Verdict
The clearest difference is review sentiment: Lens at 69% against Alpha Linker's 16%. Lens also leads on in-app purchases (none vs 1) and rating (4.6 vs 4.3). Alpha Linker's advantage is price (Free vs $2.99) and update cadence (every 2 months vs every 18 months). On ads and device support there is nothing between them.
