While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

How this company uses Trustpilot
See how their reviews and ratings are sourced, scored, and moderated.
A poorly designed app with almost no functionality or useful features. It provides less information than a single Excel sheet, and on top of that, it barely works — half the time it doesn’t function at all, and the other half it crashes. I contacted them multiple times but they don't care. An intern could design a better app. The worst app ever
A headache overall!!!
The calculations for the amounts are VERY shady, the website doesn't work, they are very much unreachable, and when you eventually reach them they say "well, its not our fault". They charge you extra for nothing, overall VERY bad experience.
The calculation of 2024 arrived in June 2025… everything is too slow and too expensive
