Outstanding product 5 stars!!

We just got our finished book and I couldn’t love it more! ❤️👏🏼👏🏼👏🏼This app made it super easy to update and track our pregnancy journey from start to finish. The images supplied are adorable! You, Dad, and anyone else you choose can make journal entries and add photos/screenshots/emojis. You can also track mom’s health and symptoms optionally. The final product is an adorable diary of your pregnancy conception to birth. Do not be discouraged at check out that the dollar amount is listed in Japanese currency, this book is not expensive - just look up a currency calculator to figure out your total. Also, there are options for regular or deluxe. I just can’t say enough about how much we love our book. My only regret is I didn’t know about this with my other children! It’s adorable!

Pregnancy is not just for moms

We just started using this a week ago, and we love it so much!! I was so eager to find an app that not only tailored to me, but for dad as well. For us, dad is a HUGE part of the process and he wanted to be involved as much as possible! This helps us share the moments together, gives him tips and advice, gives us knowledge to know what’s going on, and we LOVE that we can journal together through this experience! We definitely plan on making our book once we are done. This app, by far, the best pregnancy app!

Cool, unique idea! That said...

The layout is a bit messy and difficult to navigate. It’s a Japanese app and the English translations are a bit off. There’s no option to switch from metric to imperial. If you want to track weight in pounds, you don’t have the option. If you're a Japanese speaker who uses the metric system, you’ll probably get more from this app. All this said, I love this idea! I haven’t found any other app that enables you to make a book based on your pregnancy rather than following the baby’s life. These are things I would love to share with my future child in addition to their milestones and photos outside of the womb. I think it’d be cool if it utilized a bit of Qeepsake’s features, where we get guided questions pertinent to our pregnancy texted and emailed to us.
