me: you can build mobile apps from your phone! Steve Wozniak: "wow, unbelievable" Apple App Store: you can't.

Imagine your app updates could "hot reload" on your users' phones... Oh wait, with @CreateWithBloom this is already possible!
Going on day 3 of "Waiting for review" 😢🤦‍♂️

I am building an Image resizer Android app using @CreateWithBloom for student who fill exam forms for Indian government exams. it's real pain when you try to upload your image or signature to any forms, cause there are certain requirements for each forms - - Custom sizes - Pixels boundation -(eg. 30px -50px for signatures) and some other pain points. i am trying to solve that with @CreateWithBloom here is the initial version of the app i have build with signle prompt. #Bloomathon

I built a gamified life improvement mobile app in under 3 hours using bloom.diy . @CreateWithBloom No joke, it handled the database, auth, API connections, and even the full UI. All I had to do was refine the prompt. What really blew my mind: - Super fast iteration - Feels like coding at 10x speed - Full project ready to download as a ZIP -It even debugs errors for you once it detects issues in the logs They’re also giving tons of free credits right now, so make sure to check their socials.@CreateWithBloom

i feel sad for those who haven't tried bloom yet real software can now be built by anyone anywhere in the world just with access to a phone and this is only the beginning, these guys have been cooking and the foundation is solid af

What’s happening here matters beyond Bloom. We’re watching the cost of building real software collapse. Things that used to require a full team can now be built by one person with taste, technical judgment, and the right tools. That should expand what gets made. Instead, Apple is shutting down an entire category before it really has the chance to exist.
Apple is banning vibecoding apps. A new generation of personal software is emerging, and Apple is blocking it from reaching iPhone users. Everyone can build apps now. Just not on iPhone.

Biggest update I’ve ever shared… @CreateWithBloom raised $3.4M to unlock the creator economy for software. Let’s be honest: web apps are easy, but building and sharing mobile apps sucks - XCode builds, Apple Developer reviews, TestFlight invites… all make going from idea to an app on users’ hands a slow and painful process. With Bloom you can make a full-stack mobile app by talking into your phone and then share it instantly with a single link. --- Bloom started last Christmas. After landing in Barcelona to visit family, I immediately asked my mom where I could buy a monitor. She was confused, but I was on a mission: I needed those two weeks to run experiments on an idea that had been floating around in my head for months – could I build a mobile app that builds mobile apps? This wasn't just any idea. It was the kind that kept me up at night. I wanted to see if this pipe dream was technically feasible – could we dynamically change a mobile app's functionality on the fly? I came back to Zurich with something promising, but nothing definite. In mid-January, I had a critical conversation with my co-founder @sirian_m. We were making steady progress with our previous product, Fireview, but I couldn't shake this feeling about Bloom. "This could be extremely big," I told him. "It could change the world. It's probably the coolest product we could ever build." With the YC application deadline just three weeks away, we pivoted and scrambled to build an MVP. After submitting our application at midnight, Sirian stayed up until 4 AM recording our demo. Once David Lieb saw our application, things moved fast and we got to spend three intense months in San Francisco with YC. We closed our round 5 days before demo day and didn't have a deck - our product demo did all the talking. --- This $3.4M round is led by @Moonfire_VC , with participation from @ycombinator and @pioneer_fund We're also backed by an incredible group of founders and operators @Thom_Wolf (Founder/CSO, HuggingFace) @bobvanluijt (Founder/CEO, Weaviate) @jamwt (Founder/CEO, Convex) @theo (Founder/CEO, T3Chat) @Baconbrix (Expo) @cedric_dev (Expo) @colinevans (OpenAI) @ron_besseling (Whatsapp) Clive Anyonye (Meta) Robert van Gaal (Google, Vesper) @nicklenten (Founder/CEO, Ahead Health) @HelenaGagern (Founder Embassy) @chrissmoak (serial founder & YC alum) Gianmaria Sbetta (Google) @rdominguezibar (Founder, VC Corner) Special thanks to those who believed in us from the beginning: Founderful Campus, @design_nocodeio, @chaseumms , S2S, @jamwt , and @dflieb We're now back in Europe, building out the founding team that is going to redefine how the next wave of apps is built. If you’re someone that loves building product, solving complex problems and working on the future of software, we’d love to talk. There's so much to build, and we're just getting started. If you want to fast track your application or know anyone who would be a fit, comment with “Join Bloom”

@karpathy vibe coded this iOS app and "had it running on his phone later that day" I recreated the app with @CreateWithBloom in minutes and had it running natively on my phone seconds later. Don't believe me? Open the app here: app.diy/additional-meadowlar…

We met @itsdavidalonso and @sirian_m from @CreateWithBloom, which allows people to build and share mobile apps in seconds. Their product lets you vibe code cross-platform apps and test them on your phone natively. It deploys a backend for you, so you can build functional MVPs and personal apps, not just toys.

I never learned how to make mobile apps and I guess now you can type a prompt and a whole iPhone app pops out...

We built app sharing into Bump in 2010, but all we could do was pass App Store urls. Cool to see *native apps* shared via “bump”. (Oh and also cool you can make a fully featured native app in natural language right on your phone!)
