    Completely unaware of what exactly the app does (just heard of it) and the nature of the project (free/open source/commercial) but I'd love to contribute if possible (electrical engineering + signal processing + machine learning background).

    Will send the data regardless :)

    Heh :)
    We are going to make logging your jumps more fancy than traditional paper log book :)

    One way - is recording all data like exit altitude, deploy altitude, etc automatically using your phone. Other way - to import data from you digital altimeter. That's why we need raw data from different altimeters.

    Welcome back!

    still admire the app in my Iphone8, got it 6 month or so ago. I’ve will get to use it first time in a few weeks, will be able to compare with pro track data then. Nyk/Skavsta  Sweden . 
    anything I can do for you? 
    or should think of. I don’t understand it yet, missed instructions 

    seeing it in commercials on social media nowadays/// blue skies // p.o

    Now we need raw data from digital altimeters (like Atlas, Ares, Viso, Dekunu, Aon, etc.) to support it during import process.

    So, if you have one - just connect it to your laptop and send me the raw data from it.

    Blue skies!

    Nice work !

    Will the app work without network ? I'm currently using an android phone, but can I make it work with an old iPhone not connected to any network ?

    Also, can you give us some details on how the Android version is progressing ? Do you have any Android developpers working on it ?


    Sure, you can use it without a network. Only 3D view depends on it. But you need Iphone 6 and later.

    Honestly, I'm still looking for Android developer. So. Progress is lower than zero :(

    Me again... as I originally thought, the metrics on FF speed is WAY off... I did a belly jump and recorded 330kmh in 22 second free fall.

    App is a good idea and concept but you still have to iron out some of the issues.

    Yeah. You are right. I've found bug in vertical speed calculation. It has solved already in current version.

    Please update.

    I got to use this App last week and I have to say the data is pretty cool to analyze. I am not sure how accurate some of those speeds displayed are, gave me 110kmh horizontal speed on my canopy (lightly loaded at 1.05/1 and a 210) and had my freefall speed (sit flying) at 377kmh lol.

    Vertical speed is pretty accurate. Barometric altimeter sensor is the best sensor in iphone. So 377kmh in sit is ok. I did 420. I compared all my jumps with flysight & protrack.

    Unfortunately, horizontal speed depends on GPS data. GPS is not so accurate. Sometimes it is ok, sometimes it is not. There are some math algorithms inside which makes horizontal movements more precise than raw GPS data (I'm using accelerometers, gyroscopes, magnetometers and heuristic about dive to make raw GPS better). 

    I'm still working on math, and I'm sure it will be better and better.

    1. Will a jumper be able to add notes to the jump (others on the dive, type of dive, record jump, personal notes. etc.) 

    You can do this right now. Comments, types of dive, etc.

    2. When the skydiver breaks the phone - is all the info stored somewhere in the cloud by you? Or does it use the jumpers cloud (OneDrive, GDrive, DropBox, etc.)  Bottom line: If we drop it and the phone is destroyed - how do we get the data back?  

    I've made an update (it is on review now) with personal profile (email+password / facebook).

    I'm going to make export/import for the data a bit later. The next function will be competitions :)

    Hi, i have few questions concerning your app : 
    - If it gives stats on your jump, It means that you should have your phone with you during the jump ?

    - How do you get these stats ?

    - Can all skydivers jump with their phones or only experienced one can like with a camera ?


     - yes, you should have your phone with you. You should press start button on the ground or on the plane and press stop after landing.

    - The core of stats is math algorithm which mixes data from GPS, 3d accelerometers, 3d gyroscopes and 3d magnetometers.

    - Every skydivers can jump with phones, more over it USPA suggestion to do so because it can help you in case of off-landing/injuries/etc.

    Sorry for late reply, I was in area with no cellular coverage :(


  8. Hi guys,

    I'm developer of Skyduck - the new mobile app for skydivers.
    I'm trying to make the best app for skydivers, so I need your help. 
    First of all I need your feedback.

    Now it is in open beta test and available for iOS devices (iPhone 6 and higher except iPhone SE)


    What it is now?

    • Easy-to-use automated skydiving logbook
    • Jumps digital signatures
    • 3D visualization of jump
    • Detailed statistics on a graph
    • Vertical/horizontal speeds

    Blue skies,

  9. Hi!

    Let me introduce myself and vdugnist. We are software developers and we are developing an app for us. It will be a logbook which uses gps, altimeter and motion sensors to record your path like flysight does. Besides regular logbook data this will give you detailed information about your jump (exit/deploy alt, freefall time, horizontal and vertical speed, glide ratio, g-force, etc, etc, ect...).

    Also we want to add logbook signing, export to pdf for printing, local and global competitions and many other features, which is why we need your feedback.

    Please, fill this short survey so we can make the best app. :)

    If you'd like to participate in beta test - just fill three latest field in survey and I'll email you when beta will be ready.

    Thank you in advance!




    I'm going to visit California this February, could you please suggest me a best DZ here? :)
