Verdict

The call

Text to Speech PDF Reader and PDF Scanner both sit at 4.5 stars, but that hides the real split: 100% of PDF Scanner's written reviews are positive against 44% of Text to Speech PDF Reader's. PDF Scanner also leads on monetization model (free with in-app purchases vs subscription). Text to Speech PDF Reader's advantage is update cadence (every 10 days vs every 2 months) and ratings volume (552 vs 45). On price, rating, ads and in-app purchases there is nothing between them.
