Executives and business leads turning customer touchpoints into an app, and IT managers mobilizing field operations
Native and cross-platform iOS/Android apps — from customer-facing apps to field operations tools, covering store submission through offline support
Customer touchpoints — membership, booking, e-commerce, community — and field operations — inspections, sales, fieldwork — increasingly run on a phone. Once you need what the web can't deliver on its own — push notifications, offline operation, camera or sensor access — a mobile app becomes the right tool. Yakumo handles technology selection between native and cross-platform, store submission, push notifications, offline support, existing system integration, and AI integration as one engagement.

- Build a membership, booking, or e-commerce app
- Turn field inspections or sales activity into an app
- Need an app that works on both iOS and Android

- Add AI features to an app

What We Solve
What we solve
Whether it’s a customer touchpoint — membership, booking, e-commerce, community — or a field operation — inspections, sales, fieldwork — the smartphone has become the primary surface. Once you need what the web alone can’t deliver — push notifications, offline operation, camera or sensor integration — a mobile app becomes the right tool.
This service covers native and cross-platform technology selection through store submission, push notifications, offline support, existing system integration, and AI integration. We build both customer-facing apps and field operations tools.
Not “build and ship” — keeping the app running through OS updates is part of the scope.
After State
A mobile app is live in the App Store and Google Play, with feature updates and OS compatibility maintained on an ongoing basis.
Phases & Deliverables
Requirements definition
Determine whether the app is customer-facing or a field-operations tool, and decide on native vs. cross-platform and target OS.
Design
Screen design, data and API design, and non-functional requirements such as offline support and push notifications.
Implementation
Build the app through sprint-based development, including existing system integration and AI features.
Store submission and launch
App Store / Google Play submission, QA, and migration from an existing app.
Operations support
OS update support, early operational support, and feature revisions.
