I am canceling my subscription. ### 1/5 — Entire Preview Offset *2017-07-07, version 2.25* The entire "screen" for the app that I created and am previewing is offset up and to the left. Previewing iPhone 7 app on a 7+. It cuts off about a quarter to a half inch on the left and top. The opposite edges show white. This makes app useless to me. Back to computer preview :( ### 2/5 — Projects are broken on iPad *2017-04-28, version 2.25* Videos & transitions won't load when opened on iPad. Fix or this app is useless. ### 1/5 — On Device is broken iPhone and iPad *2017-01-29, version 2.25* Opening my app prototype On Device produces a black screen permanently, on iPhone 7 and iPad Pro. Blocks my testing. Submitted bug report with steps to reproduce in December. Repeatedly told they will update my case. Tools were good for building the prototype. Wasted time so far. ### 4/5 — Great app, but *2016-12-02, version 2.22* I edited one of my prototype screens but it wouldn't save the changes and interactions that I made. I saved the changes on my mac and then restarted this app, but the changes weren't there. Otherwise great app that has been working so far except for that. ### 1/5 — Crash *2016-11-22, version 2.22* It crashes when you try to download a project. What is the app for? ### 1/5 — Doesn't work on iOS 10 *2016-09-30, version 2.13* Awesome app but doesn't show prototypes on iOS 10 just s white screen ### 3/5 — Please fix a bug *2016-09-19, version 2.06* There is a bug that keeps closing the app when I load a project:/ ### 2/5 — So lame *2016-09-19, version 2.06* Was definitely a good app - but to be crashing on ios10 - you'd think they would have been proactively testing? Now I'm unable to demo to my clients - last minute. Will start checking out InVision - they seem more on their game. ### 1/5 — Crashes with ios10 *2016-09-16, version 2.06* Update it!!! ## Most critical reviews (10 lowest-rated) ### 1/5 — 13 pro max doesn’t work *2024-11-02, version 2.43* Can’t login. ### 1/5 — Didn’t let my close my account *2023-04-04, version 2.40* Took me a long time to delete my account as every time I pressed delete it would direct me back to the same page. Still not sure if I have deleted it now as after I have ‘deleted’ my account it left me on a blank page so I could not double check if I have deleted it or not as I do not want to pay the subscription fee. ### 1/5 — Share link, Login issues *2019-08-15, version 2.32* Can’t view shared links or log in with credentials, currently support is slow to respond ### 1/5 — bad *2019-08-10, version 2.32* bad ### 1/5 — Cannot sign in *2019-05-16, version 2.32* I can’t even sign up with this app It says sign in only How can i sign in when I don’t have account or sign up with this. Frustrating ### 1/5 — Don't want *2019-03-26, version 2.32* I don't want this app, I didn't ask for it, how do I get rid of it? ### 1/5 — VR Prototyping is Broken 😭 *2019-03-26, version 2.31* Can't use Google cardboard to test VR prototypes because the images aren't aligned properly. iPhone X. Must be due to the notch. This has me sad. 😭😭😭 ### 1/5 — Not that great *2018-11-02, version 2.31* Website is great until u have to download this app that doesn’t work at all. Like at all ### 1/5 — This deserves 0 stars *2018-04-24, version 2.29* I’m cancelling my subscription. What a waist! ### 1/5 — Got a blank screen *2018-02-24, version 2.28* I would rather use the browser to view prototypes. ## Most praised reviews (10 highest-rated) ### 5/5 — Awesome Product *2021-06-23, version 2.37* This service made prototyping so simple.I am not a graphic designer and I’ve never made a prototype before, however, this software made it possible with relative ease. It has powerful features and functions that make prototyping easy, simple, and quick. I’m very happy I found this service. ### 5/5 — Really good *2020-09-28, version 2.35* The prototype is responsive and easy to use and it has live updates from your computer to your phone. Really love it, it’s helped me build my prototype. ### 5/5 — Amazing *2020-06-12, version 2.34* Have been using this service for quite a few months now and it’s an incredible way to flesh out an idea. Little bumps and glitches along the way are fixed when you ask the online support who are really helpful. Cool service ### 5/5 — Great *2020-04-28, version 2.34* Wonderful job ### 5/5 — Exceptional *2020-03-23, version 2.34* This is really remarkable software. Almost no learning curve, and outstanding functionality. Stoked! ### 5/5 — Excellent iPhone and iPad app *2020-03-08, version 2.34* Surprised many of the other reviews here are experiencing bugs, I’ve been using the app every day for 2 week with no issues. I originally was using Figma’s Smart Animate feature but performance was unreliable and it lacked a timeline so I switched over to Proto.io. ### 5/5 — By far the best *2020-02-09, version 2.34* This is by far the best prototyping platform available. The extend to which you can control details about animations and user interactions completely surpasses that of Adobe XD. I would like to see update UI elements for iOS 13 but other than that it's brilliant. ### 5/5 — An excellent tool for prototyping *2018-03-20, version 2.28* A well-designed, intuitive tool for testing. Proto has helped our team to rapidly prototype new game mechanics for title that we’re developing. I love the interface, and the ability to test our ideas with people across the world. Proto makes it easy for non-technical people to come up with really compel, robust, believable experiences. Hugs thanks to the Proto.io team! ### 5/5 — Colorcubic *2018-03-07, version 2.28* Literally started using Proto.io not even 24 hours ago. As an animator & UiUx designer, prototyping has always been somewhat of a pain for me. Only because the tools available have really been subpar, and severely lacking in animatable features. As a result, I had to make up for the lack of animatable capabilities in a lot of the prototyping tools available, by utilizing After Effects to mock-up user experience and build out dynamic prototypes to share with developers and investors. Since using Proto.io, within 30 minutes, I was able to mock-up a fully functional prototype, with really attractive dynamic transitions and animatable gestures. I read the reviews on here, but thought I would give it a try myself. 1). I haven’t experienced anything that those leaving negative reviews have experienced. Which tells me that the team behind Proto.io listens to customer feedback, and works diligently to resolve any discrepancies. 2). Their mobile app works marvelously to be able to share prototypes with colleagues and team-members. I also like that any changes to the prototype through their web app instantaneously updates through their mobile app. Just simply requires a three-finger tap, and select the reload option, and all of the new changes have been propagated. After extensively exploring alternative prototyping tools, I have to say, proto.io is killing it. Looking forward to exploring their other tools, and to see what else they roll out. ### 5/5 — Proto is outstanding! *2016-10-10, version 2.13* This product took brought my idea to life. Extremely intuitive and easy to use with exceptional and quick customer service from the proto help team. Showing my prototype to people has blown them away (and I don't know the first thing about coding). I'd recommend this product to anyone looking to build an app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
