I have no clue about using the app, mine are old skool stupid controllers. Start at 50% and go from there, I like the rolling wavemaker set at about 10 seconds. Any slower and you get too much rocking of the water and spilling, been there done that. I woke up one morning and the pups wouldn't go into the living room, I sloshed about 5 litres out on the floor. They thought someone had an accident and didn't wanna get blamed for it, lol.
