Mobile App Solutions — Strateji Grup

On the mobile side, what determines whether an app is usable in the field usually isn't screen design. What happens when the connection drops, when data gets synced, and which device wins when two of them change the same record at once — those are what really decide it.

Which platform and which technology to build with is determined by the use case. A field app that needs deep access to device hardware and an app that mainly displays data don't have the same right answer.

Apps that treat a connection as a precondition stop being usable in the field before long.

Are we the right fit?

A mobile app isn't the answer to every need. If the user is sitting at a desk and the work runs fine in a browser, a separate app just adds maintenance and release overhead without bringing anything back for it.

Yes, let's talk

The work happens in the field, on your feet, and often with one hand
Access to device hardware like the camera, location, barcode scanner, or NFC is needed
Records need to be entered even where there's no connection

No, someone else does this better

The app would just shrink down an existing web interface
User count and usage frequency don't justify the app-store and release overhead
The real need is reporting — that's usually solved more cheaply on the web side

What we do

Platform and technology selection based on the use case
Offline operation and local data storage
Data synchronization and conflict resolution
Server-side API design

Device hardware access — camera, location, barcode, NFC, Bluetooth
Push notification infrastructure
Usability design for field conditions
App-store release processes and version management

How we proceed

01

Use cases

We work out where the app will be used, under what conditions, and how often. Field conditions determine most interface decisions from the start.

02

Data flow design

This is where we decide what data stays on the device, when it syncs, and how conflicts get resolved.

03

API contract

We write the server-side interface before app development begins. That way the two sides move forward in parallel.

04

Development and field testing

We test the app on real devices, under real usage conditions. We don't consider emulator testing sufficient on its own.

05

Release and versioning

We handle the app-store processes and set the version policy together with you. We keep older versions compatible with the server for a transition period.

The app is designed to work meaningfully even with no network connection. Field staff can enter records somewhere with no connectivity, and the data syncs once a connection is available. Apps that treat a connection as a precondition stop being usable in the field before long.
What happens when two devices change the same record is decided at the design stage. When that rule gets added later, some of the data accumulated up to that point has already become inconsistent.
Not every user updates the app at the same time. The server interface is developed to keep older versions working; otherwise, users who haven't updated get left outside the system.
Location tracking, background sync, and notification frequency are all tuned with battery life in mind. An app that drains the battery fast gets switched off by the user even if it's technically working correctly.
