Amount of local phone storage nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 uses starts to become biggest problem for me. 
Free hosting on relays is the problem, it's faster and more reliable to store on the device than fetch. I guess there should be an alternative so it's not using 6GB locally though, which is excessive.
I think IPFS is a possible good match for Nostr because there's currently tons of free hosting thanks to the excessive money flying around the web3 world (see nft.storage for free and long term guaranteed IPFS / Filecoin hosting)
I guess it’s db not cache? As clear cache didn’t change anything. Storing some of the stuff on iCloud and re-download when needed would help in my case, my iPhone 7 has only 32 GB of internal storage. /cc nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s
We don’t have a db prune option yet, sorry. You will have to delete the app and reinstall. We will have this soon.
