### 2/5 — Crashes when updating

*2026-06-06, version 1.0.4*

The app crashes when updating 608PD charger.

### 3/5 — Disappointed

*2026-04-30, version 2.2.0*

This app is ruining the brand reputation

### 1/5 — Will Corrupt a N16/N24 charger!

*2024-09-14, version 1.0.4*

This app is signifficatly broken and only detects any N serise charger as an N8 and the subsiqunt firmware update will break your N16 or N24 charger.

### 1/5 — Horrible App!

*2024-08-24, version 2.2.0*

Every time I update the app, everything works for more poorly. I recently updated it and now even batteries with a 98% discharge are showing that they have been fully discharged. You cannot make this stuff up! 

For the record, the hardware is good if you can figure out how to use it without the garbage app poisoning the hardware.

### 1/5 — Unable to bind

*2024-07-15, version 1.2.13*

I have not been able to bind this device to an ISDT FD-200 discharges. 
It times out of bind mode in 4 seconds.

### 1/5 — Bluetooth will not connect

*2024-04-24, version 1.2.13*

What ever you do don’t update the software because you will never connect to the discharger again through Bluetooth. These developers don’t even care to fix the issue. So don’t buy the ISDT FD-200 if your looking for the Bluetooth features.

### 1/5 — Computer Doesn't Recognize

*2024-02-29, version 1.0.4*

I just plugged in my N8 to my Mac OSX 14.2 and the app does not find or recognize that I have plugged in the charger. Charger does power up when connected just fine.

### 1/5 — Cannot update firmware

*2024-02-24, version 1.0.4*

Useless. I have to use Windows app in virtualbox.

### 1/5 — Can’t update firmware

*2024-01-15, version 1.2.13*

App fails to update firmware of ESC. Doesn’t even seem to be downloading. FIX this please!

### 1/5 — Drag brake settings

*2023-12-28, version 1.2.13*

No matter how high I set the drag brake it will not engage in the vehicle ! It just rolls as if no brake at all. Very displeased. I hope there is a fix to this….

### 2/5 — Terribly glitchy with the ESC70

*2023-12-16, version 1.2.13*

Doesn't stay connected via BT, more Error messages than anything, not terribly intuitive, timeout messages etc, just a lousy non functioning app all around.

### 3/5 — Cm 1620

*2023-12-15, version 1.2.13*

Soweit funktioniert die App ganz gut. Nur bei dem wie gesagten CƠM 1620 funktioniert leider die genaue Anzeige von den Zuständen des Akkus und der Stromversorgung leider ohne Funktion. und die Infos über das Ladegerät sind leider zur Hälfte abgeschnitten. ich hoffe auf ein neues Update

### 1/5 — Does not support the Air A8 at all

*2023-12-10, version 1.0.4*

On macOS, the A8 Air is not seen, whether cabled directly via USB-C nor as a Bluetooth device. Firmware cannot be updated because the device cannot be seen or found.

### 3/5 — Ok, but

*2023-11-24, version 1.2.13*

App starts, connects to esc, but connection for firmware update was so unstable, that i thought i bricked the device. It succeeded on the 4th try…

### 3/5 — FD200 discharger problems.

*2023-11-04, version 1.2.13*

1. It is impossible to discharge batteries up to 3.0 volts. They always discharge to 3.3 volts. When you change the tension, nothing changes. There is a very lack of the discharge function to a lower voltage to conduct full-fledged battery tests. There is not enough ability to kill batteries by discharging up to 0.0 volts.  2. It is also not enough to set the discharge current of 6,7,8,9 amperes. 3. Constant conflicts of presets and current changes in current and discharge voltage.

### 1/5 — Old drivers?

*2026-05-30, version 2.2.0*

I guess the drivers are too old for the current iOS. My FD – 200 doesn’t even recognize my iPhone.

### 1/5 — application non fonctionelle

*2026-03-28, version 1.0.4*

l'application envoie un message - Abnormal network connection. Ceci pour indiquer que le serveur back office pour le firmware n'est pas disponnible. Je n'arrive pas à mettre à jour le firmware du chargeur. c'est dommage vu le prix de ces chargeurs.

### 1/5 — Non funziona sul mio Mac con Tahoe

*2026-03-22, version 1.0.4*

Perché non l’aggiornate questa App?

### 1/5 — Não compre nada da ISDT

*2026-02-09, version 2.2.0*

Nenhum app funciona, nem o ISD GO nem o ISD Link.

### 1/5 — Can´t update R8

*2026-01-10, version 1.0.4*

When i hit update it shows „device disconnected“ and the device only beeps

### 1/5 — No device detected

*2025-12-15, version 1.0.4*

No reaction after attaching the computer to an ISDT P160. 
Only „Waiting for device“

### 1/5 — No update possible

*2025-12-08, version 1.0.4*

After clicking update it says device disconnected and N8 stays in the Updating window.

### 1/5 — Does not update

*2025-12-01, version 1.0.4*

It recognizes my C4 Evo charger, but immediately after starting the update it says device disconnected, while the charger remains stuck in 'Updating'.

### 1/5 — Horrible app and glitchy

*2025-02-27, version 2.2.0*

Using it to control a FD-200 discharger. If I swap apps, the Bluetooth doesn’t reconnect so my discharger is now doing whatever it wants to and the app won’t control it.

The current I’ve set is not what it is trying to pull from the battery. The current being pulled from the battery is not what the app is set to or the app is showing. This leads to inaccurate tests.

### 1/5 — No connection, Does not work

*2025-01-09, version 2.2.0*

Can’t connect to my FD-200 Discharger

### 5/5 — Ottimo

*2026-03-19, version 1.0.4*

Ottimi prodotti e App molto pratica. Aggiornamenti firmware sempre disponibili.

### 5/5 — It does what it supposed to

*2026-02-19, version 1.0.4*

This app had one task for me and that’s update the firmware. It did a good job with no error.

### 5/5 — Couldn’t be easier

*2025-03-11, version 1.0.4*

I think this was the easiest firmware update I have ever done. Way to go!

### 5/5 — Macht genau das, was es machen soll.

*2024-12-27, version 2.2.0*

Ich nutze die App seit fast zwei Jahren für Ladegeräte und für den FD-200 Entlader und bisher funktioniert sie problemlos.

### 5/5 — Works fine for me

*2024-08-23, version 1.0.4*

I'm writing this review mostly to counteract the other bad ones, because it worked first time for me. I have an N8 charger, it detected it correctly, and correctly showed updates.

Simple, works fine, and impressive that it's actually in the Mac App Store and not on some random download site.

### 5/5 — iPad 12.9 Successfully Repaired damaged FW for fd-200 !

*2023-01-11, version 2.1.11*

Yes, you read that correct. I tried many devices a year ago to get this stupid device to work. Mine came titled as brand new but someone had opened previously. After this method I am having no disconnecting issues. It was simply an error on the devs programming. I tried my iPhone, SamsungS8 & S2, iPad 11”. Then recently after a year past my OG purchase I tried it on my iPad Pro 3rd gen 12.9 running iOS13.3

### 5/5 — もう少し

*2021-08-15, version 2.0.0*

リフェを放電したいので、カットボルトを1セル2.7から2.8vにかトータルVで5.5〜5.6Vで設定できるようにしてもらいたいです。 3.0vでは、完全に放電できないです。

### 5/5 — Updates ISDT Firmware on Mac

*2021-05-13, version 1.0.3*

Easy firmware update for ISDT battery chargers. I updated my N8 without any problems in under a minute.

### 5/5 — iPadでも利用可能になりました

*2021-02-24, version 1.17*

最高！
iPhoneからiPadへの切り替えも簡単にできるようになりました。

### 5/5 — we need that app in kuwait

*2020-07-08, version 1.12*

:(
