This one is really good :) it's called N+OTES and I don't know if it's just me and my OCD but i like to have my stuff organised. I made a file and in that file you can put other things in it. Like I put all my thinspo and tips In it so if anyone goes on my phone they won't be able to find it in my regular notes/photos etc. 
You can add me... That's my address thingy... Idk how it works but...

Yeah you probably already know what myfitnesspal is but if you don't it's something so you can literary track all the calories you eat/exercise/weight loss and you can add people too...:) it works too...
I personally really like this one... It's called foodiet and what you do is type in a food/brand and it gives you a grade of how good it is for weight loss. There's also a restaurant section and it's pretty much got everything you need... Yeah one of my favourites :)
This one's good if you fast a lot. It lets you track your fasts and weight... Pretty self explanatory...
Last one...
Okay I hope you like those apps and if you know of anymore please comment :)
Now to leave you with some thinspo...
