Kik messenger 'not installed on this device'

[Festivespooks]

Would this mean he's got it installed on another device?
I know what kik messenger is, it's not great. Unless I'm mistaken and there's an innocent reason to use it?
On playstore for Android you can see what apps have been installed in the past and will say 'not installed' but this kik messenger says its not installed on this device..... He gave his old phone to our son but I know he uses his own Google account and doesn't have kik on his phone.
Any advice please?

It's now saying 'not installed'. Am I going mad?

I downloaded it once, never had an affair or used it at all actually - I was just curious.

In the past an ex had it and used to install and then uninstall it depending on his availability for casual sex

I have a Samsung s9 so i just looked at my library, all the apps no longer on my phone just say 'not installed'. No say 'on this device after', could you have added that on in your mind whilst worrying about it?

I thought it was because the app would be installed on another device (hidden phone /work phone).
I realise it is very easy to say 'leave the relationship' but without getting into it too much its not that easy. Mainly due to my working pattern, if I can't work I can't earn and having to arrange childcare and change my shift pattern would be very difficult.
I appreciate everyone's help though.
Its giving me a lot to think about

Do you have other reasons to suspect him? I have used kik and discord for gaming. There are gaming groups on them for everything even mobile phone games.

Why would anyone leave over 'just' this? I get that the app is used for cheating and I wouldn't be happy with it showing up on my partner's phone but it would need looking into, surely you wouldn't walk out of a long term relationship based on this without doing some serious digging first?

I also just checked my playstore on my phone, I have ITV Hub on my Samsung tablet, but not on my phone, it still says not installed
