A prototyping service that lets you create mobile prototypes with screens designed directly in the online editor or added as images from Sketch or Photoshop. Marvel lets you link all your designs together with gestures and transitions to make your prototype feel just like a real app. Once your prototype takes shape, you can share your projects and get real-time feedback on your designs. Clients and colleagues can comment directly on each screen or drop annotations. There are also Marvel apps for iOS and Android that let you create prototypes from paper sketches and download offline prototypes including Apple Watch.
Instabug helps you collect feedback and bug reports from your users and testers by simply shaking their phones. Comprehensive reports are forwarded to Instabug’s dashboard including complete app data, device details, and most importantly, the reproduction steps.
