[ SYSAIQ—SERVICE / MOBILE-APP ]

Mobile app (PWA)

An app that installs on the phone without an app store, works offline, and stays up to date on Android and iOS from one codebase.

Start a project

Who this is for

Businesses that want customers or staff to reach their system from a phone, without the hassle of app-store publishing.
Salons, clinics and restaurants that want booking, appointments or ordering on the customer's phone.
Field teams (sales, distribution, inspection) that must record data on site, sometimes without connectivity.
Owners of a web application who want the same system offered as an installable app.

Problems it solves

Slow, costly store publishing: a PWA installs straight from the browser and every update reaches everyone immediately.
Two separate codebases for Android and iOS: one codebase, one team, one maintenance cost.
No connectivity on site: data is stored offline and synced once connected.
Poor mobile experience: the interface is designed from the start for touch, small screens and one-handed use.
Users out of the loop: notifications (on platforms that support them) and SMS keep people informed.

Deliverables

Installable PWA for Android and iOS with icon, splash screen and full-screen mode
Offline operation for the agreed sections and sync once back online
A custom back end and API, or connection to your existing system
User authentication (SMS or password) and permission levels
Admin panel for content, users and app data
Deployment on your server with HTTPS and an install guide for users
Full source code, documentation and every credential handed over in your name

How the work runs

01
Discovery
We define the app's users, what must happen on the phone, the need for offline mode and device features (camera, location), and confirm a PWA fits the requirement.
02
Written proposal
You receive the app's screens and features, back end, delivery milestones, schedule and cost in writing.
03
Contract
The contract is signed in person in Qazvin or electronically; work starts after signature and deposit.
04
Staged build
You install the test build on your own phone and try it with real data; each stage closes after your approval.
05
Handover and training
The app is published on your domain, an install guide is prepared for users, and you are trained on the panel.
06
Support
Bugs are fixed free of charge during the warranty period; later versions are built under a separate agreement.

Timeline

Duration depends on the number of screens and user flows, the need for offline mode and sync, building a new back end versus connecting to an existing system, and device features (camera, location, notifications). Offline mode and sync usually take the largest share of the time.

The milestone schedule is stated in the written proposal.

How cost is calculated

Cost is calculated from:

The number of screens and user flows
Offline mode and data sync
A new back end versus connection to an existing system
Authentication, roles and notifications
Device features: camera, location, barcode scanning
The level of support after handover

Included: interface design, development, back end, deployment, install guide, training and the bug-fix warranty.

Not included, paid separately in your name: server, domain, SMS credit, notification or map services where used.

The final figure is stated only in the written proposal.

Frequently asked questions

A PWA is a web application the browser installs on the phone like an app: a home-screen icon, full-screen launch, offline use. The main difference is that it is not downloaded from a store and updates instantly. For most business uses this is enough.

Yes. On iOS it installs through Safari. Some features, such as notifications, have limitations on iOS; discovery states clearly what is and is not possible.

Discovery establishes whether a PWA meets your need or another route is required, and we say plainly what we deliver ourselves and what falls outside this service.

The sections defined as offline in the proposal, such as filling forms or viewing saved lists. Data is kept on the phone and synced with the server once connected.

If you own the code, usually yes. We review the current structure and state what changes are needed for install, offline use and the mobile experience.
