### 1/5 — Expensive scale cheap app

*2026-06-17, version 2.0.49*

It’s unfortunate that a company produces a scale of this price point and quality and puts very minimal effort into the software needed to fully unlock the potential of the product.

### 5/5 — 软件不错，就是界面很古老

*2025-08-23*

连接后体验还可以，好像很久没更新了

### 1/5 — Update broke key feature

*2025-05-21, version 2.0.44*

Update 5/21/2025: another update is even worse... now none of the saved images shows!!! 😡 Please fix it ASAP!

Latest update from May 2025 2.0.43 doesn't shows old images for individual shots. Please fix it asap!

### 1/5 — 安定性なし。使い物にならない

*2025-04-27*

スタートしてもスタートしなかったりクラッシュしたり、UIも見にくく、出力するcsvに入力した情報の全てが含まれてないなど、実用的に使おうとしても障壁が多すぎて使い物にならない。スケール自体はいいものだけに、かなり勿体無い。アプリの使い勝手とメンテナンス面で他社製のほうが良いかもしれません。

### 1/5 — Crashes, no way to edit water and update profile picture does not work

*2024-12-21, version 2.0.37*

The app constantly crashes and no way to edit water. Which makes it useless. The idea is amazing but implementation so bad.

### 2/5 — Frustrating App

*2024-11-29*

I can’t get this to work properly, sometimes I can add a photo from my library other times I can’t. Don’t even get me started on trying to edit a picture. Please fix the issues with Brewmaster. iPhone 12 Pro, latest iOS18.

### 1/5 — アプリが頻繁にクラッシュします

*2023-11-11*

acaia pearlを購入しました。スケールの精度にはとても満足しています！
しかし、アプリはクラッシュしてログが記録できないことがよくあり残念です…

### 1/5 — Unterirdisch

*2023-05-28*

unterirdisch(!!) für den Preis der Waage. Bluetoothverbindung ist reine Lotterie. UX ist in der gesamten App ein Fremdwort. Die Anleitung zur Waage missverständlich und unvollständig. Daten eines shots werden nicht gespeichert wenn man übersieht noch save zu drücken. Autostop gibt es nicht. Die Waage ist übrigens nicht genauer als eine für 30Euro ... nur eben das design ist schöner. Ich habe das Gerät zurück geschickt. Acaia ist für mich tabu bei so einer Ignoranz gegnüber dem Kunden

### 2/5 — Crashes very often

*2023-01-21, version 2.0.37*

App crashes so frequently its almost useless. Please reach out to me if you would like a professional app thats as nice as the lunar scale.

### 1/5 — Lousy user experience

*2022-12-01, version 2.0.37*

Whoever designed the app may have some basic experience with graphic design, but definitely not with user interface design. Frankly all I wanted was to see what my pour rates were on a graph to practice pouring at 6-8 g/s. It was such a p.i.t.a. to do this. (((and that text soooo tiny)))

Really not even a diagnostic or basic screen just showing scale data like that BIG somewhere?

Has programming API been made available or documented? I’ll write my own.
