# iSum vs Budget app

The clearest difference is rating: Budget app at 4.7 against iSum's 4.1. Budget app also leads on ratings volume (16K vs 24) and update cadence (every 4 days vs fortnightly). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. iSum sells 1 in-app purchase, starting at $2.99 per year and Budget app sells 8 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Budget app holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Budget app has 16K ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 83% of iSum's written reviews are positive against 79% of Budget app's, so the app with the better star average is not the one people write more warmly about.

iSum ships an update fortnightly, Budget app every 4 days. The most recent releases landed on October 26, 2026 and October 28, 2026 respectively.
