How to Mark Work Days on iPhone Calendar (tutorial)

Why It Doesn't Work

• The iPhone screen is too small to clearly show the calendar app.
• The text 'MARK WORK DAYS' is small and lacks visual impact.
• The overall image is dark and lacks vibrant, attention-grabbing colors.
• The thumbnail repeats the title without adding new information or intrigue.
• The composition feels cluttered with the phone, calendar icon, and text all competing.
