Verdict
The clearest difference is ads: Fast Math at none against Math Prep for GRE's shown. Fast Math also leads on rating (5.0 vs 4.7) and update cadence (every 4 months vs every 13 months). Math Prep for GRE's advantage is review sentiment (100% vs 67%). On price, ratings volume, in-app purchases 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. Math Prep for GRE sells 1 one-off in-app purchase and Fast Math sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Fast Math holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 3 and 2 respectively. Written reviews complicate that: 100% of Math Prep for GRE's written reviews are positive against 67% of Fast Math's, so the app with the better star average is not the one people write more warmly about.
Math Prep for GRE ships an update every 13 months, Fast Math every 4 months. The most recent releases landed on November 1, 2026 and November 12, 2026 respectively.
