Handing over your designs to Developers (or picking up designs from a Designer) can prove tricky if you're working on the web or with class libraries like Tailwind. Being able to easily translate those pixels into flexible units is a must so with Hand››over you now can. Rem • Convert any number from pixels to ems/rems • Change the baseline pixel value to whatever you want it to be and see the relevant changes in em conversion • Change the conversion scale so you're not stuck with a 1.000 scale • Convert from ems/rems back to pixels at any time Tailwind • Find the correct Tailwind class value • Change the baseline pixel value Line-height • Find the perfect line height based on a pixel size • Change the conversion ratio based on you need • Swap between scale or percentage based conversions Radius • Live preview combined radii based on either an inner or outer radius value and its padding You can also save any of these conversions to your Saved list and see the latest saved result pinned to a home screen widget. ## Key features - Convert pixels to ems/rems - Adjust baseline pixel value - Change conversion scale - Convert ems/rems back to pixels - Find Tailwind class values - Calculate line-height - Preview combined radii ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/handover/id1518887590/reviews.md ### 5/5 — Great updates! *2020-07-27* Great job with updates! Just wanted to point out a very minor UI issue. The label, “Pixels to convert” gets cut off on my iPhone SE where the viewport is 320x568. It appears as “Pixels to con...” Also, very minor, when the keyboard slides up, the bottom of the green outlined input fields are partially covered, where the bottom rounded corners begin. Extremely minor but wanted to share that observation. Again, great job overall! Thanks for making this app! **Developer response:** Thanks so much for your review man! These pieces of feedback are super helpful and actually two things I have been thinking of changing myself so I’ll bump them up in my list 😊. Update: I’ve completed these updates and have pushed to the App Store. Keep an eye out for version 1.3! ## Frequently asked questions about Hand››over ### What is Hand››over used for?
