Is using my iphone good enough to film youtube videos?

So i've started my youtube channel this year in late February, and so far i have about 5 subscribers and over 100 views, and i use the back of my iphone 5C to film with the lock on, i feel like the qauilty of the camera inst that good so maybe that why people are not really subscribing? I don't really have the money to get one of those DSLC cameras right now, is there a camera that i can use that is cheap enough for me to buy at the moment that i can use to film with? Maybe with a view finder, or is there something i can do in the settings of my iphone that can make the videos come out more clearer?

What you are filming is light. Make sure you have plenty of it.

Oh yeah!
Iphone camera's are AMAZING QUALITY and are actually better than some cameras. As long as you have nice lighting it will look beautiful <3

Iphone cameras are good so your videos are probably fine. But anyway, you can subscribe to my channel! This is the link: https://www.youtube.com/...ETnGe1gKXw

A lot of people do it, it should be fine. Just make sure you film horizontally, a lot of people freak out when there are black bars.
