Verdict
The clearest difference is rating: GR Lab at 4.0 against Image Sync's 1.8. GR Lab also leads on review sentiment (50% vs 13%) and update cadence (every 2 weeks vs every 3 months). Image Sync's advantage is in-app purchases (none vs 6) and ratings volume (197 vs 21). On price, ads and device support there is nothing between them.
