Verdict

The call

The clearest difference is rating: Check Splitter at 5.0 against IOU's 4.4. Check Splitter also leads on review sentiment (100% vs 60%) and in-app purchases (none vs 5). IOU's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (17 vs 3). On price, ads and device support there is nothing between them.
