Creately vs FluidUI

The templates are well thought-out and actually helps you get started. Not like many other sites where the details are already filled in.

Consist with an example diagram which we can use to draw the diagram.
Most required diagrams are available.

Does not require flash.

Easy to use drag and drop interface and a contextual toolbar that shows you all the important actions when you select an object. The automatic creation and connecting of next object alone saves tons of time.

You can invite anyone by their email addresses to collaborate with your diagram. You can see others' changes to the diagram real time with the Creately Online and Desktop app.

You can't edit diagram using the apps but provides a nice clean interface to view, share and comment on them.

Creately supports SVG (Scalar Vector Graphics) import and export to make your diagrams more attractive. It allows you to re-size your diagram as much as you want without getting it messed up.

The learning curve is relatively low compared to other software that supports animations/transitions. Both building the wireframes and designing the interactions is all drop and drag.

Work with your team on a design. Connect on live video calls and chat or add comments.

You can simulate all the typical iOS gestures such as tap, double tap, swipe & long hold. These gestures then can trigger animated transitions such as sliding, fading, pop in, & flip. This enables you to create very realistic interactable demos of your app. Checkout the demo page for some examples.

Every action you or your team takes automatically creates a revision you can easily revert to.

The UI library is huge and very high quality. All the UI required to design iO7 apps is included as well as iOS 6 and basic wireframing elements. For example in iOS7 it provides:

• Backgrounds
• Navigation & status bars
• Layouts (list pickers, maps, keyboards, scroll etc)
• Controls
• Typography
• Icons

Using the app is feels very snappy.

They have a very reasonable free tier with the paid versions starting at $12/month.

You can preview your designs live in the browser as well as send them to a mobile device to better simulate the UX.

Fluid isn't just about wireframing static screens. You can plan out all the user flows and then define the transitions between them. This is really handy for planning out the entire user workflow.
