Yoi Bonsai is the all-in-one companion for serious and casual bonsai enthusiast. 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 with free version, browse the Ichiba marketplace, and message sellers about trees you'd like to add to your collection. 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 Free • 10 trees • Photos, logs, reminders • Browse Ichiba and message sellers • Buy trees from other growers Premium (monthly or annual) • Unlimited trees • AI tree summaries and listing copy • List trees for sale on Ichiba • Share and transfer trees with other growers • Direct messaging beyond the marketplace If a Premium subscription expires, your trees, photos, and reminders all stay.

WHO BUILDS THIS Yoi Bonsai is built and maintained by Lonnie Bowling — a working bonsai enthusiast. The project is run as a service to the bonsai community, not as a profit-maximizing business: the goal is the best possible platform, a reasonable subscription to develop and maintain it, and contribution to the advancement of the hobby and the art. The structural choices that follow are deliberate: • Ichiba charges zero fees. Sellers keep 100% of the sale. • Subscription fee held or lowered as the goal — never raised just to chase profit. • No ads. No tracking pixels. No selling your data — ever. • One-tap export of every tree, log entry, and reminder, plus bulk photos at original quality. • Real questions reach a real person. 3–5 business days, often faster. • If the app is ever discontinued, you get 90 days notice and a final export. This is built to be good for the long-haul enthusiast, not optimized for the new install. Cancel anytime through your App Store subscriptions. Auto-renews unless cancelled. ——— Terms of Use (EULA): https://yoibonsai.com/terms Privacy Policy: https://yoibonsai.com/privacy ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Premium Annual | $49.99 | per year | | Premium Monthly | $4.99 | per month | ## Version history (last 3 releases) ### 1.0.93 — 2026-07-16 • Download your tree photos — from a tree's ⋮ menu, choose which photos and where to save them, and they're saved at full resolution with their original dates. • New General Tasks strip at the top of the Trees screen shows reminders that aren't tied to a specific tree and are due soon — expand it to check them off or edit them in place. • Press and hold any photo in a tree's gallery or log to set it as the cover or delete it. • Reminders now turn red only once a task is actually overdue. • Fixed a save error when editing a tree that had no height entered. ### 1.0.90 — 2026-06-23 • Faster photo loading throughout the app — previews are pre-generated and cached, and new photos are optimized on upload, so there’s no more first-view lag on existing trees. • Smoother full-screen photos: pinch and pan together in one motion. • Improved the flow of navigating in the app by correcting and refining several UI and nav elements and behaviors. • You can add up to 50 photos at once, previously was 10. • New opt-out anonymous diagnostics to help us fix slowdowns — turn it off anytime in Settings → Anonymous diagnostics. ### 1.0.89 — 2026-05-30 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
