Verdict
The clearest difference is review sentiment: IOU at 60% against Expense Split's 33%. Expense Split's advantage is rating (4.7 vs 4.4) and iOS requirement (16.6 vs 26.0). On price, ratings volume, update cadence and ads 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. Expense Split sells 4 one-off in-app purchases and IOU sells 5 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Expense Split holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 20 and 17 respectively. Written reviews complicate that: 33% of Expense Split's written reviews are positive against 60% of IOU's, so the app with the better star average is not the one people write more warmly about.
Expense Split ships an update every 2 weeks, IOU fortnightly. The most recent releases landed on July 30, 2026 and September 21, 2026 respectively.
