Standalone vs. Cross-platform: choosing the right project

When setting up a new project in devtodev, one of the first and most consequential decisions you'll make is choosing between a standalone and a cross-platform project type.

This choice is permanent – you cannot switch a previously created devtodev project to the cross-platform type – so it's worth getting right from the start.

It is also impossible to send data from one application to both types of projects simultaneously.

What's the Difference?

A standalone project tracks a single platform (e.g., iOS, Android, or PC). Each platform gets its own devtodev project with its own user base, metrics, and reports.

Best for: subscription apps, apps that use A/B testing or push campaigns heavily, or any app where platform-specific reporting is a priority.

A cross-platform project is designed for apps that share a user base across multiple operating systems. It combines user data from multiple platforms under a single project, giving you a unified view of your audience.

Best for: productivity or utility apps available on multiple OSes, or any product where understanding the full cross-device user lifecycle is more valuable.

When to choose Standalone

A standalone project is the right fit when:

• Your app targets a single platform. A standalone project is simpler and fully featured.

• Most of your users are interacting with only one platform (device) and you want to analyze them independently without cross-contamination of metrics.

• You use Push Notifications, A/B tests, or Remote Configuration. If these are part of your growth toolkit, select standalone.

• You track subscriptions. Subscription tracking and the Subscriptions report are available only for standalone projects.

• You rely on store integrations. Standalone projects support market data integrations with Google Play, the Apple App Store, and others. Cross-platform projects do not support store integrations for market data.

• You need cohort exports. Cohort export is available only in standalone projects.

When to choose Cross-platform

A cross-platform project makes sense when:

• Most of your users run the app on different devices with the same account frequently. You can see the history of users and metrics across all platforms in one place

• You want a unified user identity across platforms. Cross-platform projects give users the same devtodev ID on all platforms (in devtodev). This lets you track the full journey of a single user regardless of what device they're on.

• You can manage the technical prerequisite. Cross-platform projects require you to use your own custom identifiers (User ID).

• You need cross-platform behavioral insights. The User Card shows all events a user performed on different platforms, and most reports include a platform filter so you can drill into individual platforms when needed.
