From Idea to Launch: Developing a Seamless App for Quick Thoughts

I’ve always been a fan of Simplenote. Its minimalist design allows me to focus on writing without the distraction of formatting. Every time I open it, I can start typing right away, letting my thoughts flow onto the screen. This pure experience makes me feel at ease and allows me to truly appreciate the writing process itself.

However, as I began to record spontaneous ideas, I realized a new need. I wanted a more lightweight, more immediate way to capture thoughts—something that didn’t require a title or unnecessary steps, something as free and casual as posting a tweet on X. While Simplenote is already quite simple, it still felt a bit too "formal" for this need.

So, I started to think—could I create a tool that was built specifically for this kind of recording? It should be lightweight enough for users to start typing with one click, free of distractions; it should be flexible enough that there’s no need for titles or formatting; and it should be smooth enough that recording feels like a natural, effortless experience, not a task that requires extra thinking.

Driven by these thoughts, I developed this app. It started from my personal need, but I believe many others, like me, would also appreciate having such a simple and efficient tool for capturing ideas. I hope it allows every spark of inspiration, every sudden thought, to be captured in time without being forgotten because of cumbersome steps.

At first, my goal was very simple: create an app similar to Apple’s built-in Notes app—something simple for quick recording. The design didn’t have much thought behind it; I just wanted a place where I could easily jot down ideas. However, after using it for a while, I realized that while this simple design met the basic needs, it lacked that “light and breezy” feeling—too plain to bring me any real enjoyment.

I began tweaking the UI, trying different designs to find something more suitable for fast recording. I experimented with many different layouts, and eventually realized that a plain text box wasn’t enough. The real challenge became creating an interaction that was lightweight, convenient, and casual, not “formal” or too structured.

Eventually, I landed on a design that fit the “light” and “short-note” concept: a button at the bottom that, when clicked, pops up a simple input box. This design is quick, fluid, and reduces the number of steps users need to take, perfectly aligning with the minimalist goal.

To make this a reality, I spent a lot of time on the UI design. A beautiful, elegant interface is crucial because it enhances the user experience, making the process of recording an enjoyable one. I spent almost every day adjusting icons and refining details to provide users with the simplest and most comfortable interface possible.

In the end, I decided to place a capsule-shaped button at the bottom with a golden ratio, and incorporated gestures (like left swipe to open search and optimized opening of the label list). This design ultimately achieved the minimalist objective I was aiming for, and I am very happy with the results.

This is my first iOS app, and after two rejections, I finally succeeded in getting it approved. After four iterations, I believe the app has reached my basic goals, and I’m excited to share it with everyone. I will continue to improve it, and I hope it will provide a tool for capturing and recording inspiration for many others.
