Flutter and React Native builds tested on real devices before they ever touch a real user. Cross-platform without the cross-platform compromise.
Users expect 60fps and instant transitions. Most cross-platform builds deliver neither. Sluggish load times, laggy scrolls, and a general feeling that something is off. Your retention numbers show it even if your dev team won't say it.
Maintaining separate iOS and Android codebases doubles your cost and halves your speed. Feature parity becomes a constant battle. One platform is always behind. Your users on the other platform notice.
Simulators are convenient. They are also liars. Your app works perfectly on an emulator and crashes on a three-year-old Samsung. If you are not testing on real hardware, you are shipping hope.
We build mobile apps that feel native because we treat cross-platform as an architecture decision, not a shortcut.
See what you get →Every mobile build includes the same core package. No features sold separately. No surprises on what is included.
iOS and Android packages compiled, signed, and ready for App Store and Play Store submission.
You own everything. Clean commit history, properly branched, with documentation your next developer can actually follow.
Every device tested, every edge case documented. Nothing ships without sign-off on real hardware.
Every endpoint, every data flow, every auth mechanism documented so your backend team stays aligned.
Know what users do, where they drop off, and when something breaks from the first session.
Bugs, store submission issues, and edge cases covered. We do not hand over a zip file and disappear.
If any of these describe you, we will tell you on the first call rather than waste your time or ours.
Founder at Seconddate
Foundry 5 really impressed me with their work on my AI-powered dating app. They nailed the UI/UX, starting with core app screens and then translating that vision to the web. The React site they built is sleek and polished - exactly what I was hoping for. What I appreciated most was their thoughtful approach and how easy they were to work with. They got the job done without needing me to micromanage.
CEO at StreaksAI
Foundry 5 surpassed all expectations in delivering our web development product swiftly and flawlessly. Their speed and eye for detail, especially under tight time constraints, showcase their commitment to excellence.
CEO, Xcelsior Capital
Working with Foundry 5 has been a great experience from start to finish. They seamlessly translated our vision into a website that not only showcases our brand and operations but also enhances our online presence as an investor in natural resources. Nothing was too much for them and they always put the client first.
CEO of Ove
Working with Foundry 5 to create the Ove app has been an absolute pleasure. Their professionalism, work ethic, and willingness to always go the extra mile has really impressed me. I would recommend them to anyone.
Loom Founder
Foundry 5 have gone above and beyond to bring my vision of Loom to life. Not only this, but they continue to be an integral part of our team. They are lovely people to work with, and I recommend them to anyone looking for a software partner. Particularly for non-technical tech founders (like me!) who need to ensure that their business is in safe hands.
Chief Product Officer Gather
The team has been instrumental in driving both the design and development of Gather, pairing a proactive, highly responsive workflow with the technical depth needed to handle our platform's complexity. Their partnership continues to move the product forward in a reliable and impactful way.

We scope the project, agree a price, and stick to it. No surprise invoices. No scope creep charges. If something changes, we talk about it before it costs you anything. You get a written scope document before code starts.
For ongoing development or projects where requirements are still being discovered. You reprioritise at the start of each sprint. Pay for what gets built, adjust as you learn.
Anything else? Just book a call. We'd rather talk than write another FAQ entry.

We build cross-platform using Flutter and React Native. Both frameworks now deliver native-level performance when implemented properly. You get iOS and Android from a single codebase without the two-team overhead. The key is architecture and that is where most agencies cut corners.
An MVP mobile app typically takes four to six weeks. A production app with deeper feature sets runs six to twelve weeks depending on complexity. We scope tightly before we start, so you always know the timeline in writing before any code is written.
Yes. We build with store guidelines in mind from the start. We have never had a client app rejected permanently. If there are review issues, we handle the resubmission and the fixes as part of the engagement.
Absolutely. We integrate with existing APIs, databases, and services. If your backend needs adjustments to support the mobile app properly, we will tell you what is needed and can handle it ourselves or work alongside your backend team.
Yes, all of the above. Push notifications, in-app payments, Stripe, social auth, maps, camera, biometrics we have built all of these multiple times. They are standard parts of our mobile builds.
Thirty days of post-launch support is included as standard. Bugs, edge cases, and store submission issues are all covered. After that, most clients move into an ongoing engagement for new features and iteration. The team that built it maintains it.
Every single build. We test on a matrix of real iOS and Android devices across screen sizes and OS versions. Emulators are useful during development, but nothing ships without real device QA sign-off.
Tell us what you want to ship. We will tell you what it takes, how long it takes, and what it costs. Honestly.
