Overview
Mobile development is what we've shipped most: 14+ production apps for clients including Arby's, Buffalo Wild Wings, ADT, Medela, and Surfboard Central — across iOS, Android, and cross-platform stacks. Our mobile developers know that an App Store rejection isn't a build error: it's a UX decision, an icon size, a privacy disclosure, an in-app purchase flow that doesn't quite match Apple's guidance. They know to test on a real device before committing, what offline-first really means for sync, and why your push notifications stopped delivering after iOS 17. Hire them for the part of mobile that's not about writing the app — the part about getting it into users' hands and keeping it there.
Why Techyor.
Senior. Specialist. Shipping.
14+ shipped apps in production
Real Play Store and App Store releases — including iOS in-app purchases, Android billing, push notifications via APNs and FCM, and silent OTA updates.
Native + cross-platform, both fluent
We know when to choose React Native (most apps), Flutter (UI-heavy consumer apps), or full native (high-performance, hardware-integrated). We pick by problem, not preference.
Store launch, not just code
App Store Connect, TestFlight, Play Console, internal testing tracks, phased rollouts, ASO basics — we ship the launch, not just the build.

How you can hire.
Three ways to engage.
Dedicated Full-Time
A senior developer working exclusively on your product, embedded into your team, sprint cycle, and rituals. Best for roadmap-driven work with continuous shipping.
Part-Time / Fractional
Two to three days a week of senior expertise. Ideal for early-stage teams, technical advisory, code review, or supplementing an existing in-house team.
Fixed-Scope Project
Defined milestones, outcomes, and timeline. Best when the brief is clear and you want a predictable budget. Includes design, QA, and handover.

FAQ.
Common questions.
Native or cross-platform — which should we choose?
Cross-platform for most product apps in 2026. Choose native when you need: heavy hardware integration (camera/sensor-heavy), best-in-class UI animations beyond what React Native handles, or your team can hire two specialists and you ship to both stores at the same quality.
Can you ship to both App Store and Play Store?
Yes — full launch service including App Store Connect setup, Play Console setup, screenshots, store listing copy, privacy disclosures, and walkthroughs of the review process.
How do you handle App Store rejections?
We anticipate the common rejection patterns (sign-in with Apple, IAP for digital goods, privacy policy URLs, demo accounts for review). When a rejection happens, we read the actual review note carefully — most are fixable in a day with the right interpretation.
Do you build with Expo or bare React Native?
Expo for most projects (managed workflow, EAS Build, OTA updates). Bare RN when we need a native module Expo doesn't support, or when the app is large enough to justify the build complexity.
What about iPad and tablet support?
We ship universal apps when the product justifies it. Tablet is rarely a copy-paste of phone — we treat it as a separate UX surface and design accordingly.
Push notifications, deep links, and analytics — included?
Yes, included as standard. Default stack: Firebase Cloud Messaging, branch.io or universal links, and an analytics provider of your choice (PostHog, Amplitude, Mixpanel).
How fast can a developer start?
For most roles, within 5–10 business days from the intro call. We pre-qualify our bench so onboarding is contracts and access — not a hiring search.
Do you sign NDAs and IP assignment agreements?
Yes — every engagement starts with a mutual NDA and a clean IP assignment clause. All work product is your property the moment it's written.
What time zones do your developers cover?
Our team primarily operates in IST with 4–6 hours of overlap with US Pacific, full overlap with EU, and full overlap with AU East. We commit to overlap windows in writing.
