User Reviews

User feedback is largely negative. The main drawbacks are reliability and performance issues: the app frequently crashes or fails to complete an upscaling task, and render times are extremely slow. Some reviewers report service drops during rendering and bugs with importing longer files. A minority say the output can be satisfactory or very good when it runs, with a desktop-like look noted post-fix. Overall, instability and long processing times outweigh the few positive notes.

Pros

Delivers usable results when it works
Meets basic upscaling needs for some users
Some reviews describe the output as very good

Cons

Extremely slow processing and long render times (e.g., 30 minutes for 1% or 15 minutes for 10 seconds)
Frequent crashes or not working at all
Rendering drops / service interruptions during upscaling
Import prompts that interrupt and prevent completion for longer clips
Usability gaps and confusing navigation related to app-store prompts
