Slay App

Loving the slay app and the exercise programmes, the video demonstrations are fab, better than any PDFS.
I would like to see more of a food log that we could link to our exercise programme, maybe a way of calculating and tracking macros would be beneficial as I’m currently using two apps.
To have everything under one app would be brill and also move my rating to 5 stars!

Okay fitness app

I wish I had seen more of the app before purchasing - it’s a good app if you are looking for pre-planned workouts, however one of the issues I found was when I tried switching out exercises - instead of doing a straight switch for like-for-like body parts, it allows you to choose any exercise across all body parts (bit pointless as it’s broken down by leg, glutes, upper bod etc). The exercises are quite basic even for Level 3 - I was expecting to be wowed and I just wasn’t.

If you’re new to exercising and lifting weights, this is a good app to get started with; however if you are more experienced and looking for diversification, you’ll be disappointed.

Customer service is awful and app doesn’t work

Paid for a yearly subscription to Slay and was really exited to start. However, I cannot login to the app as it keeps telling me the credentials aren’t correct, even though they are. Have reset password a couple of times, followed all of the recommended troubleshooting steps and still cannot access the app.
It is proving impossible to reach the customer services for Slay. The link in the website takes you to a page that doesn’t exist and no response at all from Instagram DM.
I have paid for a service which I am not getting.
