「OneThing: Focus! One thing at a time!」

「OneThing's Birth」
The fast pace of life gives me a headache.

The city where I live is well developed and gives me a decent job. The sun is shining every morning when I get up. After finishing my outfit and taking a taxi to the company, I started my day's work.

The first thing is to list the tasks for the day.

I seem to have become an expert in task management, but I still have a headache. After sorting out the task list, I am slightly obsessive and anxious, and I will feel sad and uneasy.

I need to understand the priority and relationship of the tasks, so that I can be more "assured"; or uphold a principle, "Focus! One thing at a time!".

By the way, this is how OneThing was born!

「How OneThing Works」
First of all, you need to determine, do you really have many tasks every day? OneThing is obviously a remedy for this kind of people.

Every day at 9 AM (if you notifications enabled), OneThing will gently remind you to list the tasks you need to complete that day. Reviewed your task list, pick out what you need to do right away, and set it as "Top Thing".

You should spend all your attention on the "Top Thing" to ensure that the most important task can be completed. When you finish the "Top Thing", OneThing will automatically set the "Next Thing" as "Top Thing", and of course you can set the "Next Thing" yourself.

In this way, you can complete all your task lists in order of priority and say goodbye to anxiety.

「OneThing Design」
I understand the importance of mood to state, so I try my best to make OneThing simple and practical. I believe that even a novice can quickly understand the essentials of OneThing, "Focus! One thing at a time!".

Quickly mark Done Things, adjust “Top Thing", humanized interaction and elegant animation, bring you a smooth feeling.

OneThing also includes thoughtful customization options, such as notification sounds, dark mode, and iCloud synchronization, which will definitely make you happier.

I hope that OneThing will become a kind of care and will give you more pleasure.

So if you have any good ideas, please don't be stingy, any good ideas! If you feel moved by OneThing, I hope to get your praise and share it with your friends~

Purchases will not restore.

The app was great until the IAP stopped working and won’t restore.

I’ve waited since October and haven’t heard back from the developer. I’ve lost the money I’ve spent until they can fix this.
