### 1/5 — What happened to tekin

*2025-09-06, version 20.46.0*

My phone app says my tekin esc is to new of a version for the app, and the pc says my pc is to new to run the tekin download on there. Tekin use to be top not, but seems to be a huge waste of money now. Guess i have 2 rx8 esc’s that are paperweights now

### 5/5 — Hotwire App

*2023-10-16, version 20.46.0*

App works as it should - great for making adjustments while trackside.  Easy interface to fine tune the control of your Tekin products. 

NOTE: If you have any issues connecting to a new esc be sure to calibrate first.

### 2/5 — Hot wire

*2023-01-29, version 20.46.0*

It’s ok it works but u would think they would fix that u can’t read the settings because they are to high on the screen and are cut off, other than that I would of given 5 star it just frustrating

### 4/5 — Almost perfect!

*2022-05-07, version 20.46.0*

The UI could use just a little help. Sometimes the number your setting on a setting is hidden by a bar up top. If all the sliders/UI where bumped down to center the screen instead of being on top it would fix it. Also string a + - button for fine tuning would set it off. Other than that add the dataloding to the app and this is best in class.

### 1/5 — Very buggy

*2022-05-05, version 20.46.0*

The app does not accurately read my ESC settings and does not accurately apply new settings. NOT reliable on race day and I always revert to hooking up to a laptop for accurate and reliable use. App does not render correctly on my iPhone 11 and it chops off critical setting information from view. Needs an update badly. Revamp the app and I’ll be happy to change my rating. Till then, I recommend to all my team mates to stay away from the Bluetooth on iPhone and use a laptop for serious tuning.

### 5/5 — Gary Glover

*2021-06-16, version 20.43.0*

Would like to see data logs

### 5/5 — Where is 280?

*2021-06-07, version 19.32.0*

No 280 or drag for apple?

### 1/5 — V280 firmware incompatible

*2021-05-24, version 19.32.0*

Does NOT work with v280 eliminator firmware in esc... no responses from tekin and removing posts on Facebook asking questions.... still no update for saving profiles or others with new firmware for over 3 months!!!!!!

### 1/5 — The app doesn’t work properly

*2021-05-17, version 19.32.0*

I’m very disappointed with the Tekin folks, their products is top notch and very expensive but this app needs a lot work, for starters the app has not been updated in over a year, when you open the app stuff looks out of place like the image I’m looking at is too big for my phone’s screen and the app is not compatible with their newest esc software (280) so if you’ve updated your esc to their latest esc software be ready to only be able to make changes to your esc on a pc. I hope an update is coming out soon for us app users.

### 1/5 — App needs update

*2021-04-04, version 19.32.0*

Does not recognize eliminator update v280 on app
