Yes, Check is free to download and use! The way we make money is by charging a 1% transaction fee when you choose to process payments through Check but that's entirely optional.
Yes. If you choose to accept payments through Check (entirely optional), the payments will be processed through Stripe, our payment processor. Stripe takes 2.9% + $0.30 per transaction which is the industry standard among payment processors and Check takes an additional 1%.
Not at this time. Since we are dedicated to serving solo operators who are often running their business from the road, we decided to build an amazing mobile experience first before building a web app. Check currently only supports iOS and Android. However, we do have plans to build a web app in the future.
Developing software for hundreds of different devices and operating systems means there will probably be issues that we don't catch before we release a new version. Since we can't catch everything, we hope that you'll be willing to be an extra pair of eyes for us and send us a bug report so we can get it fixed ASAP!
