About this app

Yoi Bonsai is the all-in-one companion for serious and casual bonsai growers. Build a private record of every tree in your collection: photos through the seasons, repotting and pruning notes, watering reminders, and AI-assisted summaries that turn years of log entries into a clean, readable history.

Free to download. Track up to 10 trees, browse the Ichiba marketplace, and message sellers about trees you'd like to add to your collection — no subscription required.

Upgrade to Premium for unlimited trees, AI features, the full marketplace experience, and sharing tools you'll actually use.

WHAT YOU CAN DO

Track your trees
• Add a photo, a note, or both — every entry timestamps automatically
• Photos by season build a visual history you can scroll through
• Repotting log keeps the date you last touched the soil one tap away
• Cover photo, species, height, pot, age — the details that matter to you and a future buyer

Reminders that respect how bonsai actually works
• Recurring monthly reminders for the work you do every year (repot, fertilize, wire-off, defoliate)
• Single-tree or multi-tree reminders — fertilize the whole back bench in one tap
• Mark a reminder complete and it auto-creates a log entry on each tree, so your history stays in sync

AI-powered summaries (Premium)
• Generate a clean, readable summary of any tree's history from its log entries — perfect for sharing or remembering what you did three years ago

Ichiba marketplace
• Browse trees for sale from other growers
• Message sellers directly to ask questions before buying
• Premium subscribers can list their own trees, including AI-assisted listing copy
• Tree transfers move ownership cleanly with full history intact

Sharing and collaboration (Premium)
• Share trees with another grower — read-only or full edit access
• Transfer trees permanently when you sell, gift, or downsize
• Built for instructor / student workflows where both parties need to see and update the same trees

Privacy first
• Your trees, photos, and notes are yours alone unless you choose to share
• No ads, no tracking pixels, no selling your data — ever
• Sign out wipes the device; delete your account and we anonymize the record

PLANS

If a Premium subscription expires, your trees, photos, and reminders all stay. You'll have a 7-day grace period before the limits return; the first 10 trees you created remain editable, and the rest become read-only until you renew or trim back.

Cancel anytime through your Google Play subscriptions. Auto-renews unless cancelled.
