You can use Bubble Clouds on your watch in either of two modes:

1. Together with any watch face in “App drawer mode”
2. Set as the watch face

…are the little color circles. It’s a common name for all the different things which can be managed and moved around. There are:

• app bubbles (probably the most obvious, apps on your watch appear as bubbles. You can organize them into clouds, favorites or archive at least, but you can also move them into folders or hide unused/unneeded ones)
• toggle bubbles (such as switches for bluetooth, sound muting and other on/off type switches)
• watch face complication bubbles (when Bubble Cloud is set as your watch face, you can add as many watch face complications as you possibly want, they are bubbles just like any other bubble, so you can also move them into any cloud, assign them to shortcuts etc)
• smart home control bubbles (which can directly send HTTP commands to various smart home lights and appliances – again, there is no limit on these, you can have as many multi-state smart home control bubbles as you want and move them to any cloud)
• Tasker bubbles (if you are into Tasker automation, Tasker tasks/routines can show up as bubbles on your watch, and you can trigger these automations on your phone by clicking on these Tasker bubbles. More over, Bubble Cloud’s Tasker plugin lets you update these appearance and location of these Tasker bubbles, which makes them very powerful automation tools – you can have a different set of controls depending on the time of day or location etc)
• phone app bubbles (which as the name suggests can start apps on your phone)
• folder bubbles (as described earlier. But as folders appear as bubbles themselves you can stack them inside each other, and assign them to shortcuts etc)
• theme bubbles (you can change the appearance of the Bubble Cloud watch face using so called 1-click themes. You can find a bunch of them here. Basically they are analog/digital/worded or dual watch faces, which can normally be activated from the 1-click themes menu of the app, but you can also save a 1-click theme as a bubble, so you can use that bubble to switch between a set of different watch faces literally with a single click. You can also activate these via Tasker)

…are the groups of these bubbles. Initially bubbles on your watch are split into two main clouds: the “favorites” cloud, which has your most important bubbles, and the archive cloud, which has everything else. If you add more and more bubbles to control your phone, smart home etc, you will also want to create new clouds, these are the folders. These folders then can be accessed via a hardware button press, from a watch face complication or even shown as a Wear OS tile.

When you use Bubble Cloud as your watch face, the favorite cloud is actually your watch face, it just has a clock bubble that shows the time, and depending on the cloud layout, it can resemble an analog or digital watch face, but basically it’s just a cloud of bubbles:

Or with different layouts you can make it look more like a traditional analog or digital watch face:

 

Or more advanced layouts:

Bubble Edit Screen

On the watch

• That’s where you can move bubbles into various clouds (favorite, archive or folders – even the Wear OS tile).
• And that’s the place where you can assign them to various types of shortcuts (hardware buttons, watch face taps, etc)

You can read more about the Bubble Edit screen here: Bubble Edit screen on the watch

Once you understand this simple basic concept, bubbles and clouds and how to manage them (simply by long pressing them) I think the system becomes clearer and much easier to navigate, and you start to feel the freedom this provides to accomplish anything, and most importantly to quickly rearrange things on the go!  For example, it is extremely easy to add just one extra bubble to your watch face, if you know you will need the calculator more in the next hour, you can long press the calculator bubble and temporarily add it to your watch face. The watch face smart auto layout will rearrange itself to make space for the new bubble and you can have it there as long as you need it!

E.g.

Bubble Cloud is one of the most versatile watch faces:

• with a hundred different analog and digital themes and infinite variability
  • See all the ready made themes here
  • See an example on how to combine theme components to create your own
  • See a complete explanation of creating your own themes
  • 1-tap to change between analog and digital watch face (more info)
• This watch face includes bubbles for all the apps installed on your watch
  • your favorites can be on the screen all the time (i.e. “favorites cloud”)
  • others you can move to the “archive cloud” (which you can quickly access by swiping horizontally)
  • yet others can even be organized into folders, just like on your phone
  • long press bubbles to move them between clouds (see post on Bubble Edit screen)
• In addition to apps, you can have other types of bubbles:
  • toggle bubbles to adjust wifi, bluetooth, sound volume etc (see post)
  • any number of watch face complications – you can have more complications than can fit on your watch face, since they can also be moved into the archive cloud and folders! (see more info)
  • Smart Home controls / Smart Light switches (more info)
  • automation bubbles to start Tasker tasks (more info)
  • even start apps on your phone using bubbles on your watch (more info)

Before starting to use Bubble Cloud as your watch face, please see this post:
Introduction to Watch Face mode

You don’t have to use the Bubble Cloud watch face. If you have a favorite watch face, you can use Bubble Cloud together with it as a replacement or addition to the app list provided by the system:

• The Bubble Cloud app launcher has more flexible layouts, which put more icons on the screen – less scrolling, quicker access
• You can organize your apps into folders, hide the ones you don’t need
  • long press bubbles to move them between clouds (see post on Bubble Edit screen)
• In addition to apps, you can have other types of bubbles:
  • toggle bubbles to adjust wifi, bluetooth, sound volume etc (see post)
  • Smart Home controls / Smart Light switches (more info)
  • automation bubbles to start Tasker tasks (more info)
  • even start apps on your phone using bubbles on your watch (more info)

Bubble Cloud shows your apps, watch face complications and other items as bubbles. Initially these bubbles can be organized into three groups (or “clouds”):

You can also create folders and even assign a folder to the Wear OS tile. There is also a Wear Contact Cloud to call or text a select number of people from your watch.

When Bubble Cloud is set as your watch face, the favorite cloud becomes the watch face.  It will have the clock bubble, and it can have a few other bubbles. The rest of the bubbles are accessible via horizontal swipe:

Move bubbles between archive and favorites:

Either way you use Bubble Cloud (watch face or app drawer or even if you don’t use either of them) you can still assign actions to various shortcuts:

• remap the long press of the main button (and even assign a second action to the double long press)
  (see more info)
• assign apps, Tasker tasks, Smart light toggles, folders etc to the single or double press of the other button(s) of your watch (see more info)

The app does a few more things, regardless of the main way you use it:

• Feature: Vitals timer for doctors and medical professionals (ambient mode with seconds hand)
• Automatic day/night brightness management (Dim your ambient watch face at the same time every day)
• Sticky open (Double tap an app bubble to open it, and also keep it on screen until it’s not needed any more)
• Touch lock – protect against accidental touches
• Wear Stand Up Alert (plugin)
• Notification icons on any watch face! (via complications) (plugin)

Before staring with the home screen widgets, I recommend reading the introductory post on widgets:

The app has a very comprehensive website with thousands of posts about the app:
