Why Choose Garage2Global for Mobile App Development?

A straight chat, not techno‑babble

Look, I’ve seen too many decent businesses stitched up by shiny proposals and soft delivery. Last quarter a founder from Manchester turned up—£80k down, checkout failed on every third purchase. Brutal. We rebuilt the flow (Swift + Kotlin), wired Crashlytics, and within four sprints conversions climbed 37%. It’s not magic. It’s rigour and pride.

  • Strategy first: discovery, user stories, acceptance criteria, MVP scope.
  • Native and cross‑platform: Swift, Kotlin, Flutter, React Native.
  • Transparent pricing, weekly demos, no nonsense.
  • Post‑launch growth: ASO, analytics, lifecycle campaigns.

We remove the fear—rejections, delays, budget blow‑outs

Worried about App Store rejection? Tight budget? Short timeline? I get it. We manage App Store Connect/Play Console end‑to‑end, lock scope early, and show progress every Friday. You’ll always know where you stand. And yes—30‑day warranty after launch.

Client Success Stories & Case Studies

“Honestly, after the first agency blew our budget, G2G were different—tight sprints, plain English, ruthless QA. We hit 10,000 downloads in week one and doubled revenue in a month.”

5/5

I’ll admit—once, we underestimated a third‑party API rate limit on a logistics build. It stung. We paused, added a cache layer, exponential backoff, and JWT refresh. Result? 42% faster responses and 99.9% success rate. Lessons baked into our playbook.

  • Outcome: +37% conversion, −41% churn
  • Tools: Firebase Analytics, Amplitude, Segment
  • Stack: Node.js, GraphQL, MongoDB, Docker, Kubernetes

Why Mobile Apps Are Essential for Business Growth

Apps convert better. Push drives repeat visits. Offline mode saves the day on trains to London or trams in Manchester. With ASO and lifecycle messaging, we usually see 1.5–2.3x conversion over mobile web. Sources: Apple Developer, Google Play Console, Statista, Gartner, and Stack Overflow.

Let’s Talk About the Messy Bits (and How We Handle Them)

App store rejection fears

We’ve seen avoidable rejections: missing privacy labels, vague metadata, clashing permissions. We run pre‑submission checklists, sanity‑check screenshots, and stage the rollout. Does it guarantee approval? No. Does it slash risk? Absolutely.

Budget & timeline anxiety

We lock scope early, report burn weekly, and break work into sprints you can actually see. If trade‑offs appear, you see them first.

Technical complexity

No waffle. We’ll explain options in plain English, share Loom walkthroughs, and document as we go. You shouldn’t need a CS degree to make good decisions.

Post‑launch reality

OS updates, SDK changes, new devices—stuff moves. We offer SLAs, scheduled updates, and proactive monitoring so stability doesn’t slide.

Frequently Asked Questions (FAQs)

How much does mobile app development cost in the UK?
Most projects fall between £15,000 and £150,000. MVPs with core features (auth, profiles, push) land around £15k–£40k. Payments, maps, and integrations push into £40k–£80k. Complex realtime or AI features can exceed £80k. We’ll price transparently and map scope to your goals and budget.
How long does it take to develop a mobile app?
Expect 8–12 weeks for a simple MVP, and 20–32+ weeks for complex builds. We work in two‑week sprints, run weekly demos, and keep a live roadmap so you can see progress and make decisions quickly.
Do you develop both iOS and Android apps?
Yes—native (Swift/Kotlin) and cross‑platform (Flutter/React Native). We’ll recommend the best route based on performance needs, budget, timeline, and long‑term maintenance.
What’s the difference between native and cross‑platform?
Native (Swift/Kotlin) delivers top performance and UI polish. Cross‑platform (Flutter/React Native) lets you share a codebase across iOS and Android—faster to ship and cost‑effective. Many enterprise builds mix both with native modules where needed.
Will my app get approved by Apple App Store and Google Play?
We design with compliance in mind and run pre‑submission checks. We prepare metadata, privacy labels, screenshots, and age ratings. Approval is Apple/Google’s decision, but our rejection rate is very low because we follow guidelines from day one.
Do you provide app maintenance after launch?
Absolutely. We offer support plans for OS updates, dependency upgrades, monitoring, crash fixes, and minor enhancements. You’ll get SLAs and monthly stability/performance reports.
Can you help with app marketing and ASO?
Yes. We align ASO (keywords, screenshots, video) with acquisition and pair it with lifecycle messaging (push, in‑app, email). Need more? Our SEO and digital marketing teams can run campaigns for installs and revenue.
What do you need to start my project?
Goals, target users, must‑have features, budget range, timeline, stakeholders, and compliance notes. If you don’t have user stories or wireframes, we’ll create them during discovery.
Do you sign NDAs?
Yes—we’ll sign yours or provide ours. Access to your materials is limited by role‑based permissions in our toolset.
Can you integrate my app with existing systems?
We integrate with CRMs, ERPs, payment gateways, analytics, and custom APIs. We handle OAuth/JWT, webhooks, and safe data sync with attention to performance and failure modes.
What happens if I need changes during development?
We expect change. Minor items go into the next sprint; larger shifts are handled via change requests with clear cost and timeline impacts. You’ll always see trade‑offs before deciding.
Do you provide UI/UX design services?
Yes. Research, wireframes, prototypes, and high‑fidelity design in Figma, plus accessibility testing and a reusable design system.
Can you help with app store submissions?
We manage App Store Connect and Google Play Console end‑to‑end—bundle signing, screenshots, privacy labels, and staged rollouts. You keep full ownership and access.
What technologies do you use?
Mobile: Swift, Kotlin, Flutter, React Native. Backend: Node.js, Firebase, GraphQL, REST, PostgreSQL, MongoDB. DevOps: Docker, Kubernetes, CI/CD. Analytics: Firebase Analytics, GA4, Mixpanel, Amplitude.
Do you offer fixed‑price or hourly billing?
Both. Discovery is fixed. Delivery can be fixed scope or time‑and‑materials with transparent weekly reporting. We’ll recommend what fits your risk profile and roadmap.
