Take the guess work out of parenting and discover the joy of knowing what your baby has to say before she can talk! One of the most fundamental human desires is to be understood - help your baby communicate by teaching her baby sign language. This app includes approx. 340 signs and over 1 hour of real life video demonstrations! The friendly presenters in the 'Baby Sign Language Dictionary' app will help you to learn to sign with your baby in an engaging and enjoyable way. The keyword signs demonstrated in this video dictionary are based on American Sign Language (ASL). All signs have been carefully selected for their ease of use, helpfulness to carers and appropriateness for baby's interests and daily routine. Each sign has a detailed video tutorial covering information such as: simple instructions on how to perform the sign, clever tips to help you remember the sign and practical suggestions on how to introduce the sign to your baby. The signs are also organized into categories such as: action words, animals, daily routines, feelings and emotions, food, manners and behavior, and nature – all of which are arranged alphabetically for quick and easy searching. To test your baby signing knowledge, the app also comes with a fun interactive video quiz that will help you learn and remember the signs. You can also mark signs as part of your favorites list. Other key features: • high quality graphics and videos optimized for viewing on Retina displays. • optional setting to allow continuous play through of all signs in a category. • swipe through the signs in a category without returning to the menu. • optional setting to view a simplified demonstration for a sign rather than the complete tutorial. This app makes the perfect parent's companion to the popular 'Baby Sign and Learn' animated apps (also available on the App Store). Featuring gentle guidance and practical advice, this app has been designed to help make teaching your baby to sign as easy as waving “bye-bye”!

Verdict

The call

The clearest difference is price: Baby Sign Dictionary ASL at $2.99 against ASL Dictionary Sign Language's $7.99. ASL Dictionary Sign Language's advantage is update cadence (every 4 months vs every 15 months) and rating (4.7 vs 4.5). On review sentiment, ads, in-app purchases and chart position there is nothing between them.

Baby Sign Dictionary ASL costs $2.99 and ASL Dictionary Sign Language $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

ASL Dictionary Sign Language holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: ASL Dictionary Sign Language has 2K ratings behind it against 233, so its average is the more settled of the two. Written reviews complicate that: 88% of Baby Sign Dictionary ASL's written reviews are positive against 86% of ASL Dictionary Sign Language's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Baby Sign Dictionary ASL ships an update every 15 months, ASL Dictionary Sign Language every 4 months. The most recent releases landed on September 19, 2026 and September 24, 2026 respectively.
