Verdict
The clearest difference is in-app purchases: Yesterday at none against Mountain's 2. Yesterday also leads on ads (none vs shown) and update cadence (every 8 days vs every 2 months). Mountain's advantage is rating (4.9 vs 4.5) and ratings volume (832 vs 2). On price there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mountain sells 2 in-app purchases, starting at $3.99 per month. Yesterday asks for nothing beyond the download.
Mountain holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Mountain has 832 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 74% of Mountain's written reviews are positive against 100% of Yesterday's, so the app with the better star average is not the one people write more warmly about.
Mountain ships an update every 2 months, Yesterday every 8 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
