Hire a Dedicated Mobile Development Team
A dedicated mobile development team is a full pod that runs iOS and Android as one program: one release train, one device lab, one store compliance owner, and one accountable squad for your mobile roadmap.
Siblings Software assembles these pods for product teams where the app is the primary customer surface. Typical buyers are CTOs, VP Engineering, and product leaders who need sustained ownership across Swift, Kotlin, React Native or Flutter, Fastlane release pipelines, App Store and Play Console governance, and QA on a real device matrix. Monthly retainers run USD 18,000 to 48,000 depending on pod size, inside the broader dedicated development team band of USD 12,000 to 60,000. This page covers when a mobile pod fits, standard team composition, the first 30 days, governance, quality standards, pricing, an example engagement, risks, and FAQs. If you only need one or two engineers inside an existing squad, see mobile staff augmentation. If Windows or desktop is part of the same product, start at the app development team umbrella page instead.

When a dedicated mobile development team makes sense
A mobile pod fits a specific set of situations more than a generic request for more developers:
- iOS and Android are most of the product. Web is marketing or light companion traffic, and both stores need to ship on the same cadence.
- Release mechanics are the bottleneck. Store rejections, Privacy Manifest work, Play data safety forms, or a broken Fastlane pipeline are blocking feature delivery.
- The roadmap spans multiple quarters with shared design tokens, native modules, and crash budgets that need one owner across both platforms.
- Your internal team is strong on backend or web but nobody owns mobile release governance, device lab coverage, or store compliance full time.
If you already run sprint ceremonies and only need extra senior hands, mobile staff augmentation is usually faster to start. If the scope is a bounded launch or compliance sprint, project-based outsourcing may fit before a long-running pod. For the service-level view across mobile delivery models, see mobile app development outsourcing.
The Mobile Pod Fit Test
Before a discovery call, run these three questions internally. Three yes answers usually mean this mobile pod page is the right shape. Any no means we route you to staff augmentation, the umbrella app team, or a single-platform sibling with reasons on the call.
Q1. Surface share
Are iOS and Android together at least 85 percent of how customers reach the product?
Q2. Desktop absent
Is there no Windows tablet, .NET MAUI desktop, or back-office surface that needs its own engineering track?
Q3. Parity cost
Does the roadmap punish feature parity gaps between the two stores within a sprint?
Platform-specific depth lives on the iOS, Android, and cross-platform sibling pages when you have already chosen one stack lead.
Standard team composition
The default mobile pod is six seats sized for iOS and Android on one release train:
Mobile tech lead. Owns the platform call, architecture decision records, rejection runbook, crash budget gate, and release readiness sign-off on both stores.
Swift and Kotlin specialists. Own HealthKit, BLE, secure enclave, foreground services, Wear OS, and native surfaces that cross-platform layers cannot cover honestly.
Cross-platform engineer. Carries React Native or Flutter parent navigation, shared state, design system, and deeplink graph when that is the agreed parent stack.
QA automation engineer plus fractional mobile DevOps. Runs the device matrix, regression suite, Fastlane lanes, signing, and staged rollout policy on App Store Connect and Play Console.
Lean pod (4 to 5 people)
Tech lead, two mobile engineers, shared QA, fractional mobile DevOps. USD 18K to 26K per month.
Standard pod (6 people)
Full composition above. USD 22K to 38K per month. Most mobile programs use this shape.
Heavy pod (7 to 8 people)
Extra native depth or designer seat. USD 38K to 48K per month.
Framework-specific pods are available through our React Native development team, Flutter development team, Swift development team, and Kotlin development team pages when the stack choice is already fixed.
Your first 30 days
Days 1 to 5
Discovery, repo and CI read, analytics-based device matrix proposal, and a written platform decision memo.
Days 6 to 12
Team assembly, Apple Developer and Play Console access, signing handoff, and sprint zero goals agreed.
Days 13 to 21
Sprint zero: CI green on the device matrix, Fastlane lanes merged, privacy YAML drafted, rejection runbook written.
Days 22 to 30
First TestFlight and Play internal testing build, sprint one delivery against an agreed goal, weekly demo and retro.
External references we use in sprint zero include the Apple App Store Review Guidelines, Android developer documentation, and Fastlane documentation.
Governance and communication
Your product owner owns priorities. Our delivery lead runs sprint planning, standups, and stakeholder updates. The mobile tech lead owns architecture decisions, code review service levels, and production readiness sign-off on both stores.
Apple Developer Program membership, Play Console access, distribution certificates, provisioning profiles, and upload keys stay under your organization throughout the engagement. Our engineers join as members of your developer teams. Escalation path: engineer to tech lead to delivery lead to your engineering director within one business day. Source code, CI configuration, and store metadata live in your repositories from day one.
Quality standards
Definition of Done on a mobile pod includes peer review, regression tests on the agreed device matrix, updated privacy nutrition label and Play data safety form generated from shared YAML, a rollback build on the release branch, and release notes drafted before submission.
Typical gates we agree in discovery: crash-free sessions above 99.5 percent on the latest two releases, ANR rate under 0.5 percent on Play, and cold-start budget measured on the lowest-end Android device that produces meaningful session share. For security-sensitive apps we align practices with the OWASP Mobile Application Security Verification Standard.
Pricing model
Dedicated mobile pods bill monthly within the USD 12,000 to 60,000 company band. The main cost drivers are pod size, native module depth, and how much store compliance or platform migration work the first quarter requires:
Lean pod
USD 18K to 26K / month
Four to five seats. Fits ATT rebuilds, watch surfaces, or a single-quarter modernisation alongside a healthy internal mobile lead.
Standard pod
USD 22K to 38K / month
Six seats with full release train, device lab, and on-call coverage through major release windows.
Heavy pod
USD 38K to 48K / month
Seven to eight seats for fintech, healthcare, or IoT companion apps with deep native work on both platforms.
Every tier includes a two-week satisfaction guarantee. Scaling down requires 30 days notice after the initial period. For a single specialist embedded in your rituals, mobile staff augmentation typically runs USD 4,000 to 9,500 per month per engineer.
Dedicated mobile team, staff augmentation, freelancers, or in-house
Dedicated mobile team (this page). One pod owns iOS and Android on one cadence with QA and mobile DevOps included. Fits multi-quarter mobile roadmaps.
Staff augmentation. One or two senior mobile engineers under your engineering manager. Fits when ceremonies and release ownership already exist internally.
Freelancers or marketplaces. Fast to start for small fixes. Risky for store compliance programs, device lab coverage, or multi-quarter parity work without a delivery lead.
In-house hiring. Best long-term ownership, but sourcing senior Swift and Kotlin engineers in US metros often takes several months per seat. Many teams run a pod while hiring catches up.
Risks and how we reduce them
- Store rejection delays. Sprint zero ships the rejection runbook, privacy YAML, and data safety form before feature work competes for the same sprint.
- Platform drift between iOS and Android. One release train, one Fastlane configuration, and a tech lead with veto authority on parity exceptions.
- Performance regression on low-end Android. Device matrix includes the lowest-end handset that produces meaningful traffic, measured on every release candidate.
- Handoff risk if the engagement ends. Source code, CI, store metadata, and runbooks live in your repositories from day one.
Example engagement
Illustrative scenario based on a composite US consumer insurance mobile program. Names and figures are representative, not a published client case study.
Ridgeview Personal Insurance (composite) runs a direct-to-consumer auto and home app where most policyholder interactions happen on mobile: digital ID cards, photo-based first notice of loss, telematics hardware pairing, and renewal push. Crash rates had slipped, store ratings dropped, and cascading App Store and Play rejections blocked a marketing launch.
A six-seat Siblings mobile pod joined alongside one internal engineer: tech lead, Swift specialist, Kotlin specialist, React Native engineer on the parent app, QA with device lab, and fractional mobile DevOps. Sprint zero produced the rejection runbook, device matrix from analytics, Privacy Manifest YAML, and a Fastlane pipeline the whole team could run. Over the next sprints the pod stabilised crash rates, cleared privacy-related resubmissions, rebuilt a BLE telematics bridge, and restored a weekly release train on both stores. Engagement cost was in the low USD 30Ks per month for the six-seat pod.

Frequently Asked Questions
Run the Mobile Pod Fit Test during discovery. When iOS and Android are most of the product surface, you need one release train on both stores, and nobody on your side owns store compliance full time, a pod with a tech lead, QA, and mobile DevOps usually fits better than adding one or two contractors. If you already run sprint ceremonies and only need senior hands, mobile staff augmentation is typically faster to start.
Three questions: whether iOS and Android are at least 85 percent of customer reach, whether there is no separate Windows or desktop track, and whether the roadmap punishes store parity gaps within a sprint. Three yes answers point to this mobile pod. A no on desktop routing points to the umbrella app development team page instead.
Lean pods run USD 18,000 to 26,000 per month. The standard six-seat pod runs USD 22,000 to 38,000 per month. Heavy pods run USD 38,000 to 48,000 per month. All tiers include a two-week satisfaction guarantee inside the USD 12,000 to 60,000 dedicated-team band.
You retain account ownership. Our engineers join as members of your developer teams and operate release pipelines, reviewer notes, and staged rollouts from your repositories.
Discovery takes three to five days, team assembly runs five to ten days, and sprint zero completes in weeks two and three. Most pods ship a TestFlight and Play internal testing build by week four.
Your product owner sets priorities. Our mobile tech lead owns architecture and release readiness. The delivery lead runs ceremonies and weekly reporting.
Adding seats usually takes one to two weeks. Scaling down requires 30 days notice after the initial period. Many pods start as two engineers through mobile staff augmentation and convert once release ownership becomes the bottleneck.
OUR STANDARDS
A written rejection runbook beats a midnight Slack thread when App Review emails land.
Every mobile pod engagement ships with a device matrix cut from your analytics, weekly internal builds on TestFlight and Play internal testing, and honest reporting on the crash and release metrics agreed in discovery.
