Technical foundations for Google: page titles, descriptions, a sitemap and clean URLs

Understanding your actual workflow before writing the first line of code

The same data is manually entered into several different systems.
Standard software does almost everything except your most important step.
You pay monthly for an application but use only a fraction of it.

Android apps

An app is worthwhile when people need to capture, look up or report information on the go. First, we check whether a mobile-friendly website already meets that need. The required functionality determines the right solution.

What you receive

Android app compatible with commonly used recent versions
An interface following Android conventions, so no training is needed
Offline use with data transferred later, where the workflow requires it
Publication on the Play Store or distribution within your organisation only
The source code and signing keys are yours

Scope and price

Scope	Price range
An app with a clear purposea few screens, one use case	€3,500 to €8,000

Maintenance & store upkeepongoing, cancellable at any time	from €45 / month

Time frame: 4 to 12 weeks

Indicative prices; no VAT charged under section 19 UStG.

When an Android app is right for your task

Your staff record data on paper while out and type it up in the evening.
Customers or members need to report, book or look something up.
You need the camera, location or a barcode scanner directly within the workflow.
The app should work even when there is no signal in the basement.

Scope boundaries and technology

What is not included

No iPhone version; for that, I work with someone else or you commission it separately
No games or 3D applications
No apps whose business model relies on advertising networks and user tracking

Linux server setup: web, mail, databases, certificates
Backups that have been tested, not just configured
Monitoring with notifications before the customer calls
Documentation that enables someone else to continue the work

When server software is right for your task

Two systems in your business do not communicate, but urgently need to.
A report is assembled manually every month.
You need an integration to give a service provider controlled access to your data.
Your server is running, but nobody knows whether the backups actually work.

Scope boundaries and technology

No management of large clusters or Kubernetes environments
No availability commitments that I cannot meet on my own
