Verdict
The clearest difference is ads: IOU at none against Ledger Book's shown. IOU also leads on rating (5.0 vs 4.7). Ledger Book's advantage is ratings volume (15 vs 4) and iOS requirement (15.0 vs 17.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
