How migration works

  1. 1

    Verify your web license

    Enter the license ID and password you currently use so we can confirm that the license is eligible.

  2. 2

    Receive a migration coupon

    After verification, one coupon will be issued to unlock Pro in the iPhone app.

  3. 3

    Redeem it on the App Store

    Follow the on-screen instructions to redeem the coupon and enable Pro in the iPhone app.

Verify your license

Enter your web account details.

Your ID and password are used only to verify the license. k-trick does not store your password.

Migration is not open yet.

The iPhone app is now available, and we are preparing to open migration for web-version users. Until then, you can continue using the web version as usual.

Before you begin

One coupon per license

A web license cannot be used to issue multiple coupons. Keep the coupon in a safe place after it is issued.

Check your Apple Account

Redeem the coupon using the Apple Account you normally use on the iPhone where Force Calculator will be installed.

If you need help

If your license cannot be verified or the coupon cannot be redeemed, contact support@k-trick.com.
