Where ideas hatch into reality.
SPARKEGG STUDIO uses AI to bridge the distance between what we imagine and what people can actually use.
What we make
From everyday information and health records to memories preserved in 3D and custom support for small businesses, we build products and services around the reality of the people using them.
An iPhone app that brings mobile data, AI service usage, connected-device battery levels, schedules, notes, habits, weather, and more into one widget—so the information you need is visible at a glance and managed in one place.
All main features require paid access. Eligible users can try them free for 14 days.
We plan to connect our own apps and grow WidgetMix into a dashboard for health records, household budgets, and more.
An app branching from Lifestyle Health Diary, focused on keeping blood glucose readings, measurement timing, and everyday notes easy to record and review.
We plan to make selected records viewable through WidgetMix.
Built on the ideas behind Lifestyle Health Diary, this app aims to make blood pressure logging easier to maintain, with morning and evening readings and notes that help you review changes over time.
Integration with WidgetMix is planned, alongside the blood glucose app.
A smartphone-first accounting app in development for sole proprietors and side-business owners in Japan, with no bookkeeping expertise required. Photograph receipts, import statements, and review classification suggestions—the aim is to turn simple daily steps into preparation for blue- or white-return tax filing.
We aim to make business-use allocations and month-end checks easy to understand. Development starts with iPhone, with bookkeeping and tax-preparation summaries planned in stages.
We are exploring an app that uses AI to estimate dishes and approximate calories from meal photos. You would be able to correct portions and estimates, then review meals alongside changes in weight.
Estimates would be a guide, not precise measurements. Future WidgetMix integration would help you check selected meal and weight records.
A concept for bringing spending, monthly budgets, subscription renewals, and upcoming credit card payments together. The aim is to make fixed costs and remaining budgets easier to understand.
We envisage user-entered records first, with future WidgetMix integration for remaining budgets and upcoming payments.
3D Master is a memory app in development for capturing the people, family members, pets, and keepsakes that matter to you with an iPhone, preserving them as 3D models or 2D cutouts, and creating new photos with them in AR. We are currently developing and testing on physical devices the experience for saving materials, placing and adjusting 2D and 3D content in AR, and taking photos.
AI generation that preserves a person’s identity is still in research, with quality and privacy as our highest priorities. No production cloud AI is currently integrated into the app.
A service that replaces workflows managed through paper, spreadsheets, LINE messages, and manual entry with small internal apps for phones and PCs. Custom apps can be purchased outright or provided through a low-cost subscription with a separate development fee.
To keep monthly pricing affordable, subscription plans do not include extensive ongoing support or unlimited revisions. We also create budget-friendly static websites. Pricing and the scope of each project are agreed through consultation.
Apps in development or at concept stage, and integrations with our own apps, are not currently available. Names, features, and release timing may change. Health apps are intended to support personal records, not to diagnose conditions or make treatment decisions.
Why SPARKEGG STUDIO
An idea in someone’s mind cannot change reality on its own. Technology, knowledge, time, and cost can all stand between what we imagine and what we are able to make real.
SPARKEGG STUDIO began with the realization that dialogue with AI can help us cross that distance. It can clarify thoughts that are not yet fully formed, help us choose the right technology, and support a process of building, testing, and refining until an idea becomes something that works in the real world. We believe AI is more than a tool for working faster: it expands how far human thought can reach into reality.
At the same time, being able to make something does not mean it is ready to be placed in someone’s hands.
Our goal is not to showcase technology for its own sake. We turn everyday frustrations, memories worth preserving, and ideas that have not yet found their form into products that are useful in real life and sustainable to use over time.
What people enter should not disappear. They should know when something has been saved, understand what to do next, and be able to recover when something goes wrong. They should also be able to keep using the product with confidence after it is complete.
Because we believe in the potential of AI, we do not exaggerate what it can do. We examine quality, privacy, cost, and operation before a product reaches people. We bring thought closer to reality—and take responsibility for the reality we create. That is how SPARKEGG STUDIO builds.
Even an idea that is not yet fully formed can contain the seed of real change. Through dialogue with AI, we uncover what is truly needed and shape it into something that can be built.
We do not begin by choosing features or technology. We first understand who will use the product, where they will use it, what is getting in their way, and what they need to do next.
From input and review to saving, output, and recovery, we design a flow that does not leave people stuck. Results and next steps are communicated in human terms.
Input retention, confirmation, backups, recovery, and protection against mistakes all matter. We design not only to prevent failure, but to help people regain their footing when something goes wrong.
A product includes real devices and environments, updates, help, and maintenance. We do not stop at a working prototype; we aim for something people can continue to use in everyday life.
We do not confuse “we generated it” with “it achieved its purpose.” We verify quality and safety, and we do not claim that something is possible before it truly is.
