# GMX vs Shliff

The clearest difference is ads: Shliff at none against GMX's shown. Shliff also leads on iOS requirement (15.0 vs 18.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. GMX sells 7 in-app purchases, starting at $0.99 per month and Shliff sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
