Custom Android app
Custom code in Kotlin or Java, shaped around how your business works.
We build apps, bots and internal software from scratch, around what your business actually needs.
When a website alone isn't enough, the next step is a mobile app, a smart bot or internal software. We build it from scratch around what your business actually needs, with serious security standards, never from a template.
If your business has grown and needs a mobile app, an automated reply bot or internal software, this is the right place to start.
We build it to the same security standards as our websites, and if we built your website too, the work moves faster.
From a mobile app to a bot and custom software:
Custom code in Kotlin or Java, shaped around how your business works.
Native development in Swift for a smooth experience that follows Apple's standards.
Automatic replies, order handling and customer follow-up, around the clock.
Internal systems built with PHP, Python, Java or Swift.
Databases on MySQL or SQL Server, sized for your real workload.
For projects that need transparency and decentralization, with clear technical advice.
Native development in Swift and Kotlin gives the best performance, but it needs two separate teams and costs more. Cross-platform uses one shared codebase: faster and more affordable, with a few limits on hardware-dependent features.
Before we recommend a path, we agree on the app's goal, budget and timeline together. For content and simple forms, cross-platform is usually the sensible choice; when performance comes first, we recommend native, even at a higher cost.
We write down the app's goal, users and budget in a technical brief.
Before any code, we design the user experience and the interface.
We choose between native and cross-platform based on the project's real needs.
We build in short cycles and test performance, security and compatibility in each one.
We publish the app to store guidelines and keep supporting it after launch.
An app built from scratch to your business's real need, not a ready-made template. Security, testing and support are part of the work.
Tap any step to read the details behind it.
We write the goal, users and budget in one technical document. Fixing work that was built on guesses costs more.
Before writing any code we design the user experience and look of the app, so we agree first.
Before suggesting any route we clarify goal, budget and timing. If performance comes first, we suggest native, even at a higher cost.
From data storage to secure communication with the server, security is part of the coding, not an extra step at the end.
We build in short cycles and test performance, security and compatibility in each one. No app is handed over untested.
Updates, bug fixes and keeping up with new OS versions are part of our commitment, not a hidden cost.
Every need has its own technical path; these are the solutions we put into our plans for each.
Tap any solution to see exactly what it includes.
A first version of an idea on one platform.
Simultaneous development on both main platforms.
A mid-size app with payments and order management.
Heavy-duty features for large businesses.
Answering and taking orders at every hour of the day and night.
Internal systems, databases and projects that need transparency and decentralisation.
We put the published process of five app development teams next to Google's standards and lined our own work up against each step.
All five open with discovery; outputs include, for example, a scope document, user personas and success metrics. Attract Group warns that if a phase has no output, the next estimate is full of assumptions, and cost overruns start there.
With us We write the app's goal, users and budget into a technical brief, and never start coding without it.
All five deliver wireframes or a clickable prototype before code; Appzoro hands over a Figma prototype and a full design system.
With us Before any code, we design the experience and look of the app in Figma.
Four of the five treat architecture and stack as their own step; Appzoro settles the API, data model and security model there, before the build.
With us We choose between native and cross-platform from the project's real needs, and tell you why.
Four of the five build in sprints; Appzoro runs them at one to two weeks and demos the build at the end of each.
With us We build in short cycles and test performance, security and compatibility in each one.
All five test, and three name security explicitly. Google measures quality with numbers: crashes for over 1.09% of daily users, or ANRs over 0.47%, count as bad behaviour.
With us We do not deliver an app without security and performance testing.
All five count Google Play and App Store release as part of the job; Attract Group even lists store metadata and privacy disclosures among this phase's outputs.
With us We publish the app according to store guidelines.
All five support or improve after launch. Play judges quality over the last 28 days and flags an emerging issue after 7 days, leaving 21 days to fix it before visibility drops.
With us Updates, bug fixes and keeping up with new OS versions are part of our commitment, not a hidden cost.

Not our opinion: these are the lines Google Play draws in Android vitals, and how the leading teams work.
A user-perceived crash for more than this share of daily users counts as bad behaviour.
Android vitalsAn app not responding (ANR) beyond this line is also bad behaviour.
Android vitalsIf a single phone model passes 8%, you get flagged even with a good average.
Android vitalsGoogle judges quality over the last 28 days.
Android vitalsAn issue lasting over 7 days is flagged, and you have 21 days to fix it.
Android vitalsSprints of one to two weeks, with a demo of the build at the end of each.

The upper end of each stage, in weeks, in one team's published process. Building always takes the longest, not design.

Only what this page already promises, laid out along the same three phases the teams and the standards use.
From data storage to secure server communication, security is built into the code, not added at the end.
If we built your website, we already know your infrastructure and how your business works.
Updates, bug fixes and keeping up with new OS versions are part of our commitment, not a hidden cost.
The price depends on the number of screens, how complex the features are and the platform. After a short, free requirements session, we send you a clear quote.
Prices are in US dollars and don't move with exchange rates, so there's no need to call for the "real" price.
An initial version of an idea on a single platform.
Simultaneous development for both major platforms.
A mid-size app with payments and order management.
Heavy-duty features for larger businesses.
Simple automated replies and order-taking.
A bot with payments and CRM integration.
ERP systems, network and custom infrastructure, blockchain projects.
What is good to know before you order an app.
For moderate features, usually 4 to 8 weeks; simpler bots take less time.
Yes. Depending on your budget, we build two native apps or one cross-platform codebase; we make that call together.
An app is a standalone, installable program; a bot runs inside another platform and launches faster and cheaper.
Yes. Bug fixes and keeping up with new OS versions are part of the service.

In a free session we talk through your idea and budget, then suggest the right path.
