Memory is all that remains of a person. As long as the deceased is remembered, he is considered alive. The sages of our Blessed Memory say (Tractates Berakhot 18A and 18B): "The righteous are called living even after their death." "Kaddish Lanetzach" is a unique opportunity to preserve the memory of our dear friends and relatives. Our application will help keep this memory at a decent level. Appreciate the memory of our ancestors!

Verdict
The clearest difference is rating: Kadish at 5.0 against OU Kosher's 4.1. Kadish also leads on review sentiment (100% vs 68%) and monetization model (free vs ad-supported). OU Kosher's advantage is ratings volume (15 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Kadish holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: OU Kosher has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 68% of OU Kosher's written reviews are positive against 100% of Kadish's.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 23, 2026 and September 29, 2026 respectively.
