iPen 2 Production Schedule - iPad model


Dear Backer,

As we near mass production, our confidence in our product grows. Our hard work for these past 23 months has resulted in an outstanding stylus, far superior to the competition. While a design that fit the iPad case would have been ideal, we are pleased that our revised design allows for superior performance. Due to the Chinese New Year, we will review our T0 sample (iPad model) this week, and expect to have the T1 sample ready by February 26th. The following are our main production milestones:

  • February 19th SMT/PCBA Testing (revised version) 
  • February 24th Engineering Run Assembly/Test
  • February 27th - March 13th MFi Review I
  • March 14th - March 17th Possible Revision after MFi Review I
  • March 26th Production Run Assembly/Test
  • April 1st – April 8th MFi Review II
  • April 9th – April 11th Mass Production

We are actively mitigating risks inherent to mass production. Cregle is now building several customized testing tools and software to control quality in the assembly line. We’ve learned that each receiver must be manually adjusted in the assembly line, due to the precise angle necessary for the sensors on the receiver, and we are taking steps to make mass production as smooth as possible.

The iPen 2 will release with 2 additional apps: Calibrator and Showroom. The calibrator app will allow users to calibrate the iPen 2 and configure other settings; and with Showroom, users can try iPen 2 with potential features that are available to app developers to integrate through our public SDK. The following videos are taken with our engineering sample. We will release more videos when our T1 sample is ready.

The 30-pin Model & Refund Update

We understand the delay has raised doubts in the project. We appreciate your continued support. It has enabled us to surmount nearly every obstacle put in our path. Regretfully, we cannot build the 30-pin model due to insufficient funds. We wish it were as simple as just replacing the lightning connector with the 30-pin connector, but such a design would cost an additional $100K that could not be recouped in product sales.

For those backers requesting a refund, please give us a few more weeks to process your refund as all our funds are currently tied up in mass production. We appreciate your patience.

We are excited that the iPen 2 performance is far superior to that of our competitors. Its accuracy, palm rejection, and ability to write on non-touch screens validate our efforts and your support. We’re pleased to report that development for the iMac model is progressing nicely. Your patience will pay off. Thank you for continuing to give us the time to focus our attention on finishing what we started, and bringing this product to the world.

Warm Regards,


George T. Filak, James Daggett, and 3 more people like this update.

      One needs really patience, but I hope, the waiting was worth it when the iPen 2 will be finally delivered ...

      I see from the comments here that there are various backers asking about ...

      1) How to get a refund?

      2) If the 30-pin version was ordered, but since you won't be making the 30-pin version, does this mean the backer automatically gets the Lightning version?

      3) ...

      We would all appreciate if you could post clear answers to at least the two questions above. You need to have a clearly stated policy on those two items since I'm certain a fair number of backers have the same concerns.

      Please come right out and clarify!

      How do I request the refund for the 30 pin device that is no longer being shipped?

    4. Johann Pongratz on

      Hi, will the lightning model fit to iPad 4 and Air?
      Thanks, Johann

      Thanks, Hsiu. That's what I guess so as well. I agree your points.

      The good thing about the wireless model is that the user can fit the model on top side of your ipad. The plug side of the ipad can be left for more flexible utilization.

      Hi Gary. What cregle say about wireless model is communicating through Bluetooth or wifi. It does not come with a male plug to the ipad side. A wireless model is still under design I guess. The sampling frequency would be a concern for the user if the reaction rate are faster enough to catch our pen movements over wireless. But I think it won't be much a problem as Bluetooth is a quite mature tech now.

      What's the meaning of "wait for wireless model" in your reply to Bryce?

      Ditto. I have a 30-pin iPad and don't plan to upgrade for a while. Instructions for refund?

      Howard zelaznik on 30 pin model. I ordered the 30 pin. If I do nothing, you will send me the lightening connector version. Correct??? If so, I will just sit tight.

      Dear Cregle,

      Since you are not making a 30 pin connection which is what I need. I do have an iMAC and want to know what I need to do if anything. Please respond.

      Thank you,

      Where do you stand with the iMac model? Will it still be compatible with the thicker 2011 iMacs?

    17. Cregle Inc. 2-time creator on

      @Bryce: You can change to iPad 4/Air, wait for wireless model or request refund.

      What do we do if we selected the 30-pin model in the survey?
