Verdict
The clearest difference is ads: Going Blue at none against Mountain's shown. Going Blue also leads on update cadence (every 8 days vs every 2 months) and monetization model (free vs free with in-app purchases). Mountain's advantage is ratings volume (845 vs 4) and chart position (#60 vs unranked). On price, rating, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Mountain sells 2 in-app purchases, starting at $3.99 per month and Going Blue sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for Mountain against 5.0 for Going Blue. That said, the two scores are not equally well evidenced: Mountain has 845 ratings behind it against 4, so its average is the more settled of the two.
Mountain ships an update every 2 months, Going Blue every 8 days. The most recent releases landed on November 14, 2026 and November 13, 2026 respectively.
