What It Is

宝石のtodoリスト is an iOS task management app by Jumpei Naka. It positions itself as “美しいタスク管理” — beautiful task management — using a gemstone theme to make daily ToDos more visually appealing. Based on the product page and terms, it is not an enterprise collaboration or project management tool, but a lightweight personal to-do list app.

Core Features and Product Capabilities

The app covers the basic ToDo workflow: creating, editing, and deleting tasks, managing completion status, and archiving completed items. It also supports due dates/times and notification reminders. Its main differentiator is “宝石设计によるタスクの装飾”: users can decorate tasks with gemstone-style designs and view a gemstone list. Premium features include unlocking all gemstone designs and iCloud backup. In terms of third-party integrations, the available text only mentions Apple ID, App Store, and iCloud. There is no evidence of integrations with external systems such as Todoist, calendar apps, or Slack, nor any information about APIs, Webhooks, or developer support.

Pricing and Trial

The business model is free basic usage plus a paid premium tier. The premium version, “宝石のtodoリスト プレミアム,” offers monthly subscription, annual subscription, and a one-time purchase option. After purchasing the lifetime version, users can permanently access the same premium features as subscribers. Subscriptions may include a free trial period; if not canceled before the trial ends, they automatically convert to paid subscriptions. Specific prices were not disclosed in the captured text. Payment, renewal, cancellation, and refunds are all handled through the Apple ID / App Store system.

Pros and Cons

Its strengths are clear positioning and a distinctive visual theme, making it suitable for individual users who care about aesthetics and simple reminders. The basic task features are complete, and iCloud backup is available as an option. The drawbacks are also clear: only iOS support is explicitly stated, with no mention of Web, Android, or desktop clients. There is no information about team collaboration, permission controls, enterprise administration, audit features, or compliance certifications. The terms also state that data preservation is not guaranteed, so users need to back up important data themselves.

Who It’s For and Access from China

It is better suited to iPhone users who want a personal daily checklist, reminders, and lightweight task archiving. It is not suitable for enterprise teams, complex project management, or scenarios requiring cross-platform synchronization. Access from mainland China cannot be determined from the text alone. If obtained through the App Store, payment and subscriptions will depend on the user’s Apple account region and available payment methods. Alternatives include Apple Reminders, 滴答清单, Todoist, Microsoft To Do, and Things.
