FTFY

You can download an apk from the releases page.

there’s no way to activate pro right now, and afaik that option is not coming.

Since beta 25 it is now possible (and the developer had mentioned before that it was coming).

Edit: I stand corrected (should have read your comment more attentively), what’s available is, as you say, the option to remove ads with a one-time payment, as well as the sync ultra subscription. I’m not sure how the ad removal option is different from the pro mode in sync for reddit, though.

You know what, I had paid for the lifetime pro mode in sync for reddit, and usually prefer one-time payments to recurring subscriptions, but I chose to go with the recurring ultra subscription this time, to contribute to your regular financial stability. Your dedication is commendable. Thanks for all the work you’ve done over the years!

Workflowy and Teuxdeux are two web apps where I spend an embarrassingly large amount of my time online. I wish there were FOSS alternatives because I would happily contribute features and fixes to the issues I bump into in my daily usage.
