About Designer Tools Pro
If you're someone who builds, tests, or polishes mobile apps—whether you're a developer, designer, or someone obsessed with pixel perfection—then Designer Tools Pro might be the most practical utility you haven’t tried yet. Instead of bouncing between multiple tools to measure spacing, inspect alignment, or double-check colors, this app folds everything neatly into one space. It's not flashy, and it doesn't pretend to be—it just gets things done.
At its core, Designer Tools Pro works like a utility belt for mobile interface folks. You’ve got a grid overlay to instantly check layout spacing, a color picker that drills down to individual pixels, and a mockup overlay tool to compare your app’s UI with design files—all while your app is running. And yes, you can adjust the grid size, play with opacity, and tweak alignment without leaving your screen.
The mockup overlay is a subtle but effective way to keep things looking right. By superimposing a static image over your live app, you can do side-by-side comparisons to catch tiny shifts in alignment or off-brand elements. It works for both portrait and landscape views, and if you're fiddling with placement, you can drag the image vertically to line things up exactly.
As for the color picker—it’s basically a digital magnifying glass. You drag your finger across the screen, zooming in on specific pixels to see their hex values. Tap a code and it’s instantly copied to your clipboard, ready for your next Figma board or CSS file. It sounds simple, and it is, but when you’re squinting at two blues that should be the same, it’s an absolute lifesaver.
One thing worth mentioning: it uses Android’s AccessibilityService API to support floating overlays. But according to the devs, there’s no data collection or creepy behavior involved. That level of transparency is honestly refreshing, especially in a world where “background access” usually means something else entirely.
There’s nothing bloated here—no unnecessary extras or shiny distractions. If you're trying to validate UI elements, streamline QA testing, or just want to make sure your colors aren’t slightly off, Designer Tools Pro fits into that workflow effortlessly. It’s less about showing off and more about fixing what matters before your app hits production.
