# 1С vs ТСД

The clearest difference is in-app purchases: 1С at none against ТСД's 1. 1С also leads on review sentiment (30% vs 0%). ТСД's advantage is update cadence (monthly vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. ТСД sells 1 in-app purchase, starting at $17.99 per year. 1С asks for nothing beyond the download.

1С ships an update every 4 months, ТСД monthly. Both last shipped on November 3, 2026.
