Hi HN — we’re Seth and Ayo and we’re building a0.dev (<a href="https:&#x2F;&#x2F;a0.dev">https:&#x2F;&#x2F;a0.dev</a>). a0.dev is a platform built to cut down React Native development time from weeks to just a few hours.We’ve been building mobile apps together for seven years and have had several successes. One thing that’s always bothered us though is how much harder it is to build a mobile app than a website. If you’ve built an app with React Native before you’re familiar with the pains of working with both Xcode and Android Studio, writing tons of boilerplate before you can even start making the app, setting up state management, and of course going through the dreaded app review. We decided to build a platform that would make the app development process faster.We’ve seen the success of new code-gen platforms like v0 and wanted something for React Native that goes further. We built an AI app generator that takes a user&#x27;s prompt and creates a custom React Native app with an instant live preview.Here’s a 5min demo where we recreated the Hacker News UI: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;f3lzBRBUous" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;f3lzBRBUous</a>a0.dev is great for quickly prototyping components and screens in React Native and users are able to copy the code from our generator into their preferred development environment. Our landing page has a couple of example prompts, but we encourage you to get creative when trying it out. We’ve had success generating not only functional screens like an Instagram Feed but also 2d games like Minesweeper or Flappy Bird.Our chat has a “UI Expert” and “Advanced Logic” model users can switch between depending on the task at hand. Users can upgrade from working on a single screen to creating a full app by clicking on the “Need a Full App” button in the top right of the page. This changes the scope from a standalone chat with a single file to a full project that can include multiple chats and files. We launched an IOS app that users can download in order to preview the app on a physical device. We find that many apps look and feel better on a physical device so we recommend trying it out.Our goal is to continue to improve the app generator while adding more features to help developers get their apps to the app store and make money from those apps. The main features on our roadmap right now are a Supabase integration and a “one click submit” button to let developers publish their app to the App Store.There are a few limitations to note. We’re working on releasing our Android app, but Android users should be able to preview their app using the Expo Go App. The app is running React Native Web in the browser so any dependencies that don’t support web won’t work with the web preview but should work on the phone. There are also some dependencies that our system can’t handle because they require native modules that aren’t packaged into our app currently.We hope you guys will check it out and try making an app with a0.dev. We’re available on Discord around the clock to help developers with any problems they may face and want to guide people to actually releasing their app on the App Store. Let us know what features you’d like to see and any problems you’ve faced building apps, we’d love to hear about your experience.Here’s the link again to check it out: (<a href="https:&#x2F;&#x2F;a0.dev">https:&#x2F;&#x2F;a0.dev</a>)We dropped the need to sign up for the first message so you can just jump in and try it out.Looking forward to your thoughts!

Is it just me, or does React Native suck? I spend most of my time debugging builds. Is there any alternative to this?

Ask HN: Why React Native Sucks?

Hey HN,Tired of setting up Auth, Onboarding, In-App Purchases, DBs, cloud storage, GPT, OTA updates, deep linking, and more for every project?That&#x27;s why I created QuickWrap - React Native Boilerplate to create AI Wrappers or any Android and iOS apps in minutes.I hope this Boilerplate will be helpful for you as it is for me. Would love to get feedback please.Thanks,

Hello There, 
&lt;p&gt;I want to show you guys and get your feedback for my Hacker News client built using React Native.&lt;&#x2F;p&gt;
&lt;p&gt;This maybe a yet another Hacker News client, but there was an inspiration behind building HackerBuzz, and it was &lt;a href=&quot;<a href="https:&#x2F;&#x2F;github.com&#x2F;simonhalvdansson&#x2F;Harmonic-HN&quot;&gt;Harmonic-HN" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;simonhalvdansson&#x2F;Harmonic-HN&quot;&gt;Harmonic-HN</a> by Simon Halvdansson&lt;&#x2F;a&gt;, I saw this app and instantly fell in love with its workings and functionality, and wanted to build something like this by myself, hence started working on HackerBuzz&lt;&#x2F;p&gt;
&lt;p&gt;Both code and app might not be perfect and could have problems(that I would love feedback on), but I&#x27;m feeling good to show my work to you.&lt;&#x2F;p&gt;
&lt;p&gt;Here is the repo: &lt;a href=&quot;<a href="https:&#x2F;&#x2F;github.com&#x2F;ajshrmaofficial&#x2F;HackerBuzz&quot;&gt;https:&#x2F;&#x2F;github.com&#x2F;ajshrmaofficial&#x2F;HackerBuzz&lt;&#x2F;a&gt;" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ajshrmaofficial&#x2F;HackerBuzz&quot;&gt;https:&#x2F;&#x2F;githu...</a>, and apk is also available at release section.&lt;&#x2F;p&gt;
&lt;p&gt;Start the repo if you like it, feel free to give suggestions.&lt;&#x2F;p&gt;
&lt;p&gt;Thank you all ;)&lt;&#x2F;p&gt;

Show HN: HackerBuzz an cross-platform HN client built using React Native

There comes a moment in every Hacker News reader’s journey when they drift from simply browsing to crafting their own ethereal client—only to find themselves drawn back to the original, like a cosmic cycle of creation and return. I suppose this is my turn in the stars.Also, if you&#x27;re up for an adventure, I’m looking for beta testers for the Android app. It supports authentication, upvotes, and comments—things the official API doesn’t cover. Since that means setting up a server and optimizing requests, I’d love some early feedback before making it fully ready. Let me know if you&#x27;re interested!Current Features:- Things just work(RN is kinda tricky and so non-uniform in complex apps)- Markdown support for comments without Links(integrating both was difficult)- Endless scroll up to 10 pages on &#x27;Top Stories&#x27;While I’m here, I’d love to ask—would you be open to paying just $1 for a one-time purchase on Android and iOS? It would help support development and fund a one-click production framework and deployment platform I’m working on.What else would you like to see in Hacked?

Hey HN, we’re Daniel and Daniel (the Daniels) from aSim (<a href="https:&#x2F;&#x2F;asim.sh&#x2F;">https:&#x2F;&#x2F;asim.sh&#x2F;</a>). aSim is a mobile app that can generate immediately usable and shareable mobile apps from your phone.Tools like bolt.new and v0 have made it easier to build websites by just chatting with an LLM, but things have been lagging on the mobile side. We’ve always been suckers for well-made mobile apps, but today, it is still extremely difficult to build mobile apps with LLMs on your computer, and nearly impossible to do it from your phone.We built aSim to make it easy to build prototypes, “trinket” apps, or just random fun things all async from your phone. You can check our landing page (<a href="https:&#x2F;&#x2F;asim.sh&#x2F;">https:&#x2F;&#x2F;asim.sh&#x2F;</a>) for some ideas of different types of apps. Hopefully we can bring some life to your side project graveyard, or at least make the graveyard even more numerous.Here’s a demo video of the generation process: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;_3VCl13oMGc" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;_3VCl13oMGc</a>And here are the actual one-shotted apps I made in that video:- <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157003&#x2F;make-an-app-where-i-can-upload-an-image-and-it">https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157003&#x2F;make-an-app-where-i-can-upload...</a>- <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157014&#x2F;make-me-an-app-that-is-a-clone-of-yikyak">https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157014&#x2F;make-me-an-app-that-is-a-clone...</a>- <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157006&#x2F;make-me-a-chess-timer-app-for-in-person-chess">https:&#x2F;&#x2F;asim.sh&#x2F;@dli&#x2F;s&#x2F;157006&#x2F;make-me-a-chess-timer-app-for-...</a>All of our app generations also get access to a set of APIs that help get the ball rolling on some basic functionality. These APIs range from LLM usage and image generation to having shared state with your friends, and globally among all users. We’re always on the lookout for new API integrations (i.e. Spotify and Maps) so please let us know if you need any!We’ve had a small cohort of beta users that have been making what we think are some pretty cool apps. Here’s some of our favorites:- Pokemon-style Gacha Game - <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@evan&#x2F;s&#x2F;126948&#x2F;elves-vs-monsters">https:&#x2F;&#x2F;asim.sh&#x2F;@evan&#x2F;s&#x2F;126948&#x2F;elves-vs-monsters</a>- OpenStreetMap stats: <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@lake&#x2F;s&#x2F;104102&#x2F;osm-stats">https:&#x2F;&#x2F;asim.sh&#x2F;@lake&#x2F;s&#x2F;104102&#x2F;osm-stats</a>- Star wars idle game: <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@jojaspero&#x2F;s&#x2F;29102">https:&#x2F;&#x2F;asim.sh&#x2F;@jojaspero&#x2F;s&#x2F;29102</a>- Find your Meyers Briggs - <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@typewhisperer&#x2F;s&#x2F;135964&#x2F;jung-mirror">https:&#x2F;&#x2F;asim.sh&#x2F;@typewhisperer&#x2F;s&#x2F;135964&#x2F;jung-mirror</a> (&lt;-- just for fun, you don’t have to believe in MB :))- AI Tic Tac Toe - <a href="https:&#x2F;&#x2F;asim.sh&#x2F;@hashmelons&#x2F;s&#x2F;105561&#x2F;ai-tic-tac">https:&#x2F;&#x2F;asim.sh&#x2F;@hashmelons&#x2F;s&#x2F;105561&#x2F;ai-tic-tac</a>Behind the scenes, we’re generating a modified version of Typescript React Native that can be parsed and compiled into simpler instructions that can be sent to mobile devices on the fly. We’ve ripped out some parts of the TSC library, as well as lean heavily on AcornJS to massage the (mostly usable) LLM code into something that can actually be run. We have a bunch of static analyzers, as well as leaning on web runtimes to catch runtime errors (as well as take screenshots), though at the very end of the day, we lean the most on our users to play around with their creations and remix them into something great.It’s currently completely free to use, so we hope you check out aSim at <a href="https:&#x2F;&#x2F;asim.sh&#x2F;">https:&#x2F;&#x2F;asim.sh&#x2F;</a> and enjoy it as much as we have while building it! Let us know what features you’d like to see and any problems you have with your generations.

Hi HN, I’m Pablo, I built this application to learn languages using podcasts:<a href="https:&#x2F;&#x2F;www.langturbo.com" rel="nofollow">https:&#x2F;&#x2F;www.langturbo.com</a> (No signup required)There are a lot of tools to learn languages, but most of them focus on beginners (understandably so, that’s where the money is) but not many exist that target intermediate or advanced learners. The ones that exist make you find content on your own and then import that into their apps, which can be tricky when you don’t know where to look.LangTurbo has a unique curated database of podcasts by language (some even have dialect labels) that you can browse by topic, or search by keyword, so you can discover content and learn in the same place.Having a good language learning method is important, but having the motivation to keep learning is much more important. Some tools like Duolingo try to keep you motivated with “gamification”. I don’t like that, I think it gives you a false sense of accomplishment without real improvement. The way LangTurbo tries to keep you coming back is via the content itself. My goal is that you discover some podcast that interests you enough to keep coming back to listen to new episodes, the same way you listen to podcasts in your native language. I wrote more about the method here [1]The app also lets you learn without looking at the screen, you can listen to a podcast in the background and for each sentence you will first hear the translation in English and the native speaker after. I call it “poor man&#x27;s Pimsleur mode”.Some things I learned while building the app:* Currently the best SRS algorithm is FSRS, the app uses this algorithm implemented in SQL (thanks to [2])* Working with Expo (React Native) was a great experience, the app has web, iOS and Android (coming soon) clients sharing most of the codebase.* A lot of non-English podcasts have a feed with English as the language. I had to build a “probe” to get the correct language of a podcast, based on the text and audio of the feed.* Podcasts use “Dynamic Ad Insertion”, that means the content of the audio can change according to the request IP or the time of the request.* Still amazed by all the things Postgres can doLet me know what you think, happy to answer any questions.[1] <a href="https:&#x2F;&#x2F;www.langturbo.com&#x2F;blog&#x2F;langturbo&#x2F;getting-started" rel="nofollow">https:&#x2F;&#x2F;www.langturbo.com&#x2F;blog&#x2F;langturbo&#x2F;getting-started</a>[2] <a href="https:&#x2F;&#x2F;github.com&#x2F;sivers&#x2F;srs">https:&#x2F;&#x2F;github.com&#x2F;sivers&#x2F;srs</a>

Hi HN,I love newsletters. I first started signing up for Market Briefs right after COVID—trying to figure out why everyone was so scared of another market crash. It was exciting at first, but juggling a startup meant I couldn’t keep up, and soon my inbox was a mess of unread emails. I’d often ask myself: do I read them all, or delete and start fresh?That’s why I built LoomLetter—a simple iOS app that pulls in all your newsletter emails into one place, lets you organize them into custom lists, and even reads them aloud using AI. I built it as a one-man project to solve my own problem of newsletter overload.What it does:- When you sign up, you get a unique LoomLetter email address for your subscriptions.- All issues land in the app, where you can sort them (like “Must Read” or “Tech News”).- The standout feature for me is AI-powered narration—turning newsletters into a hands-free. I parse each email’s content and use a speech synthesis API to generate the audio. It’s not perfect yet, but I’m iterating to improve clarity for long reads.I’m also experimenting with features ai summary (recently released) and bulk actions (wip). Currently, it’s iOS-only (built with React Native, Swift, AWS, and Supabase). I’m considering Android or even a PWA next—if there’s enough interest.I’m facing some churn and trying to figure out what makes users stick. For instance, I’m testing a requirement for subscribing to at least two newsletters before joining. I’d love to hear your thoughts on:- Does this solve a real problem for you?- What might make you keep using an app like this?- Any ideas on improving retention?If you’re curious, you can check out the app on the App Store called &quot;LoomLetter&quot;. Thanks for reading and for any feedback!
