Ranked in these QuestionsQuestion Ranking
Pro Tools for team collaboration
Work with your team on a design. Connect on live video calls and chat or add comments.
Pro Supports realistic gestures & transitions
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.
Pro Awesome version control
Every action you or your team takes automatically creates a revision you can easily revert to.
Pro Provides UI assets from all the versions of iOS
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:
- Navigation & status bars
- Layouts (list pickers, maps, keyboards, scroll etc)
Using the app is feels very snappy.
Pro Free forever for a single project & 10 screens
They have a very reasonable free tier with the paid versions starting at $12/month.
Pro Lets you test on an iPhone as well as in the browser
You can preview your designs live in the browser as well as send them to a mobile device to better simulate the UX.
Pro Makes it easy to plan out the app workflow
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.
Pro User friendly
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.
Gravit is completely free to use.
It was open source up until a recent release, however there are plans to open source it again in the future.
Pro Multi platform
Works on Windows, Mac and Linux.
Pro Actively developed
Pro Has almost all of the features of more expensive applications
Has comparable features with applications that normally cost a monthly fee.
Pro Easy to export all assets
Gravit has a built in exporter to PDF, JPG, PNG and SVG.
Pro Easy to design multiple pages
The ability to assign layers to specific pages, and view single or multiple pages at once makes it easy to design an entire website without getting lost in thousands of layers. Easy to view multiple pages at one time.
Pro Clean and helpful UI
The panels in Gravit adjust to contain the information needed based on the type of element selected, preventing the clutter that Photoshop often experiences.
Pro Symbols and libraries
With Gravit you can re-use the same design for buttons, inputs, etc, in multiple places, with changes synced every where the element is used. It's also possible to set text to a shared style to sync text changes throughout the app.
Pro Able to open Sketch files
The ability to open Sketch files makes it easier for Linux/Windows users to collaborate with people who use Sketch, which is macOS specific.
Con Changing rapidly
The fast rate of growth/change for Gravit can be a pro in that in means plenty of new features.
However, it also makes the product fairly unpredictable.
For example: In the past year, Gravit was open sourced, then closed sourced again.
Con This does not appear to be a Web-design tool
Gravit appears to be a vector-art tool, and nothing more. Their homepage doesn't even mention Web design as far as I can see.
