Most-Requested Missing Features

Features users are literally asking for in their reviews, ranked by demand.

#1: Accurate ASL grammar and sentence structure

High Demand
"This app has the right idea, and most of the actual signs are accurate. Grammar on the other hand is completely incorrect"
"When I do put in a sentence, it's not translated into ASL sentence structure or it will leave out pertinent signs"

#2: Consultation with Deaf ASL experts

High Demand
"Its clear that the developer team did not consult with Deaf ASL experts on this design"
"Please don't use this as a translator or to learn ASL"

#3: Variable speed control that works properly

Medium Demand
"This app is great and all but you should make more potions for speed or at least where is doesnt delete the text after you put it in"
"I like this app because i'm learning sign language and makes it easier to learn especially because there's a slow version if you don't catch on as easily (me)"

#4: Additional sign language support (Spanish SSL, etc.)

Medium Demand
"So when I first download this app, I was really excited to use it but then when I found out it didn't support Spanish so I deleted it because I wanted to learn SSL (Spanish Sign Languge) you need to add more languages like Spanish"

Build Recommendations

Prioritized actions based on user demand and market opportunity.

Partner with Deaf ASL experts from day one for linguistic accuracy

The #1 complaint is incorrect signs and lack of deaf community involvement. Building with cultural and linguistic authenticity is non-negotiable for credibility and effectiveness.

Implement true ASL grammar engine, not word-for-word English translation

22% of reviews cite PSE/SEE usage instead of ASL. Users recognize the difference and want authentic ASL sentence structure, which requires AI/NLP that understands ASL as its own language.

Build comprehensive sign library to eliminate fingerspelling overuse

25% of reviews complain about excessive fingerspelling for common words that have established signs. A robust sign database with proper signs for common vocabulary is essential.

Focus on rock-solid technical reliability before feature expansion

28% report crashes and freezing. Performance issues prevent users from even experiencing the product. Prioritize stability, fast loading, and reliable text input/translation flow.

Create transparent accuracy rating system with community feedback loop

Users are worried about which signs are wrong and can't trust the app. Allow Deaf users to flag incorrect signs, show confidence scores, and demonstrate continuous improvement with community input.
