This is also a category of app that I believe could be better served by local-first native apps. As there is no reason why a server has to be requirement to enjoy the full service. Your computer is fully capable of interacting with these webpages directly....
On Apple ecosystem, there are few alternatives one can migrate to. I also created an app that target this category (and more) called DoubleMemory: https://doublememory.com that has a few different takes as well:
- no registration needed (icloud sync)
- no extension required (just double command + c)
- launches from menu bar as a launcher, in a stunning Pinterest-style waterfall grid
It's all free to use with no limits, as i'm still working on paid features. I'll work on a pocket importer for these who are interested in migrating.
