## Review summary

Reviews are mixed. Many praise the app when it functions (positive terms like excellent, nice, good), but a large portion complain about excessive ads and frequent non-functionality (USB not read, device compatibility issues, or a stuck welcome screen).

Overall, the app shows potential but reliability and user experience are serious concerns.
