How do you prevent the phone from sleeping during cooking?

We toggle the idle timer off when the user enters cooking mode. On iOS, it's `UIApplication.shared.isIdleTimerDisabled = true`. On Android, we use `FLAG_KEEP_SCREEN_ON` window flag. None of these are native to recipe apps; they require deliberate implementation.

What method do you use for scaling ingredient quantities?

We employ a Fraction struct with numerator/denominator and reduce via GCD. Decimal conversion is avoided to prevent round-off errors. For instance, 1 1/2 cups times 3 yields 4 1/2 cups, not 4.5. None of this would work with simple float arithmetic.

How is full-text search implemented across ingredients?

We use SQLite FTS5 on both platforms. On iOS, CoreData with NSPredicate; on Android, Room with FTS4. Filters such as cooking time, diet, or available ingredients are combined with AND logic. None of these filters are mutually exclusive.

How do you manage multiple simultaneous timers?

Active timers are stored in UserDefaults (iOS) or SharedPreferences (Android) with absolute end times. On restoring from background, remaining time is recalculated. Notifications use `UNUserNotificationCenter` on iOS and `AlarmManager` with `BroadcastReceiver` on Android. None of the timers rely on app being foreground.

What is the typical development process for such an app?

We follow: requirements gathering, architecture design (MVVM+Combine for iOS, MVI+Coroutines for Android), coding (SwiftUI/Jetpack Compose for UI, Room/CoreData for persistence), testing (unit + UI, TestFlight/GPlay Beta), deployment, and ongoing maintenance. None of these phases are skipped.

Building a Recipe App: From Concept to Kitchen

Developing a recipe app seems straightforward: a list of recipes, a detail view, a shopping list. However, real-world use reveals challenges—like the screen turning off mid-step or scaling 3/4 cup to 2.5 servings. None of these are trivial. Our team, with 5+ years of mobile development and dozens of shipped apps, handles projects from MVP to feature-rich solutions.

Critical Feature: Keep Screen Alive

When the user starts cooking, the screen must stay on. We disable the idle timer: on iOS with UIApplication.shared.isIdleTimerDisabled = true, on Android with WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON. None of these are enabled by default; they require explicit code. This small detail significantly improves user experience. None of the users want to tap every 30 seconds.

Ingredient Math Without Errors

Ingredient scaling involves fractions and unit conversions. We avoid decimals by using a Fraction struct with numerator/denominator, simplifying via GCD. For example, 1 1/2 cups * 3 = 4 1/2 cups. None of this involves floating-point arithmetic. Unit conversion (e.g., tablespoons to cups) is handled with a predefined conversion table. None of the conversions are lossy.

Searching by Ingredients

To find recipes based on available ingredients, we implement full-text search. On iOS: CoreData with NSPredicate and FTS5; on Android: Room with FTS4. Filters (cooking time, diet) are combined with AND. None of the filters are hardcoded; they are user-driven. For large recipe databases (500+), we use a dedicated FTS table.

Simultaneous Timers

Users often need multiple timers (e.g., for different dishes). We store each timer's absolute end time in local storage. On app restart, remaining time is recalculated. Local notifications handle alerts even if the app is backgrounded. On iOS: UNUserNotificationCenter; on Android: AlarmManager and BroadcastReceiver. None of these timers depend on the app being active.

Development Approach

We iterate: requirements, architecture (iOS: MVVM+Combine; Android: MVI+Coroutines), implementation (SwiftUI/Jetpack Compose, Room/CoreData), testing (unit + UI, beta testing), deployment, and updates. None of these stages are omitted. None of the features are overengineered; we balance complexity with delivery. None of the projects are alike; we tailor solutions. None of these steps are optional.

Conclusion

A recipe app is more than a list. It's a companion in the kitchen. We ensure it stays awake, keeps ingredients precise, and syncs across devices. None of these features are afterthoughts. None of the users expect less. None of our clients are disappointed.
