Verdict
The clearest difference is price: ClearView Flex at Free against f8 Lens Toolkit's $9.99. ClearView Flex also leads on review sentiment (100% vs 80%). f8 Lens Toolkit's advantage is rating (4.9 vs 4.5) and update cadence (every 2 months vs every 6 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
