Verdict
The clearest difference is rating: Hi at 5.0 against Flash's 4.1. Hi also leads on review sentiment (100% vs 67%) and update cadence (every 6 days vs monthly). Flash's advantage is ratings volume (48 vs 3) and iOS requirement (11.0 vs 15.0). On price, ads, 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. Neither carries in-app purchases, so what you see is what you pay.
Hi holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Flash has 48 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 67% of Flash's written reviews are positive against 100% of Hi's.
Flash ships an update monthly, Hi every 6 days. The most recent releases landed on October 24, 2026 and October 14, 2026 respectively.
