ResearchApp allows you to take part in a study that you've consented to participate in. In order to be able to join a study you will need to enter your token code that would have been provided to you by an organisation conducting the research. ResearchApp has been developed to help research teams accelerate new medicines discovery and to find ways to improve health outcomes for people all over the world. None of this can be achieved without the generous time and participation of research participants. If you have any questions about the study you are participating in, please contact the organisation conducting the study.

Verdict
The clearest difference is review sentiment: PROBr at 100% against ResearchApp's 0%. PROBr also leads on rating (5.0 vs 2.0) and ratings volume (5 vs 1). ResearchApp's advantage is update cadence (fortnightly vs every 6 weeks) and iOS requirement (10.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
