Verdict

The call

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.
