Has anyone used the Baby scope app for iphone? I downloaded it this morning and managed to find the baby's heartbeat for the first time! I am 22+2 today. The app is great, even though you have to pay for it, it's still a lot cheaper than buying a doppler and you can even record and share with your family/friends. They reccomend that you use it from week 30 as its easier to find the heartbeat but you can try earlier, my baby's heartbeat was 164 BPM today (counted over 15 seconds and multiplied by 4).
