This AI built me a mobile app in 14 minutes using GPT 5 (Rork guide)

I found an AI agent running on GPT5 that lets you build entire iOS and Android apps in one single prompt. The best part is you can instantly test the apps on your phone. You enter in a prompt, it builds the app, and you can just start testing it immediately without having to ship to the app store. The AI agent is called ROR. And in this video, I'm going to show you how to use ROR to build out games, productivity apps, and a whole bunch of other mobile apps in seconds. You don't need any programming knowledge at all to do this. The question is, is this better than Claude Code? We're gonna find out. Let's get into it. So, I'm in Ror now, and this is a brand new AI agent powered by GPT5, which is sick. It is dedicated to building mobile apps. So, mobile apps are very difficult to build with AI. The problem is, especially if you're building an iOS app, you need to use Xcode. And Xcode really doesn't have any AI functionality in it. I don't really know what Apple's doing. They just refuse to embrace AI, but whatever. So, building mobile apps has always been a little bit more challenging. You have to open up Cloud Code. Xcode side by side. You work in both of them at the same time. It's just really difficult to use and play with at the same time. Enter ROR, a brand new AI agent where you just put in a prompt. It builds you out a mobile app and you can test it both in your browser and live on your device immediately right after you put the prompt, which is mind-blowing. And I've never seen that before. That's something you can't do with cursor or clawed code. There's no mobile functionality built in to start testing. So, this is going to be awesome to play around with. Just as a side note, shout out to work for giving me access to the app. They reached out to partner with me. They threw me a whole bunch of credits, but they have zero control over what I say in this video. Zero editorial control. I'm going to go through the good, the bad, and the ugly. Nothing will be held back here. We're going to put it through its paces. So, let's do this. We are in Ror now. Let's build out the first app. I want to build a mobile video game. For those who watch the channel a lot, live stream, you know I'm a massive gamer. In fact, the moment this video ends, I'm going to be playing Battlefield 6. But let's build out a little bit of a shooter since we're in the Battlefield mood. Let's do this. Let's build out a 2D space shooter on mobile that we can immediately try on our phone. Let's see if it works. I hope it works. GBT5. So, this should be good.

So, here's the prompt I gave. I'll put this down below, too, if you want to test this out as well. I want to build a 2D sidescrolling space shooter. There should be power-ups, different enemies, bright colors and explosions, and stylistically should be awesome. Make the ships look super detailed and the space background awesome. So, I was very strategic with this prompt. When I prompt to build games, I try to leave a lot of room for creativity from the AI model. I get super specific later, but up front, I just say, "Hey, make this look good. Be detailed. Make it look awesome. Have it have awesome colors. " just so I give the model a good amount of creativity to try different things out because maybe it'll try things I haven't thought about before. So, let's send this prompt out. Let's see what V1 looks like. We're going to test it on our phone to see if that works and maybe we'll add some edits to it as well. So, I'm going to hit enter on this. Ror's going to get to work. Okay, so this is cool. So, it starts off. So, it's going to get to work here. It has a bunch of thoughts. It's planning out the game on the left hand side. On the right hand side, as you can see, you can see the mobile phone. So, you see the iOS device. You can switch to Android or the web. So you can do web apps as well. I like that this is mobile first though, you know, with cloud code and cursor and all the other AI app builders. They're not mobile first. Doing anything mobile is very, very challenging. This is obviously mobile first. And it looks like we're going to be able to test it right off the rip in our browser, but I'm interested to see how I can test this on my phone. So looks like I scan the QR code and I can test it out. So we'll see if that works. So it's planning out the app. It's using GPT5, so it has the latest models. I think it had quad as well. So, you got your choice of whatever you want to use. I'll create an awesome 2D sidescrolling space shooter with vibrant neon aesthetics inspired by games like Geometry Wars. Shout out Geometry Wars. That's an oldie but goodie. Played that a ton on Xbox 360. That was the sickest game. And classic arcade shooters. The game will feature detailed geometric shapes, dynamic particle effects, and a stunning animated space background. Okay, I like the plan. Looks like it's building out all the files. I'm curious to see if I'm going to get a live preview here on the phone. We'll see what that looks like. If I switch over here, we can see all the code. So you code getting built out. That's pretty sick. I'll go back to preview mode. I like the way this looks a little bit more. Looks like there's integrations as well up here. Oh, okay. So you can quickly uh integrate this with like a database. You can connect your GitHub so you can upload the code. Environment variables. Oh, that's helpful that you can just add environment variables like that. So it's building out all the features. Looks like it's creating a ton of files, projectiles, powerups, explosions. All right, looks like it finished building

here. All right, perfect. I've successfully fixed all the TypeScript errors. All right. I didn't even know there were rows. Looks like it just fixes errors on its own and detects them. That's pretty cool. Game features beautiful neon theme spaceship animated starfield background. Drag to move. Three enemy types. Wow. Power-ups, explosion effects. All right, let's do this. Let's see how it goes. So, we got the in browser preview right here. It's called Neon Striker. I like the name of the game. Let's start this. Okay, it's go. Oh, I like the stars are moving in the background. Okay, I'm dragging on the screen to move the ship. That's cool. It auto shoots. Is that enemies or is that a power up? I'm not sure. Okay, so we have these red things flying. I'm going to assume that's enemies. Yep. Boom. Blow them up. That's got to be a powerup. Got that. Oh, now I'm super shooting. So, we got cool powerups. Let's see. Let's go get Okay, so the purple ones you got to shoot multiple times. The red ones die instantly. I like that. I like this. I like the stars moving in the background. That's a nice detail to make it feel like it's moving fast. This is cool. Now, let's do this. Let's Oh, I got a little shield there. That's cool. Let's do this. Let's try this on mobile. So, let's scan this QR code to see if that works on mobile. All right, I'm going to do that. Pull up my camera. Looks like I just scan it. Let's do this. Boom. Open in Chrome. All right, it looks like I need to download an Expo Go app to test it out. So, I'm just going to download that real quick. I got that downloaded. So, now I'm going to hit allow. It opens up Expo Go. Looks like it's loading up the app. Let's go on full screen here. Here you go. Okay, so Neon Striker. There it is. The app is live on my phone. I'm going to try to play it while looking at my monitor to see if I so I can show you what it's doing while I play it. Boom. There we go. Okay, I can control it. The controls are a little tough. It moves faster than your finger, but I'm playing the app live on my phone. It's got the full app live on the phone, which is really cool. And it's like a full screen app. It's like the full app. You ever do like test flight? It's got the full It's got everything. That's really cool. So, I'm able to test it basically immediately on my phone after it builds, which is really sick. So, one prompt and I have an entire game basically playable on my phone. Now, you still need to ship it to the app store to have it in the app store, but testing wise, this is significantly easier than what you do with like clawed code because a cla code you need to go on to Xcode and then you download the package and you ship it to your phone and you got to go on your phone. There's a lot of steps and for someone who's not technical, that's going to be really difficult to do. Uh, but with ROR, you literally just scan a QR code and it downloads it onto your phone through the internet and you can just start playing the game immediately. And then if I wanted to, I could probably just go in give it more descriptions of what I want to build. So say make the enemy ships look like actual spaceships. I hit send on that. Okay, it makes the changes live over here. So it's making the changes. All right, looks like it's done. The ships, okay, that looks like more like a ship. The purple ones, uh, they look a little bit more like a ship than they did before. or the triangles look more like ships. So, it applies the edits you ask for. But overall, I mean, two prompts and I have a working game on my phone. That's pretty sick. Let's do this. Let's now build out a productivity app. I want to test out building like a note-taking app to see if we can build like productivity mobile apps for ourselves. All right. So, I'm going to click here on the left to create a new project and we'll start building out our

productivity app. So, let's try this. I want to build a note-taking app where I can create new notes, see old notes I created, type in different fonts, and even draw on screen. Make the app beautiful. I want to see how this does with like productivity apps. One thing I love to do is I like to build out apps I use daily and just use my own version, right? I haven't built many mobile apps because it was just too difficult in the past to build out mobile apps with cursor clawed code. So, let's do this. Let's start building out mobile apps we use daily. I'm going to build a note-taking app. Let's do this. Let's hit send. So, that gets to work again. Pulls up the iPhone over here on the right. It starts thinking about how it wants to build it. The user wants to take a note-taking app with the following features. All right, it has a bunch of stuff on it, draw on screen. Uh, comes up with a pretty good plan. Part of me wishes there was like a plan mode so I can like type it in and approve things and make sure every step is what I actually want, but that's fine. Hopefully, they add a plan mode later. Checking out what the Android simulator looks like here. Okay. Yeah, basic looking Android simulator. We go to web. All right, your standard website. Let's go back to iPhone. I'm an iPhone guy. Looks like it's creating all the components for every single note, all the tabs, the modal. Okay, it's moving pretty quick there. All right

looks like it was built out. Let's see here. No note. All right, let's create a new note. Start typing. First note. Okay, I can use my keyboard and mouse for this as well. This is my first note. All right, let's see. I change fonts. Oh, we get different fonts. Oh, boom. Look at that. Cool. That looks nice. We go back. Okay, it saves it. What does that button do? just to edit it. Okay, cool. Let's do uh let's just do a second one and test the search functionality out. Second note. This is my second note. Let's say back. Okay, autosave. Now, let's do a search. Do first. Boom. Auto searches. Okay, I like that. Now, let's do this. Let's test out a mobile. Let's test out what this looks like on mobile. So, I'm going to scan the QR code on my phone. Go in full here. All right, so we're going to allow allow. It opens up the app. Beautiful note takingaking app is loading up here. As you can see, camera won't focus, but it's the same UI we were looking at before. Let's create a new note in the bottom right here. So, I click the new note button. Boom. Let's see here. I can type it out. New note testing. Boom. The note goes on there. I like that. And it's a full screen experience. You get the full It's not like it's like a windowed in your phone thing. It's like a full app on your phone. Let's try out painting. Okay. The drawing doesn't quite work. drawing doesn't work, but that's fine. I bet we can edit that. Uh, go back into ROR and edit that. I like that. But it works. I have a productivity note app. If I wanted to just go ahead and I even want to ship this, I can just keep it on my phone and start using it and just use it as my new note-taking app that I built myself. That could be cool. Other than that though, let's see what the process is for putting this on the app store. I'm going to hit publish here in the top right. Let's see what happens. Share a link to your app before going to the app store. Okay, so I can actually take this link and send it to friends if I want other people to test out the app for me. That's pretty nice. That'd be a nice way to test the app out, get it in front of people. Could be a cool strategy to like build out an app in ROR and then tweet out the link and have your followers use it and have them like kind of beta test it. That's kind of a cool idea. Let's see what happens when I click publish to app store. App store submissions. Man your app store submissions or create new ones. Let's do a new submission. Let's see what this process is. All right. So, you got to sign up for an Apple developer membership. Then it looks like you just enter in your app info and submit it. And so, you can do this all through ROR. You can just do the whole submission process through here, which is kind of nice that it streamlines that. So, let's look at pricing. Let's click upgrade here and see the pricing structure. All right. Simple, transparent pricing. $20 a month gets you 100 messages. That's not bad. I sent two messages in this video. One message, actually, I sent three. Two messages for the spaceship app and one for the note takingaking app. So, you could probably get away with doing Junior and just building out your first app and seeing that how that goes. 100 messages should be enough to build out an entire app. For $50, you get 250 private projects, code editor, GitHub integration, chat support. All right, so looks like it scales pretty nice. Uh, I'd probably recommend starting out with the $20 just to see how it goes, see if you like it, see if it's for you. But from a mobile app perspective, I think if you want to build mobile apps, this is the way to go. Again, claude code, cursor, they're great, but they're not built for mobile. You have to download Xcode. You have to run Xcode and cursor side by side. It's a pretty janky experience. You want to test on your phone. It's a 10 other different steps. This is really streamlined where you get to test everything in the browser and then you get to put it on your phone immediately just by scanning QR code and play with it. I'd have to say downsides. I wish it was a little faster. I wish it moved a little faster, but from a UI and UX perspective, this was really easy to do. It has GPT5, so it has the latest miles, which is awesome. Looks like you can upload pictures and say, "Hey, build an app based on this picture. " That's pretty cool. I think what I liked the most though is being able to test it on my phone. And it comes down to this. If

you're interested in building mobile apps, I think this is the best experience you can get for building mobile apps, especially if you want to test it out and you want to do something like me where you can send links out on social media for people to test it like that. That was rather cool. I mean, it does solve a legitimate problem, which is developing mobile apps on the other AI platforms are a pain. You got to set up Xcode. You got to run two IDEs side by side. This makes it easy. If you want to test out RO, I'll put the link down below. Should have a promo code down there as well. I'll put that down there, too. If you're building mobile apps, if you're vibe coding mobile apps, I think this is a must try. I think this makes building mobile apps significantly easier, and I'm sure it'll only get better from here as well. Make sure to leave a like if you learned anything at all.
