The clearest difference is ratings volume: Astra AI at 5.4K against Etchd.ai's 1. Astra AI also leads on chart position (#115 vs unranked). Etchd.ai's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Astra AI sells 10 in-app purchases, starting at $8.00 per 7 days and Etchd.ai sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
