First, look at all the reviews: The 5-star reviews stopped a year ago when they changed their business model.
Shocking that basically the only thing you can do with TrimandCutVideoEditor without signing up to their subscription is browse your videos.
Then they want you to pay a weekly (!) subscription to use their one-feature app.
If I use it for 5 years, that is $2.99 x 52 weeks x 5 years = $777.4 + tax.
These people (Bending Spoons) are trying to publish as many apps as possible (for instance they own multiple similar video editing apps), charge as much as possible, and confuse users into over-paying. This is basically like a software slumlord.
To their "credit" they are very open about this. One of the cofounders proudly says on the company webpage: "I'm not in TrimandCutVideoEditor business, I'm in the empire business." How to bilk customers in other words, and establish monopolies.
I have been paying for shareware since the 90's, and I am a software engineer myself. Software is valuable, should be valued, but their business model offends me.
Update: In response to the developer's form response inviting suggestions, here is my suggestion: Price TrimandCutVideoEditor reasonably. Try $15/year.
