Unless there is some other way of doing it you have to back all the way out to the main menu to watch recorded data, then if you go back in and rescan the vin (even though it wasn’t even removed from the port) and flip though a bunch of other menus to go to other tests. It really slows down and frustrates you going from live data (which is buried to deep in the interface) to the main menu and back again. **Developer response:** We sincerely apologize for the inconvenience. You can find your previously diagnosed vehicles in Diagnostics - Recently - Diagnostics History and access them directly. If you have any other issues, please contact us at support@topdon.com, and our support team will prioritize your case. Your feedback is invaluable to us—thank you for your understanding and support. ### 2/5 — Device bound *2026-06-28* I bought this a while ago. Love it. Except I’ve had a problem with the vci not connecting it says it bound to my email which yes it should be, and yet when I hit activate that’s all it tell me. I am Signed up for the yearly subscription and I can even use it. I’ve messaged your help department nothing. I would just like to use my scan tool. Please any help is appreciated. **Developer response:** We sincerely apologize for the inconvenience and fully understand your frustration. Could you please send us your device serial number (SN) and proof of purchase to us via support@topdon.com. We will prioritize resolving your issue.Your feedback is invaluable to us as we strive to provide better service. ### 2/5 — Updates *2026-06-23, version 6.40.007* Works well when it works, but every time I seem to get this out to read a code there’s updates that make it a much longer process than it needs to be. Makes me miss my wired OBD2 scanner that I could just plug in and it would read the code ### 2/5 — Abo-Falle! *2026-05-03* Das erste Jahr top, danach extrem teuer! **Developer response:** Hallo, wir verstehen Ihre Frustration vollkommen. Topscan kann für ein Jahr ab dem Datum der Aktivierung kostenlos abonniert werden. Wenn Sie den TopScan Lite kaufen, können Sie eine monatliche, vierteljährliche Erneuerung wählen, je nachdem, was für Sie am sinnvollsten ist. Wenn Sie weitere Fragen haben, kontaktieren Sie uns bitte unter support@topdon.com. ### 1/5 — Don’t buy *2026-05-01, version 6.30.008* Requires email and internet to use every time. Complete trash. 0 out of 5 stars ### 1/5 — Vehicles support *2026-04-27, version 6.30.008* They claim to support certain vehicles only to find out the “advanced functionality you need “ is non existent all this is..is a high priced BASIC scanner so be aware. Returning mine today ### 1/5 — Forced a subscription on me after a year *2026-04-25, version 6.30.008* Bought a scanner just for quick little diagnostics and what not after a year I can clear codes unless I pay a subscription rather buy a different brand then forced into a monthly payment. That’s just weird. ### 1/5 — Worst app ever made *2026-03-29, version 6.20.007* If I could give it negative 1000 stars I would. Anyone who was involved with producing it should immediately change careers. Please choose another scan tool, for your mental health ### 1/5 — Requires submission now *2026-03-22, version 6.20.007* You can clear codes without buying the subscription. I had the code reader before any subscription was needed and now I need one just to use it like normal. Why do I need to pay more for something I already bought. This is dumb. ### 1/5 — Thief *2026-03-21, version 6.20.007* Took the 49.99 out of my account but I still have no access to the scan my car. Waste of money on the device and their app. DO NOT BUY! They steal your money that is all! ### 2/5 — Not a free app. Subscription required *2026-03-14* Software works great. Happy with the OBDIi scanner I use. I bought the scanner because the software was free. Now it’s prompting me for payment after three more uses. I only have 1 use left. Not impressed. **Developer response:** Hello, Topscan comes with a complimentary one-year software upgrade. After this period, access to diagnostic software will require a paid subscription. We understand your concern about the cost, but this is also to maintain the progressiveness and compatibility of the software. For expiration, we now have a three-day extension of free usage time. ### 1/5 — Price *2026-03-10, version 6.20.007* Way over priced compared to other brands Choke on it and keep it ### 1/5 — Not working again *2026-02-26, version 6.20.007* The app recently updated an scan won’t work again I tried so many options and still don’t work I need help I would of renewed my yearly plan as well which is $180 ### 1/5 — Does not connect/ Not supported *2026-02-19, version 6.20.007* This is now the second unit that I have bought from TOPDOP and the app doesn’t connect to either of them. I’ve talked to Support. I’ve even tried it on a different phone and these just never work. There is a paywall for any upgrades. These are all things they don’t tell you about. I know someone who is using one on an android device. It seems to work, but not very well. I’ve contacted top down support and they gave me a link on downloading an unapproved app from the App Store so I would steer clear . obviously, they know this app doesn’t work if they’re sending you a link to try and download something else from their website. This is one of those things that you get what you pay for. ## Most critical reviews (10 lowest-rated) ### 1/5 — Faut payer sinon il se bloque *2026-08-22* J’ai acheté avec un an d’abonnement et j’ai plus accès car l’abonnement est expiré alors que launch fonctionne même si l’abonnement est expiré, obligé d’acheter un abonnement je me retrouve avec une interface que je peux plus l’utiliser **Developer response:** Désolé pour ce désagrément. Si vous avez acheté un abonnement mais que vous n’arrivez toujours pas à utiliser votre appareil, merci de nous envoyer le numéro de série (SN) de votre appareil à support@topdon.com.

Dont buy that, save money ### 1/5 — Constant updates make it annoying *2026-07-04, version 6.41.002* Annoying to use because large updates and download everytime I go to use the tool ### 1/5 — No good *2026-06-21, version 6.40.007* Not that good, especially for those expensive updates, this should be a little more expensive and free lifetime updates, then it would be worth it ### 1/5 — Ohne Update geht nichts! *2026-06-21* Wenn du dir App unbedingt brauchst will sie ein Update sonst machst du gar nichts Sehr schlecht Topscan bein danke! **Developer response:** Hallo, wir verstehen Ihre Bedenken hinsichtlich der Kosten; diese Maßnahme dient jedoch dazu, die Weiterentwicklung und Kompatibilität der Software zu gewährleisten. Was den Ablauf der Nutzungsdauer betrifft, bieten wir nun eine dreitägige Verlängerung der kostenlosen Nutzungszeit an. Sie haben weiterhin Zugriff auf die dauerhaft kostenlosen Funktionen, wie auf unserer Website aufgeführt: https://www.topdon.com/products/topscan ### 1/5 — Scandaleux *2026-06-20* Pour accéder à toute les possibilités de l’appareil il est nécessaire de souscrire à un abonnement très onéreux, le tout pour un fonctionnement assez aléatoire **Developer response:** Bonjour, le Topscan inclut une mise à jour logicielle gratuite d'un an. Au-delà de cette période, l'accès au logiciel de diagnostic nécessitera un abonnement payant. Nous comprenons vos préoccupations concernant le coût, mais cette mesure vise également à garantir l'évolution et la compatibilité du logiciel. Concernant l'expiration, nous proposons désormais une prolongation de trois jours de la période d'utilisation gratuite. ### 1/5 — Too many update *2026-06-19* アップデートおおすぎ **Developer response:** ご迷惑をおかけして申し訳ございません。今回のアップデートは、一部の車種におけるソフトウェアの不具合を修正し、よりスムーズで快適なユーザーエクスペリエンスを提供するためのものです。具体的にどのような問題が発生していますか？その他、使用上の問題がございましたら、support@topdon.comまでご連絡ください。弊社のカスタマーサポートチームが最優先で対応させていただきます。お客様からのフィードバックは弊社にとって大変重要です。ご理解とご協力に感謝いたします。 ### 1/5 — FORCED UPDATE APP UNUSABLE *2026-06-16, version 6.40.007* I am driving from ottawa CAN to Los Angeles Cali and the software is forcing on me a 500MB update and there is no way to close the “UPDATE NOW” overlay, so the app is useless gif 2000 mimes until i get to a wifi connection F INH DTUPUD ### 1/5 — Polaris Ranger *2026-05-16, version 6.30.008* Does not support Polaris ### 1/5 — This app is garbage. *2026-05-11, version 6.30.008* The constant logging in to the app with 2FA is completely unnecessary. Who the hell is going to steal my phone and use my ToPDon to fix their car? The app is ridiculous slow to update and you have to stay on the up date screen or it will pause. Can’t go to another app, can’t let the screen sleep. Nope you have to watch it 1% at a time. Just as much fun as watching paint dry. ## Most praised reviews (10 highest-rated) ### 5/5 — Easy Tool *2026-08-22, version 6.41.002* As a shop owner this app/tool has simplified our process and at a realistic cost. The tool nearly trumps my $4000 Matco scanner! ### 5/5 — Great utility *2026-06-27* Works great **Developer response:** Thank you for your good review!

It worked! ### 5/5 — I’m not a Mechanic or nothing just a normal person using it to clear stuff like the engine managemen *2026-06-16, version 6.40.007* This does what I want I’m not a mechanical or nothing but I use it to clear any faults that come up, it is mainly sensors and it clears all perfectly. And it tells me the code and what it is and takes you to the website with the code to do more research. But it is a perfect job for what I want use it for a Nissan ### 5/5 — Good product *2026-05-27* Have had it for three years bought the lite one and then added the 22 bundle only thing it doesn’t have is IMO (or the key thing ). I’ve used it in professional settings and also for friends and family. It works pretty good,I have SnapOn modus but I only use the scope on it because it’s kind of big to take on test drives. I use my phone and iPad , it’s kind of the tool to go to. You need to learn how to navigate it in order to use it correctly, yes sometimes it is a little tedious but not the tools fault just got to learn it. I’ve used it enough to where it helps me on problem cars, but like all scan tools not all can do all you want but this one petty much covers all you may need in a daily bases. Take time to learn your tool , use it as often as you can and you will really be satisfied **Developer response:** Thank you for your good review!

I recommend it for everyone need to do some jobs heavy or light, like own cars to have one scan like this.
