What We Support

Mobile App Development

We build iOS and Android apps for on-site business work, from requirements through development, store release or in-house distribution, and maintenance after release. We also connect them to your existing Windows systems and devices.

Does This Sound Familiar?

You want to move on-site records kept on paper or in Excel to smartphones or tablets

You want to view or enter data in your existing Windows system from outside the office or on site

You want an app that uses the camera, QR codes, or Bluetooth devices

You cannot decide whether to build for iOS or Android, or whether you need both

An app you built earlier stopped working after an OS update

You cannot reach the company that developed your app and are looking for someone to take over maintenance

What matters most in a business app is not how the screens look but that it keeps working on site without stopping. We design from the conditions of the place where it is used: weak signal, operation while wearing gloves, data that does not match the existing system, and so on.

What We Offer

New Business Mobile App Development

We build iOS and Android apps used on site, such as inspection, receiving checks, record keeping, and customer support, from requirements clarification through design and development.

Integration with Existing Systems and Devices

We connect mobile apps to your existing Windows apps, internal servers, cloud services, Bluetooth devices, and more. We can also modify the Windows side as part of the same work.

Store Release and In-House Distribution Support

We support release on the App Store / Google Play, test distribution via TestFlight and similar tools, and preparation for in-house distribution.

Modification and Maintenance of Existing Apps

We take over maintenance of released apps, including keeping up with OS updates, bug investigation, and feature additions.

Supported Technologies

iOS: Swift / SwiftUI
Android: Kotlin
Cross-platform: .NET MAUI and others
Camera and QR code scanning, communication with Bluetooth devices
Data integration with Windows apps, internal servers, and the cloud

Whether to build natively or cross-platform is chosen based on the features you need, the kinds of devices, and your in-house maintenance setup. We do not assume either one from the start.

How KomuraSoft Works with You

Our representative, Go Komura, has developed and investigated defects in device control, communication, and long-running systems. In mobile apps as well, we put weight on designing for continuous operation, such as how the app behaves when the connection drops or a device responds slowly.

Because Windows software development is our core business, in projects that connect an existing Windows system to a mobile app we can design and modify both sides together.

How We Proceed

Requirements Clarification We hear who will use the app, where, and for what, and sort out the features needed, the target OSes, and the systems and devices to integrate.

Approach Comparison and Estimate We compare native and cross-platform approaches, distribution methods, and maintenance setups, then fix the scope and provide an estimate.

Development and Test Distribution We hand over builds you can try on real devices early, and finish the app while reflecting the results of using it on site.

Release and Maintenance We handle store release or in-house distribution, and continue to support OS updates and modifications after release.

Contact Us

Start by telling us what the app is for

It is fine if you are only at the stage of "we want to move paper records to smartphones" or "we want to use our current Windows system on site." We will hear who uses it, where, and how your work flows today, and sort out what kind of app is likely to be most effective.

Frequently Asked Questions

Can you support both iOS and Android?

Yes. We support both. Together with you, we decide whether native development with SwiftUI / Kotlin or cross-platform development with .NET MAUI or similar fits better, based on the features you need, your maintenance setup, and your budget.

Can you build apps used only inside our company?

Yes. We also build in-house apps that are not published to the public stores. We choose the distribution method after checking how many devices you use and how they are managed (for example, whether you use MDM).

Can the app exchange data with our existing Windows system?

Yes. Windows software development is our core business, so we can also modify your existing Windows apps or internal servers as part of the same project. You do not need to outsource the mobile side and the Windows side separately.

Can you handle store review and release work?

Yes. We support everything from preparing the information needed for review to test distribution and release. However, review results are decided by Apple and Google, so we cannot guarantee that an app will be published.

How much does it cost?

It varies widely with the number of screens, the target OSes, and the systems and devices to integrate, so we provide an estimate after hearing your requirements. Start by telling us what the app is for, and who will use it where.
