# C vs ARGo Navigation

The clearest difference is ads: C at none against ARGo Navigation's shown. C also leads on chart position (#97 vs unranked). ARGo Navigation's advantage is update cadence (every 2 days vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. C sells 10 in-app purchases, starting at $1.99 per month and ARGo Navigation sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

C ships an update every 6 weeks, ARGo Navigation every 2 days. The most recent releases landed on September 23, 2026 and September 8, 2026 respectively.
