DS Soft について About DS Soft

At DS Soft, we develop apps based on the idea of ​​"it would be great to have this"—a concept born from our own musical experiences.
Even with standard tools like metronomes and tuners, we incorporate our own unique touches—such as clock-style indicators or polyrhythm functions—reflecting the features we personally wished existed.
We may sometimes venture into niche territory with features that are far from conventional. You might encounter functions like odd-meter conversion, undertone series, or N-tone equal temperament techniques, and wonder, "What are these actually used for?"
Nevertheless, we continue our development in the hope that even a single user might discover a new world of sound through our apps.

We are dedicated to addressing niche needs and solving daily inconveniences that mainstream apps often overlook.
While modern designs tend to hide advanced settings under the guise of "simplicity" or "auto-optimization," we avoid hardcoding parameters and instead leave them open for users to customize. We strive to balance intuitive ease-of-use for beginners with the freedom for advanced users to fully customize their experience.

We process all sensitive files, such as audio and video, entirely on your local device without ever uploading them to a remote server.
While processing speeds may vary depending on your device's performance, this approach completely eliminates the risk of external data leaks, ensuring your privacy is fully protected at all times.

Our tool-based apps prioritize the experience of "pure discovery" through the manipulation of parameters and logic, which may make them appear understated at first glance. This is a deliberate choice — one that conserves development resources, reduces device load, and allows users to perceive parameter changes without unnecessary distractions.
We hope that adjusting these settings inspires users to think, "What if I change this? Wouldn't it be more interesting or useful?" and sparks a cycle of creative ideas. Indeed, our own development process is built upon this very cycle of trial, error, and discovery.

Leveraging the agility of a small development team, we strive to turn user feedback and ideas into reality as quickly as possible.
The rise of generative AI has dramatically reduced the cost of experimenting with new ideas. At the same time, we believe that—at least for now—usability and the finer details of quality are aspects that can only be refined through repeated collaboration and iteration between humans and AI. We feel this is especially true for relatively niche applications like those developed by DS Soft.
At DS Soft, we actively use AI to accelerate the Build (Do) → Test (Check) cycle, allowing us to respond to user feedback quickly while maintaining a high standard of quality.
Many of the improvements we've delivered—including the addition of the Phase Vocoder feature and enhanced track separation accuracy in Pitch Tempo Changer, as well as the timer feature in Pink Noise Generator—were inspired directly by feedback from our users.

None of our apps display popups asking you to rate or review them. We believe these prompts disrupt the pure user experience (UX) and distort the fairness of app store ratings.
For instance, by targeting only highly active users (e.g., displaying a prompt only after five days of continuous use), marketing tactics can easily filter ratings and inflate scores, overshadowing the actual quality of the app.
Every review we receive comes from users who genuinely felt inspired to return to the app store on their own initiative to leave a rating or comment. We believe these voluntary voices are infinitely more valuable than prompts driven by popups, and they serve as our only true guide.
