No longer free

I've used the app for all of my 5 kids and it's fine. I normally just like to look it up periodically to see what milestones my baby should be hitting, but I don't need to pay for that feature. It's unfortunate that after years of having this for free they'd pull my free subscription. It's not worth the money in my opinion.

No free version anymore

There is no option for a free version any longer. You have to have an account and pay to use this app. I’m now deleting this app and going with a different one as the information is all the same.

Update: the developers response was not helpful and did not address my concerns on the fact that this app is now subscription based instead of free. Parents are already nickel and dimed on everything concerning our children. Now we have an app that used to be free or have a one time fee making a cash grab for a monthly subscription. My advice to others, don’t subscribe to this app as you can find the information online, or buy their book at a used bookstore and get the information for much less than what they are now charging to use their app.

Money hungry

I originally paid $5 to access this app when my first child was born. Now, with my second, they recently switched to a monthly subscription model that’s $5 PER MONTH. You would THINK because I already paid for the app, I’d be grandfathered in to the original pricing, but, no. Bad business model.

Paid app changed licensing on users

This app used to be purchasable for $6. Anyone who purchased it was booted off of the app without being able to use it anymore with the option to download your data or drop your data. I no longer recommend this app.

Disappointed with the payment change

I purchased this app years ago for my first baby. It was always sold as a once off payment to use the app as you wish. Now, when I tried to check how my recent baby is going with their leaps, I have to sign up and pay monthly…. Very very poor especially when I have already purchased the app! Won’t be recommending this app anymore. I have them 2 starts because the app itself is handy. But integrity is everything and if I’ve already paid for the app, why make me now subscribe.
