Scalable Notifications: Cross-Platform App Boilerplate
March 14, 2025
Are you ready to keep your users engaged—no matter what device they use? If you want your app to succeed, you need to reach people where they are: on their phones, tablets, and computers. But building a notification system that works seamlessly across iOS, Android, and the web is one of the hardest parts of modern app development.
In this guide, you'll learn:
- Why notifications are so complex across platforms
- The most common mistakes teams make
- How the MoneyMouth boilerplate saves you months of work
- Real-world examples and actionable tips
Let's dive in!
1. The Hidden Complexity of Cross-Platform Notifications
At first glance, sending a push notification seems easy. You write a message, hit send, and your users get it. Right?
Not quite. The reality is much more complicated. Here's what you're really up against:
Multiple Providers, Multiple Headaches
- Android & Web: Use Firebase Cloud Messaging (FCM)
- iOS: Uses Apple Push Notification Service (APNs)
- Browsers: Sometimes need custom solutions
Each provider has its own rules, APIs, and quirks. You can't just write one piece of code and expect it to work everywhere.
Timezone-Aware Scheduling
Imagine you want to remind users to check your app at 8 AM. But your users live all over the world. If you send a notification at 8 AM UTC, some people will get it in the middle of the night!
Solution: You need to schedule notifications based on each user's local time. This means tracking timezones, handling daylight saving changes, and more.
Platform Quirks and Payloads
- Each OS expects a different payload format.
- Delivery guarantees vary. Some platforms drop notifications if the device is offline.
- Background restrictions can prevent delivery if your app isn't running.
User Permissions: The First Hurdle
Getting users to opt in to notifications is a challenge. Many people say no, especially if the prompt appears too soon or without context.
Tips to Improve Opt-In Rates:
- Explain the value before prompting
- Offer granular controls (e.g., only important updates)
- Respect user choices and make it easy to change settings
Reliability: Delivering Every Time
Notifications must be delivered instantly, but also retried if they fail. Network issues, device settings, and server errors can all cause problems.
Analytics: What Works, What Doesn't?
You need to know which notifications drive engagement. Are users opening your app? Are they clicking links? Without analytics, you're flying blind.

Integration with Payments & Auth
Notifications often tie into purchases, renewals, or account activity. For example:
- Remind users about expiring subscriptions
- Alert them to successful payments
- Notify about suspicious login attempts

2. Why Most DIY Approaches Fall Short
Many teams think, "How hard can it be?" and start building their own notification system. Here's what usually happens:
Weeks (or Months) Lost
Wiring up FCM, APNs, and web push for each platform takes much longer than expected. Every platform has its own documentation, edge cases, and gotchas.

Bugs and Missed Messages
- Retrying failed notifications is tricky
- Handling background delivery is different on every OS
- User permission changes can break your logic
Scaling Issues
As your user base grows, you need to send thousands of notifications per minute. DIY solutions often can't keep up, leading to delays or dropped messages.
Maintenance Headaches
APIs change. Platforms update their requirements. What worked last year might break tomorrow. Keeping up is a full-time job.
Real-World Example: A SaaS startup spent three months building their own notification system. When iOS updated its background delivery rules, half their notifications stopped arriving. They had to scramble to rewrite their code—costing more time and money.
