# Quick sum vs Sum

The clearest difference is rating: Sum at 5.0 against Quick sum's 4.2. Sum also leads on update cadence (every 3 days vs every 12 months). Quick sum's advantage is ads (none vs shown) and ratings volume (9 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Quick sum sells 1 one-off in-app purchase and Sum sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Sum holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Quick sum has 9 ratings behind it against 1, so its average is the more settled of the two.

Quick sum ships an update every 12 months, Sum every 3 days. The most recent releases landed on October 17, 2026 and October 13, 2026 respectively.
