# GMX vs CHECK

The clearest difference is review sentiment: GMX at 77% against CHECK's 20%. GMX also leads on rating (4.7 vs 2.4) and update cadence (fortnightly vs every 3 months). CHECK's advantage is in-app purchases (none vs 19) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. GMX sells 12 in-app purchases, starting at $0.99 per month. CHECK asks for nothing beyond the download.

GMX holds the better App Store score, 4.7 against 2.4. That said, the two scores are not equally well evidenced: GMX has 17K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 77% of GMX's written reviews are positive against 20% of CHECK's.

GMX ships an update fortnightly, CHECK every 3 months. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
