Lessons learned from projects — stack, architecture, IT business.
How much does mobile app maintenance cost — in-house developer, freelancer or a block of hours
How much does mobile app maintenance cost? We break the cost down into fixed fees and work, show how many hours a month typical apps need, and compare an in-house developer, a freelancer and a block of hours at a software house.
App rejected by the App Store or Google Play — what to do, step by step
App rejected by the App Store or Google Play? How to read the reason, what to fix in the first hour, how to reply to the reviewer, when to appeal and how to reduce the risk with the next release.
Mobile app release automation — CI/CD and fastlane: what it costs and when it pays off
A manual Android and iOS release takes 3–5 hours of work and one person who knows how to do it. What you can automate with fastlane and CI/CD, what the setup costs, when it pays off and where to start.
Taking over a project from another software house — handover checklist
Code is the easiest part of a handover. What actually blocks you is copyright, ownership of app store accounts and signing keys. Here is the checklist worth working through before you sign the acceptance protocol.
Technical debt — when to pay it down and when to live with it
Not every mess is debt, and not all debt needs repaying. Four types of technical debt, metrics for measuring the interest, four repayment strategies and a list of things worth leaving alone on purpose.
Refactor or rewrite from scratch — how to make the call on numbers, not gut feeling
A rewrite is tempting because it promises a clean slate — and it gets priced as if a clean slate were free. We show the real cost of rewriting, five questions that settle the decision, and the strangler pattern as a third way.
Source code audit — what it covers, how long it takes and when it's really worth it
A source code audit isn't a verdict on your developers — it's a risk assessment. We show what we check across six areas, how a code quality audit works, what the report contains, what it costs and when an audit isn't worth it.
Your app disappeared from Google Play for new users? You haven't been banned — the API 36 deadline has passed
The Google Play deadline passed on 31 August 2026: updates must target Android 16 (API 36), and existing apps must target API 35 to stay available to new users. What exactly happened, how to check your targetSdk and how to request an extension to 1 November.
Will your app survive 2027? A 15-point checklist you can run yourself
A 15-point checklist you can work through yourself in a single afternoon: targetSdk, library versions, vulnerabilities, crash rate, ANR, build time, tests, store account ownership and signing keys. Includes scoring and the order to fix things in.
