# HGS vs İDO Mobile

The clearest difference is rating: HGS at 4.6 against İDO Mobile's 2.7. HGS also leads on ratings volume (1.2K vs 15) and review sentiment (17% vs 4%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

HGS holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: HGS has 1.2K ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 17% of HGS's written reviews are positive against 4% of İDO Mobile's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
