BJJ Notes alternative?

I've been using BJJ Notes on Android and like it. My use of it is rudimentary , so my requirements aren't high.

But there are a few features that I'd like that require upgrading to pro (long term stats like how many classes I've been to total).

I don't mind paying for an app, but I hate apps that make you subscribe monthly versus paying once.

Is there an app that's similar that isn't a monthly subscription? Free or paid.

Thanks
