It also boasts a range of useful features, such as category organization, notifications, and subtask functionality. InstantToDo aims to boost motivation for completing tasks by letting you set your favorite colors or images as backgrounds. Set a cherished family photo or your favorite celebrity as the background image, and watch your motivation skyrocket just to see it! Customize your ToDo app to make it one-of-a-kind in the world.

With the theme of “colorful and true to yourself,” we significantly updated this app, which was originally centered around the concept of photo-based to-dos. In the past, we tried using several to-do apps, but somehow, we always ended up not using them after a while. We wondered, “Why?” The reason was simple: managing tasks with to-do apps wasn’t fun. Opening the app felt lifeless, and the ever-growing list of tasks felt overwhelming and frustrating. It might be understandable that to-do apps, which primarily evolved as business tools from pen and paper, aren’t fun. However, we thought there could be a to-do app that excites you when you open it, one that you can’t help but look at even when there’s nothing new, and that just by looking at it, your heart leaps with joy. Like creating your own unique notebook with multiple colored pens when you were a student, we wanted InstantToDo to be that kind of self-satisfying, yet inviting app. A one-of-a-kind, colorful, and personalized notebook in the digital world. InstantToDo aimed to make completing tasks enjoyable and creating tasks fun. We believed that even when looking at a long list of accumulated tasks in the app, seeing them surrounded by your favorite colors and things would help boost your motivation. We envisioned InstantToDo as an app that not only keeps you organized but also brings joy and excitement to your daily life. By customizing the app to reflect your preferences, you’ll be inspired to complete your tasks and stay engaged with the app. In a world where most to-do apps are purely utilitarian, InstantToDo stands out by offering a personalized and vibrant experience. We wanted to make managing tasks not just about getting things done but also about self-expression and enjoying the process. Ultimately, our goal with InstantToDo was to create a to-do app that’s a pleasure to use and encourages users to stay motivated and connected to their goals in a fun, colorful way. By giving you the tools to make your task management experience truly your own, we hope that InstantToDo becomes an essential part of your daily routine and helps you achieve your goals with a smile on your face. ■about Privacy https://yukio.site/privacy-policy/ ■terms of service https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
