Essential. Timely. *2022-03-19, version 8.7* @Apple hire this developer to help write all your documentation and make example apps. ### 5/5 — Essential Tool *2021-10-26* This honestly is the most essential tool for every iOS developer. It is my go to reference for all system defaults and I think it should be linked from the official apple documentation. ### 5/5 — Handy Tool for Developers *2020-11-19, version 7.4.1* Extremely thorough interactive examples of all sorts of UIKit layout. I don’t use it often, but when I need to (like today), it saves a ton of time. (Today I was playing with pointer interaction—when I said thorough, I meant it.) And there’s a detailed manual! ### 5/5 — Andrew *2020-10-13, version 7.2* A fantastic App. This really is a must have tool for complex app layouts and designs. It helped make my life a lot easier finding dimensions quickly for ever common interface keyboard and view imaginable. Thank you!! ### 5/5 — Ultra complet ! *2020-10-02* Même si tout n'est pas forcément intuitif ou simple d'utilisation dès le départ, l'outil est redoutable car il va chercher le moindre détail. Des choses auxquelles ont ne pense pas. 5 étoiles bien méritées. Dommage que l'app Watch soit en revanche si limitée. Je pense que c'est plutot une contrainte de l'appareil compte tenu de la qualité du reste. Bravo ! ### 5/5 — Worth paying for *2020-09-24, version 7.1* This app saved me a boatload of design and development time, which is pretty amazing because I don’t own a boat. ### 5/5 — Only batteries are not included! *2020-09-17, version 7.0* The developer seems to have thought of everything I could think of, and some I’d not, to provide configuration information dynamically for your iOS and iPadOS apps. It’s SO much more useful than dry, static dimension figures - this shows you right there and then on the device you’re using. Excellent. ### 5/5 — Very useful *2020-09-07, version 6.3* It is really helpful for developers. It displays all the relevant information for UI development/design in your real device. It shows info like layout margins and constants like system colors or fonts. Definitely recommended ### 5/5 — Instant buy *2020-08-16, version 6.2* Great app, essential resource. ### 5/5 — Amazing !! *2020-05-27, version 6.1* Thank You ### 5/5 — Génial ! *2020-04-13* Super utile comme app, pourquoi je ne la connaissais pas encore ?! Merci Sean Allen pour en avoir parlé :) ### 5/5 — Great app *2020-04-06* Read about it on HackingWithSwift and I’m completely amazed. Literally takes many things out of Apple’s HIG and presents them in a visual way, even learned some new things about iOS development guidelines ### 5/5 — Amazingly good *2020-04-01, version 6.0* This is my best companion to developing natively-looking iOS apps. Thanks for keep it updated. ### 5/5 — Must have for any ios and mac dev! *2020-03-30* Nothing to say more. Thank you for the app! ### 5/5 — A great addition to the iOS app *2020-03-30, version 6.0* Having bought the iOS app I was confused by the price showing. Apple's universal purchase won't charge you a second time.. the UI looks says it's going to on one dialog, then say's it's a free upgrade so have faith. The app iteself is invaluable if you're dealing with any type of app layout design work, highly recommended. ### 5/5 — A must have for developers! *2019-12-10* This tool is invaluable, and all developers should check it out! It’s super helpful to be able to check out SFSymbols on the fly, and test different system materials against your custom backgrounds. ### 5/5 — A must have in a developer’s toolkit *2019-10-26* If you’re serious about being an iOS this should be on your phone ### 5/5 — Excellent *2019-10-18* I am glad I stumbled across this little gem. Very useful tool for App developers. ## Most critical reviews (10 lowest-rated) ### 1/5 — 1 *2024-09-10* 不是我就下载了一下什么就扣，我76块钱我根本就不知道这是什么东西。 ### 3/5 — It good, but I wish it had a simple experience to understand everything *2020-07-11* Its a good app to see different kinds of modals, it would be excellent if the team added ability to enable grids on the phone itself — to see “inspect elements” for iPhone, **Developer response:** There is no team, just me! I don’t quite understand what you mean by “Enable grids on the phone itself’ or “inspect elements”. It sounds like you might want the app to be able to show data on top of other apps. That is impossible. Rather than try and discuss this further via app reviews, please email support@hacknicity.com ### 5/5 — Great Dev app! *2023-12-31, version 9.5* Even if you don't need the measurement tools - this is a great way to find system fonts and colors and smart collections of SF symbols. Buy this app - it will help you somewhere! ### 5/5 — An absolute staple for app developers!! *2023-10-10, version 9.5* I use this app nearly every day for both my day job and my hobby apps. It’s absolutely indispensable! ### 5/5 — Knowledgeable *2023-09-24* It’s good to have the knowledge at hand, if you try stuff out. ### 5/5 — Incredibly useful *2023-04-20* A remarkably useful tool for developers. ### 5/5 — Very helpful *2023-02-18* This is a very nice tool for developers! Thank you for making this app. ### 5/5 — Just Buy It *2022-12-22, version 9.3* absolutely invaluable tool for developers of any Apple platform. reading docs, tutorials, HIG, etc is one thing. but actually being able to see, play with, and explore all the platform provided UI mechanisms on an actual device provides nearly limitless inspiration for my own apps. there’s just sooooo many nice things about this tool, trust me it’s worth it’s price of entry. this is one of a few dev tools i’m happy and eager to recommend to fellow devs and coworkers ### 5/5 — Amazing dev utility *2022-09-30, version 9.1* Thank you for making this, and for making it as good as it is! ### 5/5 — Great App *2022-09-12, version 8.12* Overall this is a great App for every indie app developer ## Most praised reviews (2 highest-rated) ### 5/5 — Have all the answers *2022-05-31, version 8.8* Adaptivity has been incredibly useful, especially for someone like me with the design talents of a dead fish and the income of a busker preventing me from paying a real designer to help me build apps. I have this app open just about every time I’m using Xcode. ### 5/5 — Essential *2022-03-19, version 8.7* How are people building apps without this!? Get it now. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
