CaudexCare: Rare Plant Journal

Full English UI is now live — cultivation guide, daily tips, billing & Apple Sign-In all localized. For Pachypodium, Agave & 130+ rare species collectors.

Your Pachypodium gracilius is looking thin. You know water is coming — but when, exactly?

CaudexCare is built for collectors who take their plants seriously. Not an AI identifier. Not a social feed. A focused care log for the plants that are genuinely hard to keep alive.

130+ RARE SPECIES BUILT IN

Browse a hand-curated database of 130+ caudiciform and rare succulent species — Pachypodium, Agave, Haworthia, Euphorbia, Adenium, and more. Each entry includes watering frequency, temperature range, and seasonal care notes. Yes, Agave victoriae-reginae is in there. So is Haworthia truncata.

——

WATERING REMINDERS, TUNED TO THE SPECIES

Log a watering event and the app tracks the next due date based on that species' data — not a generic "water every 7 days" timer. Slow-cycle desert plants need their own rhythm.

——

WEATHER-ADAPTIVE CARE (Japan only — for now)

Weather-based watering advice is currently available in Japan only, using JMA (Japan Meteorological Agency) data. Rainy or cold in Japan? The app adjusts your watering suggestion automatically. Outside Japan, the weather card can be hidden in one tap — and every other feature works without restriction. Worldwide weather support via Apple WeatherKit is planned for a future update.

——

GROWING CHARACTER — 5 STAGES

Your accumulated waterings grow a botanical mascot: seed → sprout → plant → bloom → prestige star. Drawn in copper-plate botanical engraving style. It does not ask for your attention. It just quietly grows.

——

SHARE YOUR COLLECTION

Generate a 1080 × 1350 share card with copper-plate botanical art overlays — ready for Instagram or X in one tap. The aesthetic owes something to Curtis's Botanical Magazine, built for collectors who care about how things look as well as how they grow.

——

OBSERVATION NOTES & MONTHLY HISTORY

Log repotting, root conditions, and growth notes inline on each plant's page. See watering frequency by month to understand seasonal rhythms on slow-growing species.

——

PREMIUM — ¥480 / YEAR (APPROX. $3.99)

Cloud sync across devices is the only paid feature. The plant database, watering reminders, growing character, share cards, and observation notes are all free — permanently.
