  I have loved the Constriction Master since they were introduced. Before cellphones you would find one in my bags at all times.

  HAVE TO PAY TO USE

• ★★★★★chuchoseco

  Comprar

  Yo ya la tenía comprada en Android porque no se me pasó para el iPhone si es el mismo correo?

• ★★★★★Nickfly1

  Overpriced

  Great app but not worth $30 a year

• ★★★★★banson.youngs

  Subscription calculator!?

  The 5 star reviews have got to be fake accounts! There’s no way people are happily paying yearly subscriptions for a construction calculator app. Great product being taken over by greedy business practices. You don’t even deserve the 1 star I had to give you to post this!

  I have used this calculator since 1999. I taught it for nine years at Salt Lake community college and UVSC. I love it.
