We make Ziggy, so we're biased. We've described every app as fairly as we can and checked each one's features in November 2026. If something has changed, email support@ziggyasl.com and we'll update this page.

Where Ziggy is stronger
- It tells you what to learn next. You don't have to plan your own path.
- It brings signs back. Spaced review and drills turn signs you've seen into signs you know.
- It keeps you coming back. Streaks and small wins make a few minutes a day easy.
- Free web tools. A free dictionary with notes on how each sign is made, beginner guides, and a sign-your-name tool on ziggyasl.com.
Where The ASL App is stronger
- Made by Deaf people. The content comes from the Deaf community.
- A bigger vocabulary. Themed bundles like dining, sports, and emergencies.
- Pay once. Free starter bundles, then one purchase unlocks everything, with no subscription.
