# TopInfrared vs SECA

The clearest difference is rating: TopInfrared at 3.5 against SECA's 2.0. TopInfrared also leads on review sentiment (40% vs 25%) and ratings volume (48 vs 4). SECA's advantage is in-app purchases (none vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. TopInfrared sells 1 one-off in-app purchase. SECA asks for nothing beyond the download.
