Of the answers posted here I am curious if any of them are suitable for mobile (iOS/Android) or desktop (Mac/Windows) apps, or if they are all web-oriented?
PostHog has iOS/Android/Flutter/React Native libraries for analytics - full details https://posthog.com/docs/integrate#client-libraries. We don't have session recording / feature flags everywhere yet though (I work there)
Do the PostHog Android and iOS libraries automatically collect & report metrics like OS version & app version so I can easily track how many users are on each version? We're still using Flurry right now but looking for a replacement.
Yep! See [0] for an overview of the properties we automatically collect
Every time this question / topic comes up, I read through the replies and can never find one for Mobile apps. I guess it might be time to start my own.
