Frequently Asked Questions

Q: What phone do I have to have for Rezistr to work?

A: iPhone only, 6 and up

Q: Is Rezistr free?

A: Yes, a limited version of Rezistr is free to download, but an in-app purchase provides full access to the app the way it was intended to be used. The free version does not provide full resistor values.

If you are satisfied with Rezistr using the free version, please feel free to support the project and purchase the in-app upgrade!

Q: What do I need in order to get Rezistr to work?

A: A white piece of paper is required in order to reduce the possibility of background interference. If a white piece of paper isn't readily available, a solid color background is the next best thing.

Also, resistors are pretty important.

Q: What if Rezistr doesn't work for me?

A: If Rezistr doesn't work for you, let us know! Rezistr was tested on a variety of iPhones in a multitude of lighting scenarios, and the app is made to instruct the user to use it in a way that produces the best results possible, but it is still growing and improving with each update to ensure results on a multitude of devices.

If you can't get Rezistr to work, send us an email and we can work with you to figure out the issue.
