What's new
Jul 1, 2026
I’m switching my payment model for NEW users to an affordable annual subscription plan. Before new users have to pay, they’ll have plenty of time to test all features without any restrictions. For EXISTING CUSTOMERS who have purchased the app at some point, nothing will change, and signing up for a subscription is optional—it’s a way to support the app’s continued development. I’ve also fixed a few bugs; all the improvements are listed on my website.
