Verdict

The call

The clearest difference is monetization model: Read+ PDF Reader at free with in-app purchases against Text to Speech PDF Reader's subscription. Read+ PDF Reader also leads on review sentiment (67% vs 44%) and update cadence (every 3 days vs every 10 days). Text to Speech PDF Reader's advantage is ads (none vs shown) and ratings volume (552 vs 7). On price, rating, in-app purchases and device support there is nothing between them.
