# POPGuide vs Gray Line

The clearest difference is rating: Gray Line at 4.9 against POPGuide's 4.3. POPGuide's advantage is ratings volume (3.6K vs 7) and chart position (#173 vs unranked). 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.

Gray Line holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: POPGuide has 3.6K ratings behind it against 7, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 26, 2026 and September 18, 2026 respectively.
