DEVELOPMENT PROCESS
Our Mobile App Development Process
Every stage has exit criteria, a QA gate and a named owner — the reason our releases do not slip.
Discovery
We pull apart the idea before writing a line of code: user interviews, competitor teardown, and a ruthless cut of everything that is not the core loop.
✓ Product brief and success metrics
✓ Prioritised feature backlog
✓ Technical feasibility spike
GATE CRITERIA
Requirements signed off 100%
Risks logged 12
Scope locked Yes
UI / UX
Design thinking, wireframes, then a clickable prototype real users can hold — validated before engineering commits a sprint. WCAG 2.2 AA is a requirement, not a nice-to-have.
✓ Clickable prototype
✓ Design system and tokens
✓ Accessibility annotations
GATE CRITERIA
Usability test pass 9/10
Contrast AA 100%
Components documented 64
Architecture
Platform choice, data model, offline strategy, security threat model and the CI/CD pipeline are all decided and written down before sprint one.
✓ Architecture decision records
✓ Threat model and data flow
✓ CI/CD pipeline live
GATE CRITERIA
ADRs approved 8
Threat model Signed
Pipeline green Yes
Development
Two-week sprints, trunk-based development, a demo every Friday. Memory and battery budgets are set on day one and enforced by CI, not by hope.
✓ Fortnightly production builds
✓ Instrumented analytics
✓ Code review on every merge
GATE CRITERIA
Sprint velocity held 94%
Bundle budget Under
Review coverage 100%
QA
Our testing heritage is the unfair advantage. Automated regression across a real-device matrix, plus performance, security and accessibility passes before any release candidate.
✓ Automated regression suite
✓ Real-device compatibility report
✓ Security and performance audit
GATE CRITERIA
Automated coverage 86%
Blocker defects 0
Devices verified 180+
Deployment
Store submission, staged rollout and a live dashboard from the first install. If a metric moves the wrong way, we roll back before your users notice.
✓ Store listing and assets
✓ Staged rollout plan
✓ Crash and performance monitoring
GATE CRITERIA
Store approval 1st pass
Rollout health Green
Rollback tested Yes
Maintenance
Post-launch is where apps are actually won. We watch retention, trim memory, tune battery, keep pace with OS releases and ship the next increment on a predictable cadence.
✓ Monthly performance review
✓ Retention and funnel insights
✓ Roadmap for the next quarter
GATE CRITERIA
Crash-free sessions 99.9%
D30 retention lift +22%
Release cadence 2 wks
UI / UX
Mobile App UI/UX Design
Interfaces are validated with real users before a sprint is committed. Every screen ships WCAG 2.2 AA, responsive from a 4.7" phone to a 13" tablet.
01
Design thinking
Jobs-to-be-done workshops that decide what not to build.
02
Wireframes
Low-fidelity flows agreed before a single pixel is polished.
03
Prototyping
Clickable builds tested with real users, iterated in days.
04
Design system
Tokens and components handed to engineering, not screenshots.
05
Accessibility
WCAG 2.2 AA, dynamic type, VoiceOver and TalkBack verified.
06
Responsive by default
Phone, foldable, tablet and large-screen layouts from one system.

Client Testimonials
★★★★★
They found defects our previous vendor shipped for two years. The rewrite went live with zero P1 issues in the first month.
★★★★★
The discovery phase alone paid for itself — half the features we had planned turned out to be unnecessary, and they told us so.
★★★★★
Predictable sprints, honest status reports, and an offline sync layer that finally works in the field. Rare combination.

FAQS
Mobile App Development FAQs
A focused MVP typically lands between $25k and $60k, a full cross-platform product between $60k and $150k, and enterprise programmes are scoped per module. You receive a fixed written estimate after discovery — nothing is open-ended.
An MVP is usually 10 to 14 weeks end to end: 1–2 weeks discovery, 2–3 weeks UI/UX, 6–12 weeks build with QA running in parallel, then a week for store submission and staged rollout.
Flutter suits pixel-consistent, animation-heavy products. React Native suits teams with existing React talent and fast iteration. Native is right for deep OS integration, heavy media, or strict performance and security budgets. We recommend after the feasibility spike, not before.
Yes — an NDA can be signed before the first call, and all discovery material stays in your own workspace if you prefer.
You do. Full source, repositories, pipelines, design files and store accounts are transferred to you at handover, with no lock-in to Codoid tooling.
Yes. Codoid is a Chennai-based mobile app development company serving clients across 14 countries, with delivery models built around time-zone-friendly communication, NDA-first engagement, and fixed-cost or dedicated-team options for teams outside India.
