# DRS vs C

The clearest difference is review sentiment: C at 88% against DRS's 28%. C also leads on rating (4.8 vs 4.2) and update cadence (every 2 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. DRS sells 1 one-off in-app purchase and C sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

C holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 1.9K and 6.8K respectively. Written reviews point the same way: 28% of DRS's written reviews are positive against 88% of C's.

DRS ships an update every 2 months, C every 2 weeks. Both last shipped on October 20, 2026.
