What we do
From bespoke enterprise software to a published family of consumer mobile applications, Jingrui Yuetao partners with brands and individuals across more than 120 countries. Every engagement is anchored in the same belief: technology should disappear into the workflow, never the other way around.
Core capabilities
We organise our work into four interlocking practices. Most engagements draw on more than one. Together they let us ship products that are well designed, well engineered and well loved.
End-to-end design, build and operation of web, mobile and backend systems. We work in native Android (Kotlin, Jetpack), iOS (Swift), modern web stacks (TypeScript, React, Node) and cloud infrastructure (AWS, GCP, Aliyun).
From concept sketches to App Store and Google Play publication, we own the full product lifecycle: research, UX, UI, engineering, localisation, ASO, growth, and ongoing maintenance. Six live apps and counting.
GDPR, CCPA/CPRA, LGPD, PIPL and Google Play Data Safety form-filling. We help product teams ship compliant software with documented data flows, consent UX and DPIA templates.
Ad mediation (AdMob, Meta, Unity, AppLovin, Pangle, Vungle, InMobi, ironSource, Digital Turbine, Mintegral), subscription funnels, paywall experimentation, ASO and store-listing design.
Our Google Play family
In the application research and development space, we are deeply invested in building a localised tool ecosystem. On Google Play we have published multiple beautifully designed, technically rigorous utility applications. Our matrix spans outdoor offline route parsers, collection asset filing systems, writing inspiration engines, sports load calculators, household bill scanners and recurring habit trackers.
We adhere to a "data stays local" engineering philosophy: under the premise of safeguarding absolute user privacy, we build a freely controllable, exploratory and ceremonial offline digital utility suite for outdoor adventures, collecting, fitness, creative composite life scenarios.
An offline-first outdoor route parser. Imports GPX, KML and TCX files, lets you slice, reverse, merge and waypoint-edit any track, then exports back to your favourite format. Perfect for the trail, the road, or the backcountry.
A collection asset filing system for serious hobbyists. Catalogue watches, sneakers, vinyl, coins, art, books and more with rich metadata, photo grids, condition tracking and CSV/PDF export. No account required.
A text-based creative inspiration engine. Capture fleeting thoughts, snippets of dialogue, evocative words, and visual references. Organise by mood, project or colour, and let serendipity surface what you forgot you wrote.
A sports training load calculator using TRIMP, ACWR and acute-to-chronic ratios. Works offline, logs sessions in seconds, and gives you a clean weekly view of fatigue and readiness so you train smarter, not harder.
A household bill local scanner. Snap a receipt, invoice or warranty card; on-device OCR captures merchant, amount, date and category. Search, tag, and export to CSV without sending a single pixel to the cloud.
A periodic habit tracker that values consistency over streaks. Daily, weekly or custom cadences, gentle reminders, and a beautifully designed year-view that rewards small, repeated effort over noisy perfectionism.
Engagement model
Whether we are co-creating a brand new app or hardening an existing codebase, every Jingrui Yuetao engagement follows the same calm, well-documented rhythm. You will always know what is happening this week, what is shipping next, and what is at risk.
