Not sure what you mean by compatible. Probably you mean comparable (undoubtedly a mistype). If that is what you meant, I disagree. Though they go about it differently, both are personal knowledge management apps. Roam has set the high end of the cost of such apps at $150 a year. Other online apps cost in the same ballpark.

Akiflow is $15 per month
Amplenote is $10 per month
Evernote is $8 per month
Milanote is $10 per month
Reflect is $160 per year

My only point here is that where Tinderbox once seemed expensive, it is now right in the middle of the pack price-wise. And, it keeps working just fine if you stop paying your annual renewal.

The two apps are not directly compatible, and Roam has always been an
outlier in price compared to its direct competition.
