I recommend DesignDoll! There is a premium version but the basic version has enough features that you can get by just fine without needing to pay for premium. It's not preset poses, you can pose the model how you see fit. You can rotate around, zoom in & out, so on so forth. Theres no save function, but you can export shots of your poses as jpg.
You can also adjust the default models proportions and heights! The model has very natural constraints so the poses are as close to what an actual human can manage.
