### 1/5 — $8 per month after one week trial

*2024-07-12*

I didn’t bother😂

**Developer response:** Dear Customer, Thank you for your feedback.
We will use your input to help guide our future development.
Best regards.

### 1/5 — Pay to use only…

*2021-09-22*

Just let people know that this is subscription only… happy to pay one time fee, but subscription? No thank you! Don’t even want to take a look in free trial.

**Developer response:** Dear Customer,
Thank you for your feedback.
As you said, this app is a subscription model. However, the reason we chose the subscription model is to lower your costs even more. Please activate your subscription only for as long as you need it. We think it costs less than buying other similar software.
This software was created to solve the problem that students and small laboratories cannot buy similar very expensive software.
We will continue to improve for the development of science.
Best regards.
