Verdict
The clearest difference is review sentiment: Sumaddle at 95% against Akari's 40%. Sumaddle also leads on ads (none vs shown) and rating (4.9 vs 4.6). On price, update cadence, in-app purchases and monetization model 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. Sumaddle sells 15 one-off in-app purchases and Akari sells 29 in-app purchases, starting at $0.79 per 7 days. Whichever you choose, the download price is not the number that matters.
Sumaddle holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Sumaddle has 767 ratings behind it against 30, so its average is the more settled of the two. Written reviews point the same way: 95% of Sumaddle's written reviews are positive against 40% of Akari's.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 21, 2026 and September 5, 2026 respectively.
