Independent developer building mobile apps and web projects with AI. Focused on clean UX, sustainable monetization, and user privacy.
Jimper Studio is a one-person indie development studio. I design, build, and ship mobile applications and web experiences using modern AI-assisted workflows. Every product is crafted with attention to performance, accessibility, and user trust.
Current focus: language-learning tools with interactive mechanics and subscription-supported sustainability.
An interactive Chinese cloze-test trainer. Users tap missing characters to complete sentences, with stroke-order animation, spaced repetition, and progress tracking. Built with React Native and Expo.
Additional AI-powered apps and web experiments are in development. This page will be updated as they enter beta or launch.
My apps use transparent, user-friendly monetization strategies that respect player experience:
Users can access core features at no cost. Ads are shown via rewarded video and non-intrusive banners through certified networks.
An affordable annual subscription removes ads and unlocks premium features like unlimited practice and advanced analytics.
Selected projects may offer lifetime unlock options for users who prefer a single payment.
No third-party tracking beyond essential ad attribution. All payment processing follows PCI-compliant vendor standards.
For business inquiries, partnership proposals, or press, please reach out via email. Response time is typically within 48 hours.
Jimper Studio is committed to full regulatory compliance across all jurisdictions where its apps are distributed.
We collect only the minimum data necessary to operate the app and process payments. Personal data is never sold. For the full policy, see the Privacy Policy page linked in each app and on this site.
All payments, subscriptions, and in-app purchases are processed exclusively through third-party platforms (including but not limited to Google Play, Apple App Store, Paddle, and any other distribution channels we may use in the future). We do not process, store, or handle payment transactions directly.
Refund requests must be submitted through the platform where the original purchase was made, in accordance with that platform's refund policy. As an independent developer, we do not have the ability to issue refunds ourselves; however, we fully comply with the refund requirements and procedures of each respective platform.
