Shark Apnea Trainer - Freediving breathing exercises and tables

@gubikmic normal, I think, that training is even more about how to hold breathing. I've added instruction to "Guide and safety" in the settings, and I would be happy if you able to check it and give me advice on how to improve it

@huangsemao ah yes, that's helpful. I would recommend to emphasize the warning under basic safety: "Never train alone in water, even in a pool. People have died doing this. You can lose consciousness gradually without realizing it and a minute later it's too late."

@gubikmic good idea, and probably need to move the "basic safety" section before the "training process guide"

@michael_makdah thanks. I made that app for my freediving training in the begging, and then I began to improve it based on other freediver's feedback. There would be more features in the future

@anastasiya_v_ I'm happy that you love it 🦈
