I used the free version to get a taste of the tools and what I really enjoyed was the ability to compare your channel to other channels when you visit them. I also liked finally seeing some metrics of my SEO but I was still having trouble word-smiting searchable tags because I would use up my daily searches within few minutes of using it. So after purchasing the Pro package at half price (because my channel was below 1000 subs), my tool box opened up and my SEO was improved significantly. The SEO optimizer is the reason why I bought it and will continue to use it. The other tools are okay at best. I tried using the Thumbnail maker but it wasn't meeting my design needs, I heard the free music playlist sometimes has issues with YouTube copyright issues, and the only use I get from the desktop app is the Health Report while all other functions are locked for higher paid levels. In a nutshell, TubeBuddy will not guarantee you to get views or subscribers but it will definitely give you a fighting chance by providing you with the tools you need to succeed.
