Verdict
The clearest difference is ads: InDebt at none against Sono's shown. Sono's advantage is review sentiment (89% vs 59%) and ratings volume (23 vs 2). On price, rating, update cadence and in-app purchases 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. InDebt sells 1 one-off in-app purchase and Sono sells 11 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Sono holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Sono has 23 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 59% of InDebt's written reviews are positive against 89% of Sono's.
InDebt ships an update monthly, Sono every 3 weeks. The most recent releases landed on October 19, 2026 and October 24, 2026 respectively.
