Do not mistake a smartwatch for a small smartphone. Which content belongs on your wrist — and which does not? How is good user experience on a Smartwatch defined and how do you achieve a great user experience on a smartwatch? We worked on different projects for Apple Watch and Android Smartwatch for the past months. From these projects and from personal use of the devices we derived seven guidelines for a greater App experience on Smartwatches.

7. “Only content which i’m able to consume in less
than five seconds belongs on a watch.“
THORSTEN JONAS, CREATION CELLULAR
1. Make it glanceable

8. • Limit any interactions to five seconds.
• Use icons in combination with precise
wording.
• Use actual sized paper mockups of your
app to verify its content’s readability.
1. Make it glanceable
Smartwatches are often used by taking a glance on your wrist.
Consequently, information need to be designed for these short
moments of interaction.

9. “Nobody wants to be interrupted by an incoming
email notification while taking a nap.
Nevertheless, your alarm should set off.“

2. Context is king

10. 2. Context is king
Pushing relevant information at the right point of time is key to a
great smartwatch app. However, important content in an inadequate
situation can get lost.
10
• Reflect which situations your app can
enrich or simplify.
• Use all of the new available sensors to
determine the user’s context.
• Benefit from the context and use it as a
filter for your notifications.
Best practice:
GMail

11. “Watches are worn all day. Therefore, push
notifications can’t be ignored. The only
alternative is deleting the App.“
JÖRN SIEDENTOPP, CREATION CELLULAR
3. Respect the privacy

12. 3. Respect the privacy
A smartwatch is a very present device. As it is worn all day, it creates
a physical and emotional bonding with the wearer.
12
• Respect the wearer’s privacy and inform
him only in suitable situations by using
sound and vibrations.
• Less is more: Be even more sensible using
push notifications than on a smartphone
app.
Best practice:
Android Wear

13. 4. Reduce your phone usage
“Apps showing information directly instead of
teasers are the most useful.“
GUNNAR HAMM, CREATION CELLULAR

4. Reduce your phone usage
Often using a smartphone requires effort, such as getting it out of
your pocket. For example answering messages or paying with your
Apple Pay account during shopping.
• Offer a simple reaction using reply
suggestions.
• Let the user react to notifications: Read
later, show on phone, delete…
• Show enough information, so that the
user can decide if it’s worth checking his
phone.

“Typing on a smartphone is hard enough — on a
smartwatch it is overstraining.“
GÜNTHER LAMPRECHT, DEVELOPMENT CELLULAR
5. Try to avoid input

5. Try to avoid input
First of all, the smartwatch is an extended display of the
smartphone. The size of a smartwatch isn’t designed for more than
one gesture (swipe, tap).
• Input should be optional.
• Replace textfields by offering templates
and quick responses.
• If a longer text is required, voice input is
the only choice.
• Switch to the smartphone app for longer
interaction flows.
Best practice:

17. 6. Less is more
“The temptation to get as many features and
information on the watch as possible, is
immense.“
TATIANA RYBNIKOVA, DEVELOPMENT CELLULAR

6. Less is more
On a computer screen, the rather small smartwatch displays appear
much bigger than their actual size. This can lead to a wrong
evaluation resulting in poor designs.
• More functions mean longer interactions –
the smartphone got you covered for that.
• Focus on one single usecase and cover it.
• Start early testing on paper mockups.

19. 7. Extend the smartphone App
“Use the strengths of the smartwatch, to benefit
from it. If you develop for Apple Watch: Focus
on glances and notifications!“
SVEN JANSEN, DEVELOPMENT CELLULAR

7. Extend the smartphone App
Use the context to get specific information at a glance. For example:
“How much time is left till boarding?“ or “How long does it take to get
to the gate?“. Permanently wearing your smartwatch enables you to
get more and accurate data, that can extend your smartphone app.
• Think of useful extensions for the
smartphone app.
• Enrich the smartphone App using the new
accurate data.
• Use the context as a strength of the
smartwatch.

21. Naturally this leads to one simple rule:
Never just copy the range and
functions of a smartphone App.
