This is the best option for those who don’t want to break the bank and still get your track times. ### 5/5 — Extreme value *2026-06-08* 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. ### 3/5 — External Camera Functionality Required *2026-05-10, version 1.131* 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. ### 3/5 — Good but buggy + lacking things *2026-04-29* 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 ### 2/5 — Bugs make it borderline unusable *2026-03-09* 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. ### 5/5 — Awesome App *2025-11-10, version 1.110.2* So much better than Garmin Catalyst. Much easier to set up. ### 2/5 — Dragy-lap 1.110 no longer works on iPad *2025-11-05* 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. **Developer response:** Thank you for your detailed feedback, and we’re truly sorry for the inconvenience caused by version 1.110. Our team has already identified the issues you mentioned on both iPhone and iPad and is actively working to resolve them. We’ll release a fix very soon to restore full functionality and improve overall stability. Thank you again for your patience and for helping us make Dragy Lap better with your feedback! ### 4/5 — Not perfect but good for the $ *2025-11-03* 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. ### 1/5 — Dragy-lap 1.110 no longer on iPad *2025-10-29* This release 1.110 seem to have nice features but is very buggy on an iPhone and useless on iPad. On iPad 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. . An 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 tow 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. **Developer response:** 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.
