Verdict
The clearest difference is in-app purchases: ADI Study Watch at none against ThoughtBeam's 4. ADI Study Watch also leads on iOS requirement (12.1 vs 16.4). ThoughtBeam's advantage is update cadence (fortnightly vs every 5 months). On price, ads and device support there is nothing between them.
