Creative Cloud – Awesome creative apps from Adobe you can use for photography, design, video, websites, and more! Get started at just $9.99/mo. or upgrade to $49.99/mo. to get the entire collection of creative apps. The ones I personally use the most are Illustrator, Photoshop, InDesign, and Acrobat Pro.
Canva – A free, easy-to-use, powerful tool you can use to create your own social media graphics, flyers, business cards, brochures, book covers, and more! You can also upgrade to Canva for Work, if you’re looking for more features, for $12.95 a month.
Photoshop Express – Edit and customize your photos on your phone quickly and easily! You can also create collages, add watermarks and share quickly to multiple social media destinations with 1 click!
Snapseed – Another mobile app (and also on desktop) you can use for photo editing (tuning, cropping, rotating, adding filters, etc.)
