# Partial Sums Addition vs Algebra Fun

The clearest difference is review sentiment: Algebra Fun at 88% against Partial Sums Addition's 50%. Algebra Fun also leads on ratings volume (104 vs 2) and update cadence (every 3 months vs every 9 months). Partial Sums Addition's advantage is rating (5.0 vs 4.5) and price ($3.99 vs $7.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

Partial Sums Addition costs $3.99 and Algebra Fun $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Partial Sums Addition holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Algebra Fun has 104 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Partial Sums Addition's written reviews are positive against 88% of Algebra Fun's, so the app with the better star average is not the one people write more warmly about.

Partial Sums Addition ships an update every 9 months, Algebra Fun every 3 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
