Briefly put, no: because Fairo for web is not a desktop app, but a web interface, so it doesn’t need instalation. You just need to log in using your email address. And if you already have the Fairo mobile app, it’s the same story – no need to install anything extra, just log in from your browser and see all your company data there.
Not at all – you have the freedom to choose what device suits you best. If you prefer to work from your laptop – it’s enough to register to Fairo for Web. If you’d rather have everything at hand even when you’re not near your laptop – you can download the mobile app and enjoy the flexibility.
