Verdict
The clearest difference is ads: Fast Chart at none against SizeSnap's shown. Fast Chart also leads on iOS requirement (13.0 vs 15). SizeSnap's advantage is rating (4.9 vs 4.5) and monetization model (ad-supported vs free with in-app purchases). On price, ratings volume, update cadence and in-app purchases there is nothing between them.
