My fingess pal app/ calorie intake?

I've recently been trying to use my finess pal app on my iPhone as a food diary and I've noticed it only allows me to have 1300 calories a day but I was told that's dangerous. Is this try should I be consuming more? On my good days I eat 5 times a day and I find that I don't use all of my calories. Is this bad?

Depend your age, activity level, height and weight…

But 1300 calories is generally not dangerous for girls under 200 lbs who aren't too active. (Not enough for teens, very heavy and active girls)
