Verdict
The clearest difference is ads: Lyn at none against Flashka's shown. Lyn also leads on review sentiment (100% vs 80%) and rating (5.0 vs 4.8). Flashka's advantage is ratings volume (398 vs 2). 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. Lyn sells 3 in-app purchases, starting at $4.99 per month and Flashka sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Lyn holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Flashka has 398 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of Lyn's written reviews are positive against 80% of Flashka's.
Lyn ships an update every 3 weeks, Flashka fortnightly. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
