Verdict
The clearest difference is rating: Harmony Helper at 3.9 against Letscappella's 3.0. Harmony Helper also leads on ratings volume (186 vs 2). Letscappella's advantage is in-app purchases (none vs 4) and iOS requirement (8.0 vs 13.0). On price, review sentiment, update cadence and ads 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. Harmony Helper sells 4 in-app purchases, starting at $4.99 per month. Letscappella asks for nothing beyond the download.
Harmony Helper holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Harmony Helper has 186 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Letscappella's written reviews are positive against 49% of Harmony Helper's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on June 6, 2026 and September 25, 2026 respectively.
