Verdict

The call

The clearest difference is rating: GR Lab at 4.1 against Image Sync's 1.8. GR Lab also leads on review sentiment (50% vs 13%) and update cadence (every 9 days vs every 3 months). Image Sync's advantage is in-app purchases (none vs 6) and ratings volume (200 vs 24). On price, ads and device support there is nothing between them.
