# Speed Reading IQ vs Celer

The clearest difference is rating: Speed Reading IQ at 4.6 against Celer's 4.0. Speed Reading IQ also leads on ratings volume (235 vs 21) and iOS requirement (13.0 vs 18.0). Celer's advantage is ads (none vs shown). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Speed Reading IQ sells 1 one-off in-app purchase and Celer sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Speed Reading IQ holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Speed Reading IQ has 235 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 55% of Speed Reading IQ's written reviews are positive against 57% of Celer's, so the app with the better star average is not the one people write more warmly about.

Speed Reading IQ ships an update every 2 weeks, Celer every 9 days. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
