What’s the difference between the two applications ? Any advantage of using one over the other?
Similarities pointed out so far:
Both are accessible via Bluetooth Modules
Both have Telemetry viewing capabilities.
Differences:
Ackmaniac is Android only
Metr/Perimetr is iOS and Android
Edit: Also turning this into a Wiki for public contribution. Better to have everything on the top post than scattered throughout the thread.
METR plugs into your vesc and gives you telemetry on the go (on your phone)
@Ackmaniac is just vesc firmware and tools (modified) and lets you do a whole lot of cool things. No telemetry on your phone out of the box. Check out his thread for more info.
Darn… I figured i missed something… xD

Fixed that for you dude. 
+1 kudos for you dude. Thanks 
For anyone who’s reading this… Ignore my initial comment xD
with metr you need to buy their bluetooth module, i think there’s a mac address lock on it.
ackmaniac’s you can source your own hm10 bluetooth module.
maybe metr has some better visual like the graph built into the app, but ackmaniac’s outputs raw data to csv which you can then export to a visualizer after your ride.
Mets is a fancy looking one but its paid, ackmaniack has also an app it does the job amazing but is not as nice looking as metr but it does the job great and its free so who cares
I see , thank you for all the replies. I’ll be editing the title/question since My true question is Ackmaniac vs Metr/Perimetr
Edit: also made the thread a wiki , edit away at your leisure.
Also Ackmaniac app it’s only for Android
Which is the best thing in the world. Open source is nothing to be ashamed of.
Where’s the wiki?
Edit: ooh, did not know this functionality existed!
Wtf no one uses the video overlay?
