Verdict
The clearest difference is monetization model: Debt System at free against Isal's freemium. Debt System also leads on ratings volume (163 vs 2). Isal's advantage is update cadence (every 5 days vs every 3 weeks) and rating (5.0 vs 4.8). On price, review sentiment, ads 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. Debt System sells 9 one-off in-app purchases and Isal sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Isal holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Debt System has 163 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Debt System ships an update every 3 weeks, Isal every 5 days. Both last shipped on October 24, 2026.
