Extreme value

After using this app for regular track sessions I am very pleased with the data interface and ability to review and critique your driving afterwards. The fact that this is still in Beta and will have much improvements later on is exciting. The one thing i really would like to see is the ability to track engine oil pressure from the OBD2 data. This is one of the most important items to watch while in high G turns. I recommend anyone tracking their cars to give this app a try with the OBD2 sensor.

External Camera Functionality Required

App interface is really nice and easy to use, it would be 10/10 if we could pair it to a GoPro. Having a phone on a mount is quite intrusive, if the GoPro could have the Dragy overlay on top of it that would be awesome.

Good but buggy + lacking things

My biggest complain is that live lap delta is to your previous lap, not your fastest lap. I don’t care about my current lap is going to my previous throwaway lap, i want to compare to my PB or fastest of the session.

And i’d say about 1 in 5 laps, the delta just stops working and infinitely climbs in time until the end of the lap. It ends up clocking the correct lap time in the end, but i paid a lot of money to get a reliable live delta here

Bugs make it borderline unusable

This app is good and could be great. Overall clean UI and good UX. But the bugs make it REALLY hard to trust. Ive had this app force crash on me twice now while I was on hot laps. The session data also doesnt save when logging into a new device. And after last update, there are now ~25 random tracks (half in asia, but Im located in the US) that were added to "My Tracks" page. This makes finding the actual tracks I use a nightmare. I want this app to be good but these are significantly big bugs that make this app not usable. I wouldnt be able to recommend this until those issues are fixed.

Awesome App

So much better than Garmin Catalyst. Much easier to set up.

Dragy-lap 1.110 no longer works on iPad

This release 1.110 seem to have nice features but is very buggy on an iPhone and useless on iPad.
On iPad in the new 3d mode the canvas of the app is too big so you cannot see all the function of the app on the iPad display. It’s impossible to use it. Can you reverse the release until you fix it?
I
On iPhone the app crash often or function don’t work.
In 3D VS function does allow to choose same track from two separate sessions, but will not display both. ( it will show lap comparison from the same session). App crash occasionally when zooming into the 3D map.

Overlay video time on 3D display drift out of sync with the geo track location.

Not perfect but good for the $

This app is not very intuitive to use, but once you get the hang of it, it’s not bad. The ability to easily create your own “tracks” is very helpful for autocross days. For the price of the draft unit, I’m overall pretty happy with the functionality. With some work on making the app easier to navigate in the heat of the moment, this could be 5 stars.

Thank you for your feedback! We have forwarded your valued suggestion to our development department for their reference. Please feel free to contact support@godragy.com if you have any questions. We appreciate your support!

Good, with a bug fix request

App connects easily and recorded my lap times pretty perfectly. Great feature to record from both cameras simultaneously - getting both front and cabin video.

Request: exporting video the PIP video is exported upside down. Fix and it’s a 5-star app!

Need CarPlay

Overall the app is easy to use and Dragy feels comparable to Catalyst for a fraction of price. It would be perfect if the app can have CarPlay support.

Few questions

Thanks for the great UI, it really looks very nice. And the usage of your app is also going well in general.
However I have several questions:
1) Is it possible to export the telemetry file to either share it with someone or use in another app?
2) is it possible to connect OBD to Dragy lap to get more info?
3) Not sure why, but I’m experiencing issues with adding video from DJI camera (get an error “there is no data from GoPro GPS sensors”). However I even don’t need that data, I just would like to get the video with overlay from Dragy…

Response from developer

Thank you for your detailed feedback and kind words about the app UI—we really appreciate it! To answer your questions: 1. **Telemetry Export**: Yes, you can export your session as a `.vbo` file for in-depth analysis with third-party tools. You can also export as a `.dlap` file for sharing between devices or with our support team. 2. **OBD Integration**: OBD support is not available yet, but we’re excited to share that **Dragy OBD** will be launched later this year! It will allow users to access additional data such as throttle, RPM, and more. 3. **DJI Video Import Issue**: Dragy Lap currently supports **DJI Osmo Action 4** for automatic overlay, but it requires the **DJI GPS Bluetooth Remote Controller** to sync GPS data with the video. We understand your need to overlay Dragy data on DJI videos without relying on camera GPS, and we’re actively working to reduce these limitations and expand support to more action cameras soon. Please don’t hesitate to reach out to [support@godragy.com](mailto:support@godragy.com) if you’d like help exporting files or troubleshooting video sync. Thanks again for your support!

Not registering lap times

Ran great at my first track day with the Dragy Lap at Laguna Seca. At Laguna I only used it as a track timer…Second track day was at Chuckwalla where I used my phone to record… 2 problems during this day were not registering the track times(always red 00:00 on my 3rd -5th sessions despite turning phone off and back on, logging out of the app and back in etc etc. Also the video overlays with mph and other data are several seconds out of sync with the video. Don’t think I can trust this to do what it is supposed to do. There is no technical help inside the app.

Can you please fix the following bug

It’s been two years since I first reported this bug, and I’ve followed up multiple times.

When using the app on long lap tracks with video recording—where each lap takes over 10 minutes—if you stop the recording and hit Exit after the second lap (or later), resulting in more than 20 minutes of recorded video, the app crashes. The recorded video is lost, but the telemetry data remains intact.

Please fix

Thank you

PARA CUANDO MEJORAD EN LA APP

Es una App muy útil pero falla mucho, no permite modificar ni borrar eventos aún.
Va por buen camino pero hace falta una buena actualización

Slow ah app

So much potential but the app it’s self is awful, fails to connect to the the server, I just want to download my footage why is it so buggy. Same with the other dragy app. Dogged. Plz fix as it’s actually a really useful tool but really inconsistent with the apps itself which lets it down

Great app sometimes freezes

I get a lot of data from the app, it is fantastic to take out on track. Sometimes the app freezes whilst out on track. I have to quit the app and relaunch and your data is lost.

App is great but..

Would be a 5 star if they fixed the bug that many historical accounts that have had dragy for a while are not able to add a vehicle to the lap timer. Error of “session no exist” pops up. It actually adds the vehicle to the dragy straight line app but not the lap timer. Therefore not allowing you to use leaderboard and many app features. This has been a pain point for a while and many people I track with have same issue. Dragy please let people know how to overcome this “session no exist” issue and you could quickly become the lap timer of choice. In theory this is a great cost effective solution but it has to work proper. You are on to something but please get the simple bugs out.

Won’t allow me to add a car.

I love this app, but it has it’s flaws. I’ve emailed support now twice due to the app not allowing me to add a vehicle to my account. It keeps saying “session no exist” without being able to add my car(2007 Chevrolet corvette)I cannot share or export my track times & video. PLEASE FIX THE ERROR.

Session no exist

Whenever I am trying to share the session or add my car in the list I receive this message. It is also not possible to export the data to vbo format since I am not able to share any results. Could you please fix the issue?

Response from developer

Thank you for your feedback and sorry for the inconvenience. Please kindly ensure to update the app to the latest version, try to log out and log in back to see if the problem persists. For your information, please do not uninstall/reinstall the app to avoid data loss. If the problem persists, please contact support@godragy.com for further assistance. We appreciate your support!

Easily go from runs to racetrack!

This is the perfect way to avoid buying a dedicated lap timer. Times are accurate to transponder times by the race track to the +- .005. The app has a lot of potential and I hope you guys continue development of this. More promotion could also be done. Many people don’t know and the buy garmin catalysts. Dev team. Just do the same thing as the catalyst. It would be nice to have a coach added function to this app. But it takes lap times well. Add a track beta is glitchy and I had to keep making a new track to have a go button to hit. The tracks in “my tracks” have no “go “ button. But I was able to just create a track every time to get times at chuckwalla ccw
