App-Entwicklung: Push Notifications & Realtime
An app that goes silent gets forgotten. Push notifications and realtime features keep users informed, increase return rates, and turn your app into a live channel rather than a static tool. We implement reliable push infrastructure and realtime connections for chat, live updates, and collaborative features – scalable and with well-designed opt-in logic.
Challenges you'll recognise
- The majority of your users have disabled push notifications because they find them intrusive.
- Your chat feature lags several seconds behind – users complain it does not feel real-time.
- Push delivery rates are low and you cannot tell whether it is a technical or an opt-in problem.
Push Infrastructure
Reliable push notifications require more than a single API call. We set up the complete infrastructure: server-side delivery via APNs and FCM, token management, segmented audiences, and retry logic for failed deliveries. Your notifications arrive – even when the app is in the background or not currently active.
Opt-in Strategy
Aggressive push messaging loses users. We implement a thoughtful opt-in logic: contextual explanation before the system prompt, granular settings per notification type, and easy management inside the app profile. Users who consciously opted in open notifications far more often.
Realtime Connections
Chat, collaborative features, live scores, or real-time status updates require persistent connections. We implement WebSocket or SSE-based realtime infrastructure that scales with your app, handles graceful reconnects, and works efficiently with mobile network conditions.
Offline Handling
Realtime features must also behave sensibly offline. We implement local queues that buffer changes and synchronise on reconnect – so users on weak connections do not walk into a broken app experience.
Good to know
APNs and FCM Infrastructure
Professional push notifications run through Apple Push Notification Service and Firebase Cloud Messaging. We build the server-side infrastructure that manages tokens, tracks deliveries, and handles errors automatically.
Realtime Without Polling
Polling – the app repeatedly asking for updates – drains battery and burdens servers. WebSocket-based realtime connections deliver updates instantly and are more resource-efficient than a naive polling interval.
Privacy-Compliant
Push notifications and realtime data must be processed in compliance with GDPR. We implement privacy-compliant opt-in flows and ensure no personal data is unnecessarily persisted.
