Notes worth keeping.

Writing a useful app brief

A good brief describes problems, not features. Include who the users are, what they struggle with today, how you will know the project worked, any deadlines that genuinely cannot move, and what systems the app must connect to. One page is plenty. Leave the technology choice open unless you have a firm reason.

Native or cross-platform?

Cross-platform toolkits let one team ship to iOS and Android from a shared codebase, which often reduces maintenance costs. Native builds can make sense for intensive graphics, deep hardware integration or when you only target one platform. The right answer depends on your users and budget, not on fashion.

Accessibility basics for apps

• Every control needs a label that a screen reader can announce.
• Support system text sizes and avoid fixed-height text containers.
• Do not rely on colour alone to convey meaning.
• Touch targets of around 44 by 44 points are easier for everyone.
• Test with VoiceOver and TalkBack before launch, not after.

Store privacy declarations, demystified

Apple asks for privacy "nutrition labels" and Google Play asks for a Data safety form. Both require you to declare what data the app and any third-party libraries collect. Audit your analytics, crash reporting and advertising SDKs carefully; their collection counts as yours.

Budgeting for life after launch

As a rough planning habit, set aside an annual amount for maintenance from the start. Operating system releases, library updates and store policy changes will arrive whether or not you plan new features. We are happy to talk through a realistic figure for your app.

Glossary

MVP

The smallest version that tests whether the product is worth building further.

TestFlight / internal testing

Apple and Google channels for sharing pre-release builds with testers.

Staged rollout

Releasing an update to a percentage of users first to catch problems early.
