Verdict
The clearest difference is price: Sift at Free against Pascal's $2.99. Sift also leads on in-app purchases (none vs 3) and iOS requirement (15.1 vs 17.6). Pascal's advantage is ads (none vs shown) and update cadence (every 2 weeks vs monthly). On device support there is nothing between them.
