About

Expoll

Features
Read full description

Expoll is a voting website similar to other woll-known voting/polling websites. We tried to combine both in a neat small and easy-to-use website. Unlike the well-known platforms, who delete polls after a quite short time, or where you have to be logged in with an active session to even get the chance to vote for something withing a few minutes, we are trying to keep every vote possible (though probably have to restrict the creation of polls to about 5-10 per user at a time in the future).

Verdict

The call

The clearest difference is in-app purchases: I at none against Expoll's 4. I also leads on update cadence (every 9 days vs every 2 months) and iOS requirement (8.0 vs 16.4). On price, ads and device support there is nothing between them.
