# PDF Pro vs PDF Highlighter

The clearest difference is review sentiment: PDF Pro at 60% against PDF Highlighter's 0%. PDF Pro also leads on rating (4.7 vs 3.0) and update cadence (every 2 months vs every 95 months). PDF Highlighter's advantage is monetization model (free vs subscription). On price, ads, in-app purchases and device support there is nothing between them.
