I'm looking to replace the Bontrager computer on my secondary bike (don't remember its model off hand.) It does have an ANT+ speed/cadence sensor. My Primary bike has a Bontrager Node 1.1 w/ dual band Ant+/Bluetooth. I'm split between getting a new computer for the secondary bike (leaving my primary alone) and move the Node to the secondary bike and getting a different computer or phone app for the primary bike. Main features I'm wanting regardless are speed & cadence. GPS would be nice in case I'm in a new area. I typically ride the same routes and usually don't do group rides or post where I've been for others to see.

So I guess what would either be a decent Ant+ computer (speed/cadence) for my secondary bike
Or a decent computer/smart phone app (speed, cadence, alt?) for my primary bike? Sensor on that bike is both blue tooth & Ant+
