About this startup

Asking US$1,500, negotiable. Developed by Nodulo Noroeste. Contact: Dukemediatesting@gmail.com.

Jump Nodule is an offline Android jump-rope app project with a distinctive pixel-art identity and Nodo, a kangaroo companion that jumps with a moving rope. It is a foundation for a developer, coach or fitness brand to continue developing and launch under its own branding.

Implemented features include experimental sensor-based jump counting, optional calibration, daily goals and streaks, session history, configurable intervals and rests, metronome and sound palettes, sourced routine suggestions, a custom challenge builder and three Advanced home-screen widget designs. The app supports Spanish, English, French, Japanese, Russian and Simplified Chinese, light/dark appearance, CSV export and local backup/restore. Its current functionality works offline without an account or hosted backend.

Current stage: 0.6.0-alpha, pre-launch and pre-revenue, not published on Google Play. Seventy-five distinct local automated Android tests have passed; these do not establish real-world sensor accuracy. Physical-device validation, native-language editorial review and production launch work remain pending. Advanced has an access boundary, but commercial billing is not integrated. No customers, downloads, operating profit or income history are claimed. This is a software-project acquisition, not an established revenue stream.

The sale includes the full Android source project, a private demo APK, transferable app assets with relevant third-party licenses, the product/business plan and build/test documentation. Existing sales-presentation material is also included. The seller's corporate website and Nodulo Noroeste company identity are excluded.

Promotional screens show example data. Source code, APK and business plan are not public downloads. Contact us to discuss a private evaluation and the proposed handover.

Revenue and profit displayed as $0 indicate an unmonetized pre-launch project; development expenditure is not included in those operating figures.
