Verdict

The call

The clearest difference is rating: Kalq at 5.0 against TesDisplay's 2.4. Kalq also leads on in-app purchases (none vs 1) and update cadence (daily vs every 2 months). TesDisplay's advantage is ratings volume (48 vs 1) and iOS requirement (15.0 vs 17.6). On price, ads and device support there is nothing between them.
