Verdict

The call

The clearest difference is price: Picture Insect at Free against Gradin's $3.99. Picture Insect also leads on chart position (#87 vs unranked) and iOS requirement (15.0 vs 18.1). Gradin's advantage is in-app purchases (none vs 10) and update cadence (every 8 days vs every 5 weeks). On ads and device support there is nothing between them.
