Con
👎 The free version relies heavily on ads and a strong paywall. Pop-ups and banners interrupt reading and basic tasks, and many useful features—advanced editing, high-quality OCR, and file conversion—are often locked behind a subscription. That monetization approach hurts casual users and makes the app feel more like a storefront than a utility.
👎 OCR and editing tools can be unreliable. Text recognition frequently struggles with complex layouts, nonstandard fonts, or handwritten notes, producing errors that need manual fixes. The in-app editor also lacks the precision and formatting controls of desktop PDF editors, limiting reliable text edits, advanced layout fixes, and professional document preparation.
👎 Performance and privacy issues can undermine confidence. The app may slow down or crash with very large or image-heavy PDFs, and background syncing can consume bandwidth. Privacy settings and permission requests are sometimes unclear, leaving users hesitant to store sensitive documents or trust cloud features without explicit control.
