Can't register The key sent was wrong message pop's up. No response from the developer. It's waist of money. I'm recommend to ban this apps developer from Google market.

Francesco Auciello

Poor support Will not let me use app after registering with another app from the same creator. Spent money on something I could have used for school, instead waisted. Really, it takes 7+ months to reply to us, 7+ plus months?!

Ronnie Thomas Varghese

Can't log in I'd bought one other app from faadoo and logged in to that but when I bought the second one and tried logging in, it wouldn't let me. Also, it asks for a password where there is no field to enter a password. I went to the website to reset my "password" (more like create an account and password) but never got an email with the changed password or account info! The app makers should fix this else I want my money back! I guess if I don't hear from the app makers, I can put in a complaint to the Play Store.

Apiline Falevai

How many times Do I need to register and how many email addresses?????? I purchased 15 apps courses on faadooengineers and when I opened 1 and I was required to register with usename and email address and I did. When I opened the second one I was required to do the same and I tried to register but when I did, it said I need new email address as mine has been used, which mean that I had used it for the 1st app I registered for, my problem is that I purchased the apps and now I need 15 email addresses to use the apps!? Please help me as I am desperate for some assistance. Otherwise I would like a refund!

FPowerLib (Fluid Power Library) is an application providing a quick reference library to the most used hydraulic and pneumatic components. These components are organized as i) basic symbols, ii) control elements, iii) conversion elements, iv) storage elements, v) regulation elements, vi) equations. In the first five sections the user has access to a description of the most common fluid power elements, along with its normalized symbol. Section vi) allows the user to perform basic calculations involving several topics like forces and velocities of cylinders, energy stored in hydraulic accumulators, flow in hydraulic pumps and flow in pneumatic and hydraulic valves. FPowerLib is therefore a useful tool to all who work or study Fluid Power systems!
