  • Translate business goals into a validated mobile product scope

  • Define platform strategy: iOS, Android, or cross-platform

  • Identify technical constraints, risks, and dependencies early

  • Align mobile architecture with backend and product roadmap

  • Deliver a clear execution plan with cost, timeline, and release milestones

Types of apps we develop

We build native iOS applications tailored to business-critical use cases, with a focus on performance, security, and long-term maintainability across Apple devices.
We develop native Android applications designed to meet platform-specific requirements while delivering stability, scalability, and a consistent user experience.
We create cross-platform mobile applications using React Native and Flutter when shared codebases make sense without compromising performance or maintainability.
We develop progressive web applications as a pragmatic alternative to native apps, providing fast load times, offline support, and reliable performance.
We build enterprise mobile applications that support internal operations, data security, and system integrations, designed for long-term ownership and scale.

Delivery
principles & operating model

Devico operates with defined constraints and measurable delivery rules. This is how we keep custom mobile applications development stable beyond the first release.

Delivery & planning constraints

Delivery & planning constraints

Mobile delivery is planned around release cycles, store requirements, and device variability.

  • Discovery duration: 2–4 weeks before development starts

  • Roadmap accuracy: delivery estimates typically remain within ±10–15%

  • Sprint structure: fixed sprint cadence with locked scope per sprint

  • Change handling: scope changes assessed upfront, not absorbed silently

  • Release planning: explicit planning for App Store and Google Play submission cycles

Mobile architecture & engineering rules

Mobile architecture & engineering rules

Mobile systems are engineered for longevity, not short-term velocity.

  • Architecture-first delivery: no mobile feature built without an approved system design

  • Minimum lifespan target: mobile apps designed to evolve for 3–7 years

  • Separation of concerns: mobile client, backend, and integrations owned independently

  • Platform-aware design: iOS and Android constraints addressed explicitly

  • No framework lock-in: native or cross-platform choices validated against long-term maintainability

Quality & risk control

Quality & risk control

Quality is enforced continuously across devices, OS versions, and releases.

  • Quality embedded from sprint 1, not post-MVP

  • Regression coverage grows continuously, release over release

  • Real-device testing across OS versions and form factors

  • Release readiness checks before every App Store and Google Play submission

  • Security reviews for apps handling sensitive or regulated data

Team & engagement model

Team & engagement model

Mobile delivery requires stable ownership and fast technical decisions.

  • Typical team size: 3–12 specialists, depending on mobile product complexity

  • Dedicated ownership: no shared or rotating teams mid-project

  • Direct access to mobile tech leads not account-only communication

  • Engagement models: full-cycle mobile delivery, dedicated teams, or targeted augmentation

Operational reality

Operational reality

Built for continuity, handover, and long-term ownership.

  • Onboarding time: 2–3 weeks from contract to active mobile delivery

  • Documentation is mandatory: architecture, mobile flows, platform decisions

  • Release process documented: build, signing, and store submission workflows

  • Handover-ready by default: internal teams can take over without rework
