Since many Macs have a retina screen, please create the banners at 200% scale:
• 600x500px (300x250px on regular screens)
• 1456x180px (728x90px)
• 600x1200px (300x600px)
Banners must contain:
• app icon (see attachment)
• productivity chart (see attachment)
• large title: "Are you productive enough?"
• smaller text: "Discover how you spend your time on Mac with Qbserve"
• "Download" button
Optionally: remove "with Qbserve" from the smaller text and make a "Get Qbserve" button instead of the "Download" button. You can also add or remove chart columns to get a better look.
