Verdict

The call

The clearest difference is price: Digital DoF at Free against Lens's $2.99. Digital DoF also leads on update cadence (monthly vs every 18 months) and ratings volume (274 vs 8). Lens's advantage is in-app purchases (none vs 10) and ads (none vs shown). On rating, review sentiment and device support there is nothing between them.
