DEAFinition South African Sign Language app will allow you to learn specific signs to better communicate with Deaf friends, colleagues, or customers. The DEAFinition South African Sign Language app will allow the user to browse words, look up specific words and request a word if it’s not available on the app. The Deaf community is one of the most marginalized groups in South Africa. Because they cannot communicate freely with the hearing world, they are often regarded as incompetent or not intelligent, and not fit to be employed. This is far from the truth! DEAFinition is a non-profit company providing a range of services and funding opportunities to promote equal access for the Deaf community. The DEAFinition SASL App offers reference videos and material for the official sign language used by Deaf people in South Africa.

Verdict
The clearest difference is rating: SASL DEAFinition at 5.0 against NZSL Dictionary's 4.0. SASL DEAFinition also leads on update cadence (every 2 months vs every 7 months). NZSL Dictionary's advantage is review sentiment (80% vs 67%) and ratings volume (9 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SASL DEAFinition holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 9 and 2 respectively. Written reviews complicate that: 80% of NZSL Dictionary's written reviews are positive against 67% of SASL DEAFinition's, so the app with the better star average is not the one people write more warmly about.
