Overview

What this engagement is

Mobile work fails on the unglamorous parts: offline behaviour, push reliability, store review, release management. Cyntra builds mobile products with those concerns designed in from the start, using a shared API layer so your web and mobile surfaces never drift apart.

Business problems this solves

  • Field or driver teams working on paper because no mobile tool exists
  • Customers expecting a mobile experience competitors already provide
  • Existing app abandoned by a previous vendor and unmaintainable
  • Poor connectivity at the point of work breaking web-only tools
  • No controlled release process for app updates

What is included

Platform strategy (native vs cross-platform) with rationale
UX design against platform interaction guidelines
Cross-platform or native implementation
Offline-first data layer with conflict resolution
Push notification infrastructure
App Store and Play Store submission and review support
Crash reporting and release analytics

Deliverables

Questions about this service

Native or cross-platform?
We recommend based on your requirements. Cross-platform suits most business applications; we go native where heavy device integration, background processing or graphics performance demand it.
Do you handle store submission?
Yes, including account setup, listing assets, review responses and staged rollout configuration.

Eliminating 62% of inbound status calls for a regional carrier

Regional freight carrier, 90 vehicles

Challenge

Dispatch was planned on spreadsheets with no live status. Customer service handled roughly 340 "where is my load?" calls per week that staff often could not answer. Proof of delivery arrived on paper days later, delaying invoicing by an average of five days.

Cutting variation disputes 70% for a commercial contractor

Commercial construction contractor

Challenge

Daily site reports were captured on paper and frequently lost. Variations were agreed verbally and disputed at claim time, with roughly $600,000 in annual variation value written off. Subcontractor insurance certificates expired unnoticed, and cost-to-complete was only visible after month-end.

Client experience

From clients who bought this

“The driver app works without signal, which every previous vendor told us was impractical. Our POD capture rate is 99%.”

Challenge: 340 weekly status calls staff could not answer

“Photo evidence on an approved variation ends the argument before it starts. That change alone recovered more than the project cost.”

Challenge: $600K annual variation value written off through weak evidence
