Bandwidth usage in Damus Notedeck is very good. I was using it on an airplane and it worked great.

On first open it has the notes from the previous session, so it can optimize filters right away for every column, so you only have to pull down a few thousand bytes instead of megabytes. Damus iOS currently does not do this but we will be switching to the local relay model so eventually it will.

The desktop version has a powerful command line interface, so you can do very specific and optimized things like launching the app with only a single relay in your pool, launching with only lightweight queries, and launching with image loading disabled, so bandwidth use can be near optimal for power users and in extreme conditions. nostr:note1d4s0whljtd6jv7pelmkypheyjql5awyfpkjrjdzjxa2rywvxu2fsxgau2l
