I have all the Affinity apps (Photo, Designer and Publisher) and they are all excellent alternatives to the Adobe equivalents (Photoshop, Illustrator and InDesign). Unlike Adobe apps, Affinity apps are not subscription-based. Note that the Affinity apps are feature rich and produce professional results, but they are not designed to mimic all the tools in Adobe apps i.e. Affinity apps are not feature-equal to Adobe (by design). If you are designing YouTube thumbnails or posters, then the Affinity apps will be more than capable. There are also a fairly large number of tutorials on the Affinity apps, particularly on YouTube. And if you ever get stuck trying to achieve something in Affinity Photo, there's enough overlap between Photo and Photoshop that you can usually follow a Photoshop tutorial and recreate it in Photo. The Affinity website has a showcase of work made in their apps: https://affinityspotlight.com/ https://affinityspotlight.com/ If Affinity feels like overkill for you needs, an online template service like canva.com might be worth a look. Canva have ready-designed templates you can modify (including posters and YouTube thumbnails). They have a free tier and paid subscription tier.
