FreeRBX offers two survey providers, CPX Research and TheoremReach, and both credit the same points balance at the same conversion. Neither is universally better: they carry different inventory, so the right move is trying both and doubling down on whichever matches your profile.
How they differ
- Format: CPX renders an embedded wall on the Earn page; TheoremReach opens in the same tab from its own button. Return to Earn when finished.
- Inventory: each provider contracts different researchers, so a dry spell on one often coincides with availability on the other.
- Pending windows: surveys on both usually confirm within minutes to hours; TheoremReach game-install offers can pend for days until goals register.
A practical order
Start with the CPX wall since it loads inline with no tab-switching. If it shows no surveys for your profile, open TheoremReach next rather than retrying the same wall. Complete profilers on both: matching data does not transfer between providers.
One account, one balance
Rewards from either wall land in the same FreeRBX balance and the same withdrawal queue at 2,000 points. Provider choice affects which surveys you see, never the point value of a dollar: 300 points per $1 of credited revenue applies to both.
