Push Notifications: Best Practice and Pitfalls Push notifications are messages your app can send to a user's device even when the app is closed. Used well, they bring people back and add genuine value; used badly, they are the fastest way...

App Store Optimisation (ASO) Basics Building a great app is only half the job; people have to find it. App Store Optimisation is the practice of improving your store listing so it ranks well and converts browsers into dow...

Handling App Store Review Guidelines Both Apple and Google publish detailed guidelines that every app must follow to be accepted and stay live. They cover everything from privacy and payments to content and design. We treat these g...

Progressive Web Apps vs Native Apps A Progressive Web App (PWA) is a website that behaves like an app — it can be added to the home screen, work offline and send notifications — without being downloaded from a store. It i...

App Permissions and User Trust Apps ask permission before accessing sensitive things like the camera, location or contacts. Each request is a small moment of trust — and a moment where users decide whether your app respects them. R...

Accessibility on Mobile Apps An accessible app can be used by everyone, including people who rely on screen readers, larger text, or who cannot use precise touch gestures. Accessibility is both the right thing to do and a way to reach a w...

Why Apps Get Rejected and How We Avoid It App store rejections are common and rarely catastrophic, but they cost time. Apple in particular rejects a meaningful share of first submissions, usually for predictable reasons. We design ...

App Performance and Battery Considerations A fast, smooth app feels trustworthy; a sluggish one that drains the battery gets uninstalled. Performance on mobile is about more than raw speed — it is also about being a good citizen on the us...

Background Sync and Data Refresh Users expect an app to be up to date the moment they open it, without staring at loading spinners. Background sync quietly fetches and updates data when conditions allow, so the latest inf...

Dark Mode in Mobile Apps Dark mode swaps an app's bright background for a dark one, which many users prefer for comfort in low light and to save battery on certain screens. Both iOS and Android let users set a system-wide preference your ...

Handling OS Version Fragmentation Your users are not all on the latest operating system. Some run the newest release; others are years behind, especially on Android. Supporting a sensible range of versions is a constant balancing act....

Re-Engaging Lapsed App Users Most apps lose contact with the majority of users over time. Winning back people who installed your app but drifted away is often cheaper and more effective than finding brand-new users. Re-enga...

App Icons, Splash Screens and Branding Your app icon is the first thing people see in the store and the face of your app on every home screen. Together with the splash screen and consistent in-app branding, it sets expectations before a s...

Tablet and Foldable Support Not everyone uses your app on a standard phone. Tablets offer far more screen space, and foldable devices change shape in the user's hand. An app designed only for phones can waste this space or behave oddly....

Beta Testing with TestFlight and Play Console Before your app reaches the public, it is wise to put it in front of real users in a controlled way. Apple's TestFlight and Google's Play Console testing trac...

Reducing App Size for Faster Downloads A large app is slower to download, more likely to be skipped on a mobile connection, and quicker to be deleted when storage runs low. Keeping your app lean improves install rates and retention. ...

App Analytics: Understanding How People Use Your App Once your app is live, analytics tell you what is actually happening: which features people use, where they get stuck, and what makes them come back or leave. This turns guesswork into ...

Maps and Location Features Done Right Maps, directions and location awareness can make an app genuinely useful — finding nearby stores, tracking a delivery, or recording where something happened. But location is also among the most sensit...

Data Privacy Labels and App Store Disclosures Both Apple and Google require you to declare what data your app collects and how it is used. These privacy labels appear on your store listing so users can make an informed ch...

Localisation: Shipping Your App in Multiple Languages If your audience spans more than one language or region, localisation makes your app feel native to each of them — not just translated text, but dates, currencies, for...

Offline Support: Apps That Work Without Signal Mobile devices lose connection constantly — on trains, in lifts, in rural areas. An app that simply freezes or shows an error when offline feels broken. Thoughtful offline support keeps it us...

Securing Data on a Mobile Device Phones are lost, stolen and shared. Any sensitive information your app stores or transmits must be protected so that, even if a device falls into the wrong hands, your users' data stays safe. Mobile...

Onboarding Flows That Keep New Users The first few minutes with your app decide whether a new user stays or leaves. A good onboarding flow gets people to their first valuable moment quickly, without overwhelming them....

Migrating an Old App to a Modern Codebase Apps built years ago often reach a point where they are costly to maintain, slow to change, or at risk of breaking on new devices. Migrating to a modern codebase renews the founda...

Biometric Login: Face ID and Fingerprint Biometric login lets users sign in with their face or fingerprint instead of typing a password. It is faster, feels modern, and — done correctly — is more secure than a password people tend to reus...

iOS and Android: Key Differences That Affect Cost Even when you build one app for both platforms, iOS and Android are not identical. Their design conventions, device ranges and store rules differ, and those differences feed directly into ...

Deep Linking: Sending Users Straight to Content A deep link is a link that opens your app at a specific place — a particular product, article or screen — rather than just launching the home screen. It is the glue that con...

From Idea to Launch: A Typical App Timeline Clients often ask how long an app takes and what actually happens along the way. While every project differs, most follow a recognisable path from initial idea through design and build to a publ...

Native vs Cross-Platform Apps: Which Is Right for You One of the first decisions in any app project is whether to build separate native apps for iOS and Android, or a single cross-platform codebase that t...

App Updates and Phased Rollouts Releasing an update is a moment of risk: a bug that slips through can reach every user at once. Phased rollouts let you release gradually, watching for problems before everyone gets the new...

User Feedback and In-App Ratings Prompts Ratings and reviews heavily influence whether new users trust your app, and they affect its ranking in the stores. Asking for them at the right moment — and listening to the feedback — makes a real...

Payment Integration on Mobile Taking payment inside an app can mean several things, from buying physical goods to subscribing to a service. The right approach depends on what is being sold, because the platforms have firm rules about whic...

What a Minimum Viable Product (MVP) Looks Like for Apps An MVP is the smallest version of your app that delivers real value and lets you learn from genuine users. It is not a half-built product — it is a complete, polishe...

Camera, Photos and Media in Apps Letting users take photos, record video or pick images from their library opens up powerful features — from profile pictures to document scanning. Handling media well, though, involves more than opening th...

App Store and Google Play: The Submission Process Getting your app live involves more than uploading a file. Both Apple's App Store and Google Play have a structured submission and review process, each with its own accounts, assets and ru...

Wearables and Companion App Considerations Smartwatches and other wearables let your app reach users on their wrist with glanceable information and quick actions. A companion app extends your main app onto these devices, ...

Crash Reporting and Fixing Issues Fast Even well-tested apps occasionally crash on a device or combination of conditions you never anticipated. Crash reporting tells you when, where and why — automatically and in detail —...

Designing for Different Screen Sizes and Notches Phones come in a huge variety of shapes, with different heights, widths, rounded corners, notches and camera cut-outs. An app that looks perfect on one device can look broken on another if ...

In-App Purchases and Subscriptions Explained If you plan to sell digital goods, premium features or content inside your app, you will almost certainly use the platforms' in-app purchase systems. These handle payment, but ...

App Maintenance: Why It Never Truly Ends Launching your app is the beginning, not the end. Operating systems update, devices change, libraries age and store rules shift. Without ongoing maintenance, a working app can quie...
