Verdict
The clearest difference is rating: LAB Reads at 5.0 against Interchange's 4.3. LAB Reads also leads on in-app purchases (none vs 10) and iOS requirement (10.0 vs 12.2). Interchange's advantage is ratings volume (212 vs 1). On price, update cadence, ads and device support there is nothing between them.
