### 5/5 — Handy

*2026-07-19, version 1.54*

Great for those situations where you just can’t seem to figure it out

### 1/5 — Error messages

*2026-02-04, version 1.54*

So bummed about the quality. First its didnt even come close to the actual test. Now it wont even process it. Wack.

### 5/5 — Very accurate

*2025-12-22, version 1.54*

Super convenient for seeing THC percentage or if it even has THC¿

Easy to use

### 5/5 — Cool app

*2025-09-27, version 1.54*

Definitely a cool app. Helps me with my plants

### 2/5 — Disappointed

*2025-08-08, version 1.54*

My device measures every flower at 17%, never a variation despite different samples… was very excited but maybe the claims are just too good to be true.

### 1/5 — Rob

*2025-07-03, version 1.54*

After auto renewal app not working and can not get a response from HiGrade after almost a month! Had no problem taking my money!

### 5/5 — Great little lens.

*2025-05-13, version 1.54*

It’s way more accurate than I thought it would be. Have gone to dispensaries and gotten within 2%THC or less difference on almost all personal tests vs actual labs. Way to go guys, been using for several years now.

### 1/5 — 1 star

*2025-04-05, version 1.54*

I don’t normally give 1 star reviews but they give you 3 free questions to ask about your plant and they literally don’t work they never get back to you. This is a money grab
