I have a fabulous recommendation for you all!
It's a new App called Vocal Warmup by Vocal Process.
The folks behind it are both expert vocal coaches, Gillyanne Keyes and Jeremy Fisher whom I have done a number of training courses with. It is a fab bit of kit and has just been certified by the NHS as being safe to use to rehabilitate the voice after COVID.
The exercises cover Singing and Speaking as well as handy stretches for the body to aid with efficient breath use and vocal production.
Happy App playing everyone!
