Rapptr is a partner in all aspects. They are IN the boat with us. I could tell from the beginning that Rapptr would be a great partner and help us figure things out.Kelly PlummerDirector, The Tapping Solution
The difference
An agency that works like your own team.
Most outsourced teams keep you at arm's length. Weeks billed learning your codebase. A status call to find out what shipped. Work you can't see until it lands.
We join your team instead, and the record comes with us. Two Google Play App of the Year awards, and apps serving over 10 million people a month.
You own the roadmap. We build it with you.
What we do
Everything it takes to ship.
Take a product from idea to launch, or bring in one discipline to fill a gap.

The thinking before the build, and the craft your customers notice.
- Product strategy
- UI and UX design
- Research and prototyping
Engineering
Native apps and web products built to hold up as they grow.
- iOS and Android
- Web development
- APIs and infrastructure
AI
AI wired into products where it earns its place.
- AI integration

Launch & scale
Out the door, then better every release.

- Post-launch scaling
Where the work lives
One platform for both teams.
We run the work on a platform we built. Connect GitHub, Jira, the app stores, and your analytics, and it ranks what to fix next and scopes each item ready for your backlog.
It watches crashes, performance, and store reviews, then alerts your team in Slack. Follow along at a glance or work the tickets with us.
You always know what shipped.

Common questions
The things people ask first.
How much does it cost to build an app?
Most apps land between $25,000 and $300,000 or more, depending on scope. A focused MVP usually falls between $25,000 and $150,000. Apps on both platforms with custom backends and AI features run higher.
Every build starts with a scoped estimate before work begins. Our estimates land at 95% accuracy.
Can we bring in just one discipline?
Yes. Teams bring us in for design alone, or to add engineers to a product group they already have. Use the full team from idea to launch, or fill a single gap.
Who owns the code?
You do, from the first commit. No lock-in and no annual minimum.
How do we get started?
Tell us about your project. We will set up a call to talk through your goals, then follow up with a scoped estimate.
Do you work with startups or enterprises?
Both. We have built early MVPs for founders and shipped at scale for Nike and Realtor.com. The team flexes to the stage you are at.
Tell us what you're building.
A new product, or one you're ready to scale. Start with a conversation and we'll follow up with a scoped estimate.
Scoped estimate before build work begins. You own every line of code.
