SessionFox can be used to record user mobile sessions of any app that includes the SessionFox SDK. From the SessionFox dashboard, user segments can be created and only sessions that match these user segments get recorded. The dashboard can be used to view all the recordings.
We are selling SessionFox because we found our passion to be elsewhere, in building web apps for e-commerce.
To someone buying this project, session recording is a lucrative business to serve lots of small and medium sized indie app developers on the Play Store. There is an opportunity to rack up 100s of users paying ~$50-100/mo and making a side project up to $5k-$10k MRR.
After a successful signup on app.sessionfox.com, an API key would be issued. This API key would have to be used by the android SDK, the documentation of which is here for the native android SDK and here for the react native SDK.
Post installation of this SDK, you would be able to create user segments from the app.sessionfox.com dashboard. A user segment can be created based on generic events such as screen visits, or custom events that would be defined using the SDK.
