Secure Shield's advantage is ratings volume (211 vs 2) and iOS requirement (15.0 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Secure Shield sells 4 in-app purchases, starting at $9.99 per 7 days and Bubble Level sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
