Verdict

The call

The clearest difference is in-app purchases: TOKAI App at none against Acrobat Reader's 18. TOKAI App also leads on iOS requirement (13.0 vs 18.3). Acrobat Reader's advantage is update cadence (every 9 days vs every 3 weeks) and chart position (#2 vs unranked). On price, ads and device support there is nothing between them.
