Verdict

The call

The clearest difference is rating: Study Notes ABA at 4.9 against TallyFlex's 4.3. Study Notes ABA also leads on review sentiment (89% vs 64%) and ratings volume (3.6K vs 87). TallyFlex's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 10 days vs every 5 weeks). On price, ads, in-app purchases and device support there is nothing between them.
