### 1/5 — Just one thing

*2025-10-29*

This app does offer a three day trial with a catch that it says you can cancel any time yet there’s no option on the app to cancel the trial so you will be charged for the subscription the day before the trial ends so my question is how can I cancel this trial before I get charged for a subscription that I don’t want?

### 1/5 — No way to cancel

*2025-09-14*

There is no way to cancel. No way to see if it’s been charged.
