@river I would be happy to pay for the pro version, especially the mobile version,, but only as long as it's a one-time purchase, not a subscription. There are too many subscription services now, people are starting to get subscription fatigue. Having another regular money-sink is hard to justify for something so niche and specific as a dictionary. Would be happy to pay a bit more upfront to just have and own a version, rather than rent a license. Having said that, if there is a useful service that actually makes sense to require a subscription to access, something that would require you to maintain servers or provide regularly updated content, then I think having that as another subscription-based add-on would be acceptable.
