I bought the We-Vibe couples toy - the basic one. It had remote control (no way to see the setting) but not an app.
I'm really sorry to say that we were disappointed and returned it.
It just wasn't for us, and everyone is different.
After 3 pregnancies I couldn't hold it in place by muscle power alone - even wearing knickers it slipped around.
My husband wasn't keen on using it as a couples toy, which kind of defeated the point of it. He is happy to use mini wands and bullets on both of us during foreplay (I know that is still sex and everything rolls into one, but I thnk folk will know what I mean) but once we get down to things he likes it to be just him and me, which is fine.
The vibe just wasn't strong enough for me, solo or together. I'm a power girl and it was just too feeble. Sorry. If you can orgasm through gentle vibes or oral then you may have more luck.
We returned it under the Happiness Promise and chose something different. The concept is great, and if it works for you then that is fantastic!
