Hi guys.
Will swim mode (and any others) will be possible be added to our 235? Is it the matter of software or hardware?
I messaged Garmin about this. The new much cheaper vivoactive or whatever its called coming out soon has everything this watch has apart from a few running metrics, and it counts stairs has many modes including swim mode etc. Garmin needs to look after its Forerunner customers. Implementing a swim mode, gym mode etc is no problem it's just a case of using the software they already have and adapting it a bit. There's no justification for not implementing the swim mode or indeed the training parter mode they seem to have removed before release but still advertised! Garmin seem to be deliberately dumbing down devices in software in some attempt to get you to buy something more expensive even though the sensors are already there, or buy multiple devices.
Finally, the SDK is being updated soon in a way that will allow dedicated swimming (or other) apps to be written and downloaded from the Connect IQ store. So Garmin hasn't totally blocked such options, more keeping the headline features separate between their different product lines.
