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.
Giveffect holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: Katasymbol has 276 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of Giveffect's written reviews are positive against 26% of Katasymbol's, so the app with the better star average is not the one people write more warmly about.
Giveffect ships an update fortnightly, Katasymbol monthly. The most recent releases landed on October 2, 2026 and October 11, 2026 respectively.
