## Most critical reviews (10 lowest-rated)

### 1/5 — E65S GBW

*2026-07-20*

App is terrible. Honestly, it’s janky, and doesn’t perform any task well. I can’t even update grinder through app. I just use the dial on grinder. Even now with the update it doesn’t show my grinder, it shows the e64ws photo and standby doesn’t work anymore. There’s no reason to use the app for anything. Let alone trying to dial in a bean. It’s laughable, unfortunately, because I love my mahlkonig grinder and really wanted this to be as phenomenal.

### 1/5 — German software

*2026-04-25*

Totally incompetent onboarding. Cannot set password

### 1/5 — Returned the accompanying grinder

*2026-04-20*

The app is so bad that I returned the E64WS grinder that it supposedly worked with. The app might be good for updating the firmware in the sync scale, but not for adjusting and dialing in an espresso shot. I really wanted this to work.

### 1/5 — E64 WS Implementation Incomplete

*2026-03-19*

Can’t create recipes for E64 WS grinder.

### 1/5 — Why?!?!

*2026-02-16*

Why is this app so bad?! How? From a leading brand in the coffee industry. How is this even a thing?! So so so disappointing. Absolutely rubbish

### 1/5 — Same look nothing changed

*2026-02-05*

After the “update” still the same old app. If you are serious about getting into the home market you have to rethink your apps and user experience.

### 1/5 — App doesn’t connect to device

*2026-01-11*

App doesn’t work and no support

### 1/5 — Doesn’t work with e64ws

*2026-01-08*

Even though the app claims to work with e64ws, it doesn’t

### 1/5 — Doesn’t work for E64 WS

*2025-12-02*

Just purchased an E64 WS, and I wasn’t able to onboard it to the app even though it was claimed to be supported. Grinder is decent but this app just doesn’t work for it.

### 2/5 — Doesn’t do much

*2026-05-23*

As most report the app is thin on everything. The lack.of updates (now 3 months) says it all...
