed your yield.
PhenoTrack logs your plants, environment, and photos, then tells you which changes actually moved the needle — not just what you did, but what worked.
One offline-first journal for tent-based growing: environment, plants, photos, and phenotype scoring, with AI-assisted diagnosis built in. No spreadsheet, no separate meter app, no guessing.

Copilot: VPD has drifted high for 3 days on this tent — worth checking before it stresses flower.
For the grower who wants to know why
Guessing is expensive. Especially indoors.
Temperature swings, feed changes, a new light — indoors, everything is a variable, and it's easy to lose track of which one mattered. PhenoTrack keeps one continuous, searchable record per plant so that next run, you're comparing data instead of memory.
What it actually does
Everything a single grower actually uses
No fluff, no social feed, no upsells.
Plan your lights before you buy them
Light Planning Studio: model PPFD and DLI against 141 real fixture spectra, then verify against a real canopy reading.
One tap to log, one place to see it all
Every log, reminder, reading, and photo on one searchable timeline — per plant, per tent, per run.
Compare runs, not vibes
Phenotype scorecards, harvest analytics, cost per gram — find your actual best performer across runs.
Stay on schedule without thinking about it
Care reminders, IPM treatment tracking with PHI/REI safety countdowns, and grow templates to reuse a setup that worked.
How it works
Three taps a day. One picture a week.
1
Log as you go
Water, feed, train, a quick note — seconds from the plant card.
2
Snap a photo
EXIF stripped automatically; diagnose with AI or just keep the record.
3
Check the trend
Copilot flags what's worth checking; the calendar shows everything in context.
AI, transparently. Diagnosis and insights are opt-in, and our privacy pages spell out exactly what each AI feature sends. Nothing you share trains anyone's models — and the journal works fully without AI.

FAQ
The things a skeptical grower asks
Does it work without internet?
Yes — local-first database on your device; cloud sync runs when you're online.
What happens to my photos?
EXIF (location, device) is stripped before storage. Photos are used for AI diagnosis only if you choose to — and never to train models.
Is the free tier a trial?
No time limit. The journal, environment monitoring, safety features and data export are free forever, with room for one growspace and four active plants; AI diagnosis includes 3 analyses a month. Pro removes the caps and adds the analysis layer.
Is there an iPhone app?
Not yet — Android and the web app are live today; iOS is on the roadmap.
