Verdict

The call

The clearest difference is ads: Alpha Discovery at none against CDL Practice Test® 2026's shown. Alpha Discovery also leads on iOS requirement (15.0 vs 17.6). CDL Practice Test® 2026's advantage is update cadence (weekly vs every 5 months). On price, in-app purchases and device support there is nothing between them.
