Most User-Friendly Scanner Apps for Beginners

Hi all! I’m new to using scanner apps and need something that’s easy to use with a simple interface. What are the most user-friendly scanner apps out there? Are there any that are particularly good for beginners who might not be tech-savvy? I’m also curious about the quality of the scans—do these apps provide good results without much effort? How do the costs compare, and are there any hidden fees? I’d love to hear your recommendations!
