When the user in not actively using mobile phone then push notification came into action because it allows sending timely and relevant messages to users. It’s a powerful way to re-engage users, enhance utility, provide value, and drive conversions for iOS apps.
We are going to find out the types of push notifications, use cases, best practices and strategies to maximize their impact in iOS app development.

Overview of Push Notifications

These are the type of notifications like messages delivered from an app server to a user’s device that get displayed on the screen. Notification reminds user to open the app even when the app is closed or phone is locked so that the user may check his or her device for any new activity or time sensitive information.

On Apple devices, notifications appear as pop-ups or banners at the top of the screen. Users can view, dismiss or action them. iOS allows configuring notification settings per app. Apps must explicitly request user permission to send notifications.

Types of push notifications:

• Alerts - Simple text alerts about events, new content etc.
• Sounds - Play audio snippets like chimes and dings.
• Badges - Update red badges on app icons indicating number of new items.
• Interactive - Buttons to trigger actions like replies. Requires iOS 10+.
• Silent - Hidden notifications without alerts.
• Well-crafted notifications provide value and convenience to users while achieving business goals like boosting engagement.

Powerful Use Cases for Notifications

Here are some common and effective use cases for push notifications:

• New content or features: Alert users to fresh app content like articles, videos, episodes, playlists, deals etc.
• Activity from contacts: Notify about actions from friends/connections like likes, comments, messages.
• Appointment/event reminders: Remind about upcoming bookings, meetings, travel times, events etc.
• Shipping status alerts: Update users on order/delivery status and ETAs.
• Public transit updates: Notify delays, disruptions affecting commutes.
• Price drop alerts: Notify when watched items go on sale.
• Chat/messaging alerts: Inform about new messages and unread counts.
• Promotional alerts: Offer coupons, deals, exclusive sales based on user context.
• Sports updates and scores: Provide live game and fantasy sports updates.
• News and content recommendations: Suggest personalised content based on preferences.
• Application crashes: Notify unexpected crashes and prompt restarts.
• Security alerts: Warn about suspicious account activity.

Getting creative with notifications can really enhance user experience and satisfaction for iOS apps across all verticals.

Crafting Effective Notifications

Follow these tips to craft notifications that deliver value rather than annoyance to users:

• Provide Context - Include readable text that summarizes what the notification refers to avoid confusion. Don’t make users dig through the app to find relevance.
• Personalize - Use names, customize notifications based on user data and context. Targeted messages are more meaningful.
• Actionable - Make notifications interactive with action buttons. Allow managing the referenced content right from the notification.
• Concise - Be brief. Get to the point quickly in a few words. Long text risks the notification being ignored.
• Timely - Send notifications when most useful to the user, not just when it suits business needs. Relevance boosts interest.
• Infrequent - Avoid spamming users excessively. Send only high-value alerts that warrant interrupting users.
• Allow Opt-Out - Provide user controls to disable notifications or limit their frequency. Don’t force notifications.
• Segment Users - Customize notification categories and frequency based on user personas and preferences.
• Test Effectiveness - Analyze performance data for click-throughs, conversions, opt-outs to refine approach.
• Respect OS Settings - Follow OS conventions and respect user notification settings for acceptable delivery times.
• Use Responsibly - Never use notifications for harmful, unethical or creepy purposes that violate user trust.

By making notifications helpful rather than intrusive, you can greatly boost their impact.

Best Practices for Technical Implementation

Here are some key best practices to follow when implementing push notifications technically:

• Request Permission - Prompt users for notification permission only at contextual moments, not unexpectedly. Set context before requesting access.
• Follow Apple Guidelines - Comply with all Human Interface Guidelines for standard UX patterns.
• Handle User Settings - Check and respect the user’s notification settings when sending notifications. Never spam.
• Leverage Notification Framework - Use iOS notification framework UserNotifications to manage scheduling, local notifications etc.
• Support Interactive Notifications - Implement actionable buttons for quick in-context actions where relevant.
• Handle Payloads Efficiently - Minimize notification payload size for efficiency. Use background fetch for larger downloads.
• Test Targeting - Test segmentation to ensure notifications reach the right users accurately based on targeting rules.
• Set Up Tracking - Track key metrics like sends, deliveries, views, actions. Analyze data to optimize.
• Follow Up Locally - For critical alerts, ensure adequate local app follow-ups even if user dismisses notification.
• Provide Settings - Allow users to customize notification categories, frequency and other preferences.
• Ensure Security - Use end-to-end encrypted channels to protect notification contents and user data.

Optimizing technical implementation and continuously monitoring and improving performance are key to notification success.

Avoiding Notification Pitfalls

Be sure to avoid some common notification anti-patterns that hurt the user experience:

• Excessive Frequency - Limit notification frequency to avoid constantly pestering users. Set sane defaults.
• Irrelevant Messages - Don’t spam everyone with notifications unrelated to them. Target individual needs.
• Alarming Wording - Don’t stress users with ominous wording like “Urgent!” when unnecessary.
• Alert Floods - Space out notifications. Don’t flood with a burst of messages at once.
• Interruptions at Odd Times - Avoid sending non-critical alerts late night or early morning.
• Impersonal Messages - Don’t send blanket generic notifications. Customize content.
• All Caps Wording - Capitalized letters in alerts reads as shouting. Use normal title case formatting.
• Wrong Notifications - Ensure notifications match their linked app content. Don’t promise one thing but open something else.
• Critical Notifications Overused - Reserve critical notification types like red badges for true urgent scenarios only.
• Poorly Timed Notifications - Don’t send time-sensitive alerts long after the moment has passed. Promptness is key.

Avoiding these notification antipatterns helps build user trust and engagement over time.

Notification Strategies for Business Impact

Here are some proven notification strategies to boost key business metrics for iOS apps:

• Boost Activations - Trigger multi-step onboarding tutorials via notifications to activate new users.
