### 5/5 — Honestly helpful

*2026-08-26, version 3.1.5*

I’m a real person I just downloaded this today I like it I’m learning a lot

### 5/5 — Get it!

*2026-08-24, version 3.1.5*

Yep it’s for real!

### 5/5 — Great.

*2026-08-23, version 3.1.5*

Very helpful for a beginner

### 5/5 — Good, but vibrations are anoying

*2026-08-23, version 3.1.5*

I like the app so far, but the vibrations are anoying af and I cant seem to be able to turn them off. Would love the option to do so.

### 3/5 — Okay

*2026-08-17, version 3.1.5*

Es una buena app pero necesita más herramientas de entretenimiento para el precio que cuesta! La app es muy básica, debería ofrecer como enseñar a contar también

### 4/5 — Great App

*2026-08-12, version 3.1.4*

Great app only 4 stars because I think it would be even better if in the core practice mode you click on a card to switch it. I can stare at the tables all day long but I wish I could see in real time when something could switch from Hit, Stand, Double, Split depending on if the dealer would’ve had this card rather than the other or vice versa.

### 1/5 — Warning!

*2026-08-11, version 3.1.4*

Don’t sign up for the free trail. Even if you cancel they will bill you anyways  and Apple leaves you with no recourse.

Edit: Apple denied my refund request without explanation. BJT is shady. Use someone else.

### 4/5 — Muscle Memory Black Jack

*2026-07-31, version 3.1.4*

Pretty practical, the sub is not too overwhelming.. most folks spend a lot more on trainers. I enjoy the feature for weak hands practice. This doesn’t turn you into a complete player.. but the practice is simple and clear to get familiar with basic strategy.

### 1/5 — Beware of sneaky free trial!

*2026-07-25, version 3.1.4*

I signed up for a free trial and got charged when I cancelled. Beware!

### 5/5 — Great trainer for basic strategy.

*2026-07-11, version 3.1.4*

I was using the black Jack apprentice program for many years and really enjoy the buttons instead of jesters for sure. The charts are very clean and the simulations really focus on hands that have unique strategies like 12 and tens for example. I am so pleased and it’s not glitchy
