I’ve never used Relay so I couldn’t say for certain but I believe it wouldn’t work in that case. IIRC the Relay app was updated to the subscription model of access like reddit was trying to force on everyone. If that’s the case being a mod won’t change the hardcoded behavior of the updated app.
This workaround works with Boost without any kind of updating or patching, so if there’s a third party app that did what Boost did (stopped updating but left the app otherwise intact) there’s probably a fair chance the same process will work. Any of the apps that continued to update or deleted API keys would have a much harder time I’d imagine.
I think it’s meant to be similar to the Crafty+ with a couple upgrades at a more competitive price point. The removable battery would be a welcome change, but a smaller chamber might mean even more interruptions to sessions.
I’d like to see a direct comparison between those two addressing vapor production and quality. For the price it’s pretty tempting just for the battery options though.
