According to my current economic situation I could find the best Nostr client on Android is called Satellite 🛰 satellite.earth, super optimal in data consumption and friendly with the battery, it lacks many things, but it is the one I can use, incredibly it lacks the option of likes and to be able to send sats, expecting better features in new updates.

The dude is coding his ass off 12+ hours a day 6 days a week-- flying solo. The site used to be based on torrent technology that was elegant and had full functionally. Then along came Nostr. He unplugged almost everything that made satellite.earth what it was, just to pivot to this protocol. Don't bail out on this too soon, it will be back to absolute brilliance as fast as he can make it happen. He was at Nostrica and won the whole enchilada at the hackathon. Keep spreading the word. This will be a super-client soon. He's flippin' brilliant.
