Bulk, cut or maintain?
If your main goal is building muscle, eat slightly above maintenance (lean bulk). To lose fat without losing strength, eat about 20% below maintenance and keep protein high. Somewhere in between? Maintenance with heavy training is a great choice.
Keep lifting heavy, even in a cut
In a cut, the signal to keep your muscle matters more than ever. Keep lifting the same weights. In the Stren app you see what you did last time on every set, so you notice right away whether you are keeping your strength.
