What is Bay?
Bay is an AI fitness coach you text. Send a photo of your lunch and Bay counts the calories. Tell it your goal and it writes your workout plan. It checks in every day so you keep going. It all happens in the Messages app already on your phone, iPhone or Android, with nothing to download.
How do I log a meal with Bay?
Just tell Bay what you ate. Text “2 eggs and toast”, send a photo of your plate, or send a voice note. Bay works out the calories and protein and adds them to your day. Fix a portion once and Bay remembers it next time.
Does Bay make personalized workout plans?
Yes. Tell Bay your goal and how many days a week you can train, and it writes a plan just for you. Text your sets after each workout and Bay keeps track, then tells you when it is time to add weight. Mention a sore knee or shoulder and it swaps the exercises.
Do I need to download an app?
No. Bay works inside the Messages app already on your phone. Save the number, text “hi”, answer a few quick questions, and you are set.
Does Bay work on Android?
Yes. Bay works on iPhone and Android. If your phone can send a text, Bay works on it.
How much does Bay cost?
Bay is free right now. If that ever changes, members will hear about it first.
What are daily check-ins?
Every morning Bay texts you the plan for the day: your calorie and protein targets, plus the workout if you have one. Every evening it sends a quick recap. If you have not logged anything by early afternoon, it sends one friendly reminder, never more. Want quiet? Text “skip the nudges this weekend”.
Is Bay medical advice?
No. Bay is software, not a doctor, dietitian or certified trainer, so nothing it says is medical, nutrition or professional advice. Check with a professional before changing how you eat or train, especially if you have a health condition. You need to be 18 or older to use Bay.
How do I stop the texts?
Text STOP and Bay stops texting you. Text START to come back. To delete your data, text “delete my data” and Bay will tell you how.
