Write an app and earn from ads

📱 How to Write an App and Earn from Ads – Step-by-Step

---

✅ Step 1: Choose a Profitable App Idea

Pick something:

• Simple but useful (tools, calculators, habit trackers)

• Fun or addictive (games, puzzles, trivia)

• Niche-focused (local services, education, language learning)

App Type	Monetization Potential
Calculator/Utility	High ad impressions
Casual Game	High usage + rewarded ads
Learning App	High session time
Wallpaper App	High download volume
Journal or Tracker	Room for upsell + ads

---

✅ Step 2: Build the App (No-Code or Code)

Option 1: Use No-Code Tools (Beginner-friendly)

• Thunkable, Adalo, Kodular, Glide (for mobile apps)

• Many allow you to add AdMob ads easily

Option 2: Code It Yourself

Use:

• Flutter (Dart) – cross-platform (iOS & Android)

• React Native (JavaScript)

• Android Studio (Java/Kotlin)

• Xcode (Swift for iOS)

🛠️ If you're not a developer, I can help you write the core app logic or prototype to get started.

✅ Step 3: Integrate Ad Network (Like Google AdMob)

Popular mobile ad networks:

• AdMob (by Google) – best for Android/iOS

• Unity Ads – best for games

• Facebook Audience Network

• AppLovin, IronSource, Chartboost

You can use:

• Banner ads – appear at top/bottom

• Interstitial ads – full-screen, between screens

• Rewarded ads – users watch ads for in-app rewards

Example (Flutter + AdMob):

dart
MobileAdTargetingInfo targetingInfo = MobileAdTargetingInfo(
  keywords: <String>['productivity', 'games', 'learning'],
  childDirected: false,
);

BannerAd myBanner = BannerAd(
  adUnitId: BannerAd.testAdUnitId,
  size: AdSize.banner,
  targetingInfo: targetingInfo,
  listener: (MobileAdEvent event) {
    print("BannerAd event: $event");
  },
);

✅ Step 4: Publish on App Stores

Platform	Publishing Fee	Notes
Google Play Store	$25 one-time	Android, easier approval
Apple App Store	$99/year	Stricter guidelines

📌 Add good screenshots, an engaging description, and keywords for ASO (App Store Optimization)

💰 How Much Can You Earn from Ads?

Installs	Daily Active Users (DAU)	Est. Daily Earnings (AdMob)
5,000	500	$2 – $10/day
50,000	5,000	$20 – $100/day
500,000+	50,000+	$100 – $500+/day

Depends on ad type, user location (US/UK > Asia/Africa), and user engagement

---

🎯 Tips to Maximize Revenue

• Add rewarded video ads (they earn more than banners)

• Improve user retention (add daily rewards or streaks)

• Use ASO to get organic installs (keywords, reviews)

• Localize the app to more languages (bigger reach)
