Peloria: Plant Light Meter

All-in-one care for 391 plants. Measure light, get a species verdict, then track watering, feeding, humidity, and a photo journal. One-time ad removal, no subscription.

Most plant apps guess at light. Peloria gives you a calibrated, repeatable reading - then helps you care for the rest. It is an all-in-one home for 391 plant species: measure the light at any spot, get a species-specific verdict, then track watering, feeding, repotting, humidity, and a photo journal, all in one place.

MEASURE THE LIGHT

• Pick your plant, point your phone at the spot, and measure.
• A guided 3-sample reading with one-tap calibration (a sheet of white paper in daylight) and light-source correction for 6 sources (sunlight, fluorescent, full-spectrum LED, grow LED, HPS, CMH).
• Get a 0-100 score with a clear traffic-light verdict (low / ok / enough) and one line of advice.
• DLI made simple: your light becomes a Daily Light Integral and is compared to what your species needs. Save readings to build a light history per plant and per spot, in lux / fc / DLI.
• Readings are a relative light indicator, calibrated to your device - not a lab-grade lux meter.

ALL-IN-ONE CARE FOR 391 SPECIES

• A built-in care database for 391 plants covers light, water, fertilizer, repotting, humidity, and ideal temperature, all in one place.
• Care reminders for all five: watering, feeding, repotting, humidity, and leaf care, tuned to your measured light and the season.
• No more juggling sticky notes and generic schedules. Each plant knows what it needs.

MAKE IT YOURS

• Give every pot a nickname, so two of the same species stay separate and personal.
• Keep a photo growth journal for each plant: add progress photos and notes, set a cover photo, and sort oldest-first to watch it grow.

YOUR DATA STAYS YOURS

• Works offline, on device, with no account and no sign-up.
• Back up and restore everything - plants, care history, and photos - to your own Google Drive or iCloud, for free. Your data is always yours to keep and move.
