Verdict
The clearest difference is in-app purchases: Euki at none against Aavia's 20. Euki also leads on iOS requirement (13.4 vs 15.6). Aavia's advantage is rating (4.5 vs 4.1) and ratings volume (2.7K vs 116). On price, review sentiment, ads and device support 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. Aavia sells 17 in-app purchases, starting at $4.99 per month. Euki asks for nothing beyond the download.
Aavia holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Aavia has 2.7K ratings behind it against 116, so its average is the more settled of the two. Written reviews point the same way: 76% of Aavia's written reviews are positive against 70% of Euki's.
Aavia ships an update every 8 days, Euki every 3 weeks. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
