Install our SDK and integrate into your app following our Quick-Start Guide. This only takes about 15 minutes.
Yes, really β a growth plan defined in JSON. You can add features without any additional code. If you want deeper integrations, custom hooks are available.
Use our guides to get started with ready-to-deploy and proven growth tactics. We're building a growing library of examples you can use for inspiration.
Once your initial growth plan is deployed, you can update anytime without waiting for app reviews or App Store updates. Add growth features without new code, anytime, over the air. Update and tune your user targeting logic, including in past app releases.
- Notifications: Our smart notifications target delivery to the perfect moment, considering realtime device condition. Start with our templates to increase activation, reduce churn, and custom notifications.
- Improve your App Rating: use our template to ask users to rate your app at the perfect moment, increasing your rating and rating volume.
- Optimize Revenue: ask users to upgrade at the perfect moment, with over 100 built-in targeting properties.
- In-app Messaging: add fully native messaging UI without writing any code. Options include banners, modals, alerts, browser, and more. All themed to match your brand.
- Smart Feature Flags: define feature flags that can be updated in real-time based on over 100 real-time device conditions (low battery, has network, permissions, etc).
- Over The Air Updates: Update your growth plan anytime without app updates. Quickly recover from unexpected bugs, outages, deprecations, and other critical events.
With Critical Moments, you can target users with the right actions at the perfect moment:
Our simple string-based conditional statements can check over 100 built-in properties, custom properties, in-app events, and user engagement history.
Some examples:
eventCount('app_launch') > 5 && latestEventTime('asked_to_subscribe') < now() - duration('72h')device_model_class == 'iPad' && versionLessThan(app_version, '2.4.1')camera_permission != 'authorized' && photo_library_permission != 'authorized'has_watch || location_city == 'Toronto' || has_car_audio || on_call || has_bt_headset || network_connection_type == 'cellular'weather_condition IN ['Rain', 'Thunderstorms'] || weather_cloud_cover > 0.80
Define exactly when actions should occur, based on in-app event triggers.
The most commonly needed actions are tracked automatically. Add your own custom events or properties with a single line of code.
Our SDK automatically starts building an on-device database of user engagement history. Use this database when targeting user-messaging, reviews, notifications, paywalls and more! For example: eventCount('session_start') > 3 && latestEventTime('asked_to_subscribe') < now() - duration('24h') && !propertyEver('has_paid_subscription', true)
Critical Moments is designed from the ground up for user privacy. All logic is run locally on their own device. We donβt collect any information about your users. A default installation makes zero calls to our servers from the userβs device. Learn more about our privacy architecture in our blog post.
Note: Some optional services like GeoIP location and weather require external services. These are clearly outlined in our docs. They are completely optional, do not collect user identifiers, and do not store logs long-term.
Our Quick-Start guide will get you up and running with the Critical Moments SDK in just a few minutes.
