Haha interactive is an app developer focused on everyday productivity and life-logging use cases. Its website lists products such as Hi Sticky, JustTrack, GoodTask, and My Wonderful Days. It is more of a collection of personal tools for the Apple ecosystem than developer-facing infrastructure or a SaaS platform.
Based on the site content, Hi Sticky focuses on plain-text notes and widgets; JustTrack is for tracking numbers and habits, including health-related metrics such as weight and steps; GoodTask is a task manager built on Apple Reminders and Calendars; and My Wonderful Days is for daily journaling. The products all provide App Store and Mac App Store links, indicating a focus on iOS/macOS. In terms of integrations, the only clearly stated one is GoodTask’s integration with Apple’s Reminders and Calendar systems, making it suitable for users deeply invested in Apple devices.
The terms state that the software, front-end and back-end code, UX/UI, source code, and related assets are the property of haha interactive or its suppliers, and prohibit reverse engineering, modification, publication, or the creation of derivative works. As such, there is no indication of open-source attributes, and it should generally be understood as closed-source commercial software. The site does not mention APIs, SDKs, self-hosting, plugin systems, or developer integrations, nor does it provide technical documentation or a help center. Its relevance as a “developer tool” is therefore limited.
The website does not list specific prices, only stating that paid subscriptions are available inside the macOS/iOS apps. Subscriptions are charged to the user’s iTunes Account upon purchase confirmation and renew automatically. Users must turn off auto-renewal at least 24 hours before the end of the current billing period. Pricing needs to be checked in the app menu, so price transparency is only average.
The strengths are that the products focus on high-frequency personal use cases and rely on Apple’s native ecosystem, which may keep the learning curve low. The downsides are the lack of information on cross-platform support, team collaboration, APIs, data export, and enterprise support; pricing also needs to be confirmed after installation. It is suitable for individual iPhone/Mac users who want to manage notes, tasks, habits, and journals, but not for development teams looking for integration, self-hosting, or automation capabilities.
The site does not provide information about access, payments, or localization for mainland China. Since distribution and subscriptions depend on the App Store/Mac App Store and Apple in-app purchases, actual availability depends on the user’s region and network environment. Alternatives include Apple Notes, Reminders, Things, Todoist, Notion, and Day One.
