Gemm review for ABConvert: A/B Testing

Amazing app, bad operation. The functionality of the app itself is great- you can run tests that improve your conversion rate by 0.1%, which is a lot. However, the app lacks in support and self-support- not because of the support staff, but because of the working hours and the way errors are not communicated. I've attempted creating the same price test over 10 times by now- each time, taking ~30 minutes. Once the test fails, all it does is not show up in the "Your tests" section- no visible feedback on why it failed. The support works 9am to 6pm- Beijing time- meaning during regular business Hours in the Americas, you have no support.
