### 2/5 — App is great! The ads have inappropriate content

*2026-08-11*

I love the app! I work with special needs kids and sometimes I need to look up a sign. But today I opened the app and the ad at the bottom had inappropriate content for my therapy session and I had a kid and a parent in my room! I quickly turned it off and did something else. I get bedding the ads but that was ridiculous! I think it was a temu add.

### 5/5 — Simple in the best way

*2026-01-29*

I'd mostly been using websites like Lifeprint and Handspeak as dictionaries since they're very reliable, but I was so happy to find this app because it is soooo much easier to navigate on mobile than those places. Because it's just grabbing the videos, it's also super fast to load and is such a great way to quickly pull up signs whenever I need them. 

Also very pleased that the app size is so small! Love a native app!

### 5/5 — Great!

*2026-01-21, version 2.0*

What an excellent resource. Thanks very much :)

### 2/5 — Not great

*2026-01-18, version 2.0*

I don’t really like that I have to go to the search bar to search for the sign language, I just want to take lessons.

### 5/5 — Exactly what I was looking for

*2025-11-19*

A very convenient, simple app, which shows you multiple videos of people signing whatever sign you searched. This is exactly what I was looking for, as a casual learner of ASL, mostly for nursery rhymes for my baby.

### 3/5 — Vids do not play

*2025-02-05, version 2.0*

Tried several selections, no videos or images.

### 4/5 — Perfect ASL Dictionary App, Just Needs a Playback Option

*2024-12-14, version 2.0*

I love this app! It’s exactly what I was looking for. This isn’t an app that teaches you ASL step-by-step but rather a dictionary-style tool where you can look up specific words. Think of it as an ASL dictionary rather than a learning platform like Duolingo. The only reason I’m giving it four stars instead of five is because of the video speed. I wish there was a playback option to slow down the videos, similar to YouTube or TikTok. Other than that, this app is absolutely amazing!

### 5/5 — Improved

*2024-10-16*

Thank you for the update! I have used this app for years, but was frustrated because I couldn’t see all the video. It is so much better now. It has been very helpful in adding to my ASL vocabulary.

### 5/5 — Great app to help you learn ASL

*2024-09-18*

I down-loaded the app and started using it right away, but ran into some formatting problems and was having difficulty viewing signed examples that were presented, since the view of them was being blocked. I sent a message and Daniel responded quickly and the issue was resolved quickly.
Thanks for proving this useful tool.

### 4/5 — A great resource!

*2024-08-19*

I’ve been using this app for years as a hearing person who wants to incorporate as many real ASL signs into our homeschool learning as I can. It’s incredibly helpful and well-organized. Unfortunately, at some point recently the video player updated in an unhelpful way. Now, to play the video, you have to touch the app, and the “play” triangle sign covers the center of the video for a few seconds. Since the sign videos are only a few seconds long, this often covers up the signers hands for the whole video. In the past, the controls for the video were at the bottom of the screen so this didn’t happen. Can the developer/ designer adjust this?
