VIP gives you expected fertile days (not worked for me)
Gives you a green traffic light when it thinks your fertiles (got a light for 3 days but negs on opks)
Think it tells you % chance of being pg after ov.
Give you hints and tips all through the month but it's all things we read on here.
You can overlay your charts.
You can compare your charts to others that ov'd around the same time, had positive pg tests, had af, ect.
The free one does none of the bove.
You can chart, detects ov, pop notes in.
Depends what your looking for. I paid for 3 months the start of this month and TBH at the moment its doing nothing for me than the free one! I'm no better off with any of it yet.
Start with the freebie babe. At the moment you dont want to pay anyway with your cycles how they are. Your be throwing your money away.
