Ship native iOS apps
your clients love —
without hiring a single
iOS developer.
We're a senior Swift & SwiftUI team that builds under your brand. Same time zone as your team. One-third the cost of a US agency. Fixed-price projects, capped under $15K.
No sales pitch. We'll review your project, tell you if we're a fit, and share a fixed quote within 48 hours.
You won the iOS project.
Now what?
Hiring a senior iOS engineer in the US takes 4 months and costs $180K a year. Freelancers ghost. Offshore shops deliver bug-ridden React Native and call it native. We built this studio to fix that.
You can't justify a $200K hire for one project.
"I'd need 6 months of pipeline to break even on a senior iOS dev."
We're project-based, fixed price, capped under $15K. Hire us per project, not per year.
Your client is in Chicago. Your last dev was in Manila.
"The 12-hour delay killed every sprint."
We're in Argentina, GMT-3. Your morning is our morning. Daily standups. Real-time Slack.
Your last vendor shipped a WebView and called it native.
"Two months in, I realized the entire app was Cordova."
We write Swift & SwiftUI. Period. No React Native. No Flutter. No WebViews.
Native iOS apps,
pixel-perfect.
We've delivered pixel-perfect native iOS apps that delight users and drive results for our agency partners. Beautiful native iOS apps that earn five-star reviews and repeat business for your agency.
We work behind your brand.
Your client never knows we exist.
You stay the agency of record. You own the relationship, the contract, and the IP. We're the senior iOS team you wish you had on payroll.
Kickoff
You send the brief, designs, or just an idea. We come back in 48 hours with a fixed scope, fixed price, and fixed timeline. No "let's see how it goes."
Build
Bi-weekly TestFlight builds. Async standups in your Slack or Linear. Code pushed to your GitHub org from day one. You demo to your client. We stay invisible.
Handoff
We submit to the App Store under your developer account. You get the full Swift codebase, documentation, and a 30-day post-launch warranty. Every line of code is yours.

The questions every
US agency asks before
saying yes.
Straight answers. No marketing fluff. If you have a question we haven't covered, email us at frank.obarrio@ioslatam.studio or call +1 (305) 709 0655.
Three things no other shop
in our segment offers.
We're not trying to be everything to everyone. We've made three operational commitments that other agencies can't or won't match.
The 48-Hour Quote Guarantee
Send us a brief on Monday. Get a fixed-scope, fixed-price proposal by Wednesday. If we can't quote in 48 hours, we don't take the project. Other shops take two weeks to send you a Google Doc.
The $2,500 Paid Pilot
Don't believe we're senior? Start with a 2-week paid pilot. Build a real feature or fix a real bug. If you're not happy after week two, walk away with the code, no questions asked. Toptal won't do this. Indian shops won't either.
Senior-Only, Native-Only
Two rules we don't break: every developer has 6+ years of native iOS experience, and we only write Swift and SwiftUI. If your project needs React Native, Android, or a junior dev to save costs, we'll tell you to hire someone else.
Meet the engineers
who'll write your code.
No outsourcing chains. No "we'll match you with a developer." This is the team. They show up to the kickoff call and they ship the app.
A full senior iOS team for your agency
ready in days
Pick a 20-minute slot. We'll review your project, tell you honestly if we're a fit, and send a fixed quote within 48 hours of the call.
