Tarte introduction (Korean)
Product & design direction, Android development
My role during the course of this project was providing product & design direction, pitching the work to executives including the CEO, building up the team from scratch to an interdisciplinary team of designers and developers, and getting hands-on in design & development. Due to the absence of full time developers early on, I led the development work for the proof-of-concept and what became the skeleton for the Android product.
Problem space
It all started out with the following observation.
  1. Regardless of who you are, you have a set of things to do.
  2. People are getting busier & busier every day, and it becomes impossible to keep track of everything in your head.
  3. So people begin to track their tasks in to-do lists (or app) or memos. However, these are still "dumb" and are just a list of static strings.
So we began diving in deeper to understanding the key pillars in this problem space through research.
Out of the array of problems we've identified, the following stuck out to us more than others.
Out of the array of problems we've identified, the following stuck out to us more than others.
  • Being able to add & remind yourself about a to-do is just the beginning. Experiences around actually helping you get a to-do done have been missing.
  • Whether you keep a (long) single list or use a set of (shorter) lists, it's a lot of work organizing.
  • You may think of a to-do while in the context of another activity. It's a lot of hassle & depths to stop what you are doing, navigate to your to-do app, jot things down, and come back to what you were doing.
We took these problem areas and began working on creating the designs to transform these into new opportunities.
Product concept
We imagined what if there were a task-driven product that
  1. Intelligently keeps my list organized,
  2. Goes beyond a reminder & actually helps me complete each item,
  3. Makes it super easy to jot down a to-do from anywhere.
Tarte is a todo app that goes beyond reminder to help you get things done in the following ways.
Intent-driven intelligence
The intelligence in Tarte is built around the following core intents & actions. We chose these 9 based on relevant services NAVER has and what we’ve seen as most commonly used during internal beta testing.
Making a reservation, Purchasing a shopping item, Researching more information about a topic, Call, Text message, Sending money (such as Venmo-ing someone), Getting directions, Movies, and Books.
We’ve built the input experience in the following ways.
  • User can type in freely or input quickly using action-related shortcuts provided above. Based on what the user has put in, we analyzed what the intent through natural language processing and algorithm we’ve built. The order of these guided shortcuts were determined based on the frequency of intents used during internal beta testing.
  • As you are typing, autocomplete based on common input by other NAVER users will also show up.
  • From user’s input, Tarte checks see if there’s a reminder that may be inferred.

What you create gets added to the todo list. When you tap on a task and if there’s something Tarte can help you with, assistive information & actions will be populated in the task detail view.

For example, user creates a task to buying a swim tube for an upcoming trip to the beach. When user types in the todo, Tarte analyzes what it is through natural language understanding to determine its intent. When the todo is successfully mapped to one of the supported intents, Tarte surfaces relevant content such as a list of swim tubes that user can purchase.

Depending on the type of intent, the populated view will vary to provide the most relevant actions and information.

Smart List
If you are an avid todo user, it is easy to find your list piling up. It is takes time and effort to organize these todos into specific sub-lists. However, there is value and efficiency in being able to batch & tackle similar todos together.

In Tarte, users can create and manage their own lists. In addition, Tarte groups similar types of tasks into what we call Smart Lists based on their intents. These lists are created, updated, and removed automatically. Belief here was that, by grouping and allowing you to tackle similar tasks in a series (ex. Making a series of reservations) would lead to a more productive time spent.

When you think of something to do, isn't it quite tedious to stop what you are doing, open your todo app, write down your thought, and return to what you were previously doing? To shorten that process and make it easier for the users, we designed & built an overlay that user can launch from any app simply by long pressing the home button. Jot down a new task without jumping away from what you are doing.

The experience is similar to composer in-app. But in addition, if there’s assistive information, it is shown right as you are typing in the overlay. This was a feature on Android.

As you type in the todo, Tarte will also intelligently surface assistive actions on the fly.
Plan your day
Lastly, Tarte makes it easy to triage your tasks for today. It nudges you in the morning to Plan Your Day with todo without assigned due dates, and you can later view them from the app itself.

Product release
Android shipped on July 24, 2017, and iOS shipped on November 16, 2017.

We ran this product experimentation for over a year in Korea,  and ultimately graduated the product and fed the insights & learnings into bigger productivity products within the company for strategic reasons. Incubation Studio also wasn’t intended to grow into a business function, but to hand off and explore new opportunities after each experiment.
