...And the all of the features that are currently available will always be free.
If you sign up for the free account (the only one we offer right now), you can be confident that you'll be able to keep on using it for free. We won't suddenly start to charge for the use of Really Simple Lists.
We do have plans to introduce a premium version at a later date, with lots of extra features, but we'll continue to offer the free version, and this won't affect your free use of the service in any way. We'll continue to improve the free version too, so if you're using the this edition, we won't leave you behind.
