10 Lessons We Learned Designing Todoist for Apple Watch

todoist for apple watch

When Apple released its Apple Watch, we knew that it was going to be an entirely new and exciting platform to adapt our app to. As a device that is literally strapped to our bodies, the Apple Watch allows us to have constant access to content and information.

But with these exciting possibilities came new challenges designing for a much smaller screen with limited interactions. We had to start from square one to completely rethink the design and interactions of our app and create the best user experience possible. While coming up with solutions, we made sure to keep the core purpose of the watch in mind: brief, but frequent and important actions on the wrist.

“Apple Watch Guidelines foundations:

  • Lightweight interactions
  • Holistic Design
  • Personal communication”

At first, testing our app was only possible on the simulator Apple provided to developers. While the simulator allowed us to experiment with some preliminary designs, we knew we needed to use the actual device to design the best user experience possible.

We needed to feel the frustration of holding up our arms 15 seconds longer than necessary because a key feature was buried. We needed to figure out through daily use what information and actions are essential and what are just nice to have. And we needed to experience what does and does not make information “glanceable” on a wrist.

We wanted to use this post to show you what we learned by actually testing our app on the Apple Watch and the specific ways we redesigned our initial concept as a result.

Lesson #1: The Simulator can’t replace real testing.

While the simulator was a great starting point, there are some key aspects of the watch it just couldn’t recreate.

First, just like with a smartphone, we are accustomed to using such a device with one or two hands. Interacting with it on a computer screen creates an entirely different feel and flow to the app that left us blind to key aspects of the user experience.

Second, the watch is worn on your wrist, and it requires you to raise your arm to actively interact with it or to lift your wrist to access the information. If you fiddle around with it for too long, though, your arm gets tired fast. So we thought quick interactions – the less the better – were key to offer the best user experience on this wearable device.

Finally, the watch itself has unique ways to interact with it that are very user friendly: the digital crown, force touch and an entirely new home screen that was built specifically for the watch’s interface. After using these features on the actually watch, we were better able to imagine the possibilities and incorporate them into the app’s design in seamless ways.

Lesson #2: Apple Watches are not mini-iPhones. Design accordingly.

In order to adapt Todoist to Apple Watch, we had to ask ourselves: what is the core purpose of a wearable device? How can these foundations be applied to Todoist for Apple Watch? Besides the aesthetics, which functionality should we incorporate into the watch and how can we make Todoist as useful as possible for the user’s productivity?
These questions led us to the conclusion that it would be best not to directly port the iPhone app UI on the watch, but to rediscover the prime features of the app. We had to get rid of everything that was too complex to interact with, so that the watch app would only display the information that would be important today and in that very moment.

Before deciding on an iteration, we always asked ourselves: is this easy and simple enough? If it turned out that the app wasn’t there yet, we iterated the process and relied on our assumptions, interpretations and experience until we believed it was right.

Compared to other platforms, the Apple Watch has unique qualities. Our goal was to find those and adapt them to fit Todoist.

Lesson #3: The glance view has to be completely “glanceable”.

A glance is a focused interface that you use to display your app’s most important information.” (developer.apple.com)

We redesigned the glance view to make the most important information more accessible.

One of the screens that is unique to the Apple Watch is the glance view. It’s a screen the user can access when swiping up on the watch face and is meant to display only the most important information quickly. Todoist’s glance lets you see the number of tasks you have left as well as your next task.

We had a previous glance design that worked more or less, but using it on the actual watch showed that there is still room to make this more important information even easier to view. When it comes to the glance view milliseconds matter.

The new design of the glance now shows the number of tasks left much more prominently, and our app icon at the top is very subtle to have a visual context as well.

Lesson #4: Nailing the Main View is critical.

After the glance, the Main View is the most important view in an Apple Watch app. It’s the first view you see when entering an app. After using our watches, we realized that if an interaction lasts beyond a few taps you’re likely going to reach for your phone. You just can’t hold your arm up for that long. The Main View needed to provide easy access to the most important information and actions fast.

In our first attempt, every item was given the same importance. Since the app is used very briefly in the watch, we knew we had to set hierarchies. We experimented a little bit, and put the “Add Task” button at the top. However, this didn’t feel quite right.

The primary action in the app wasn’t adding tasks, but seeing the information – the tasks the user has left today. So we restructured the layout and gave the “Today” button more importance. Now it is slightly bigger than the others, and the number of tasks is highlighted to make it more easily accessible. The hue of the number is eye-catching and separates itself from all the other elements, which is great for a quick glance on the watch.

At the top, the users can see the account they logged in with and their Karma points. The inbox, projects, labels (premium) and filters are now located underneath.

We redesigned the Todoist Main View to make sure the most important information was readily accessible.

Lesson #5: Force Touch is powerful. Use wisely.

One of the most powerful, unique features of the Apple Watch is Force Touch.  Force Touch simply refers to firmly pressing on the screen. This action opens up a new menu depending on what screen you are in. After actually experiencing this feature, we realized that we could use it had huge potential for adding efficient functionality while saving screen space.

We decided to implement Force Touch in our app to enable the user to add a task, no matter where they are within the app. This gives users a simple, fast way to get a task out of their head and onto their to-do list without wasting valuable screen space.

Using Force Touch allows you to quickly add a task no matter what view you’re in.

Lesson #6: Compromises are unavoidable. Prioritize ruthlessly.

We quickly realized that the small screen size and limited interaction time meant that we would need to make hard decisions about which information and features should be prioritized.

Initially, we only showed a simple task list. If you wanted to interact with a task you had to tap on it to show any actions. We discussed this several times and tried to decide what is more important. Was it showing the task’s content or was it being able to quickly complete a task, which meant sacrificing the task’s information. We figured that taking the extra step to complete every task would be frustrating. For example, a user who wants to use Todoist while grocery shopping is going to want to quickly check items off the list.

We decided to go with the option that would enable the user to complete a task more quickly. We added a checkbox next to the task. Users can still tap the task to open the detailed view and see more options like scheduling.

We decided being able to quickly complete tasks from the task list was worth the valuable screen space.

Lesson #7: Important actions must to stay above the scroll.

One of the other unique feature of the watch is scroll using the digital crown.  It’s an awesome innovation that expands the amount of information users can access.  However, we quickly realized that scrolling also slows down interaction.

When testing out our original task view concept, we found that placing buttons at the bottom was extremely inconvenient. For longer tasks, the primary actions were hidden and the user would have to scroll, which would not have been very beneficial for the user experience. We decided to put the primary actions at the top to make them readily accessible. Users already know them from our mobile apps: Complete and Schedule. The date is slightly smaller, which supports the visual hierarchy of all the elements.

We redesigned the Task View to make sure the important actions stayed above the scroll.

Lesson #8: Use of color & icons purposefully.

For the Apple Watch app, we wanted to reflect the look and feel of Todoist mobile apps and to keep its brand color and iconography. Not an easy task on a 38mm watch face.

Our brand color is spread very subtly throughout the app and its icons, which were reworked specifically for the watch to ensure visibility as well as readability on the small screen.  We also reused familiar symbols like the scheduling icons and redefined the stroke’s thickness to make sure they work well on the black background and that they have enough contrast.

We adapted the scheduling icons from the iOS app for the watch to maintain the Todoist look and feel users are familiar with.

Lesson #9: Subtle animations, used sparingly, make for a delightful experience.

If done right, animations can enrich the user experience and the understanding of interactions. But as fun as they are to come up with, too many animations make for a slow and confusing app.  This is true for other platforms of course, but it becomes even more important on the Apple Watch where fast, intuitive interactions are essential.

We decided to use animations very carefully and ended up having two customized ones. The first one is the interaction to complete a task. When tapping the checkbox next to the task, the box is filled in, the tick appears and the task gets greyed out. This gives the user a visually cue that they’ve accomplished what they set out to do, allowing them to get out of the app more quickly. The second animation is the empty today view, a extremely important view.  where we used the checkmark design that we already had on iOS.

We used two subtle custom animations to make the app more intuitive and delightful to use.

Lesson #10: Some of the things we want to do just aren’t possible…yet.

Of course, the Apple Watch still has limitations we had to work around. Some of those we had to deal with were static images in the glance view, or that there are no swiping gestures and only tap interactions. The fact that current 3rd-party apps can only be extension of the iPhone means the performance isn’t nearly as fast as we’d like to make it.

However, Apple will soon be opening up exciting new possibilities for 3rd-party apps. The upcoming release of their new developer toolkit for the watch will make native apps possible. This will mean a much faster app that can take full advantage of the Apple Watch’s unique features like the taptic engine and complications, the small bits of information you can display right on the watch face.

As excited as we are about our first version of Todoist for Apple Watch, we can’t wait to keep innovating in the new space of wearable productivity. We’ll continue to look for the unique ways we can design and adapt our watch app to help users get their important tasks done with less time and effort. Stay tuned!
