### 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!

### 1/5 — Don’t buy

*2026-08-19, version 6.41.002*

Don’t provide even basic functionality without yearly subscription. 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

### 3/5 — So close

*2026-07-03, version 6.41.002*

As a DIYer I wish I could save my vehicle’s profile so you don’t have to scan the vin everytime. 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.

### 2/5 — Device bound

*2026-06-28, version 6.40.007*

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.

### 5/5 — Great utility

*2026-06-27, version 6.40.007*

Works great

### 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

### 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.
