Designer Tools

Developers, have you ever wanted to check that you implemented UI designs to specifications?

UX Designers, Have you ever wanted to validate a color or design?

The Designer Tools provides a set of functions for reviewing and validating application specifications. Whether you are reviewing the main lines or a shade of blue, you definitely want to add this app to your toolkit. Even if you provide red lines, this is a great way to check every pixel.

Grid Overlay – Quickly change on-screen grids to check layouts for mismatched gaps or misaligned elements. You can even customize the grid size and font colors.

Mockup Overlay – Display a mockup over your app. This gives you a high-fidelity opportunity to see how the design specifications align with the developed user interface. Choose between vertical or horizontal overlays and adjust opacity for an effective comparison.

Color picker – Use your finger to drag a magnifying glass to select the pixel-level hex color codes.

Screenshot details: Add a panel to all screenshots that shows information about the device, screen, and Android version. The quality assurance teams will love this.
