However, no matter how many times I set my carbs to “3” my log screen says I have “2” left. Additionally, when I enter my weight, it still gives recommended water levels for someone 120 lbs. I recommend the developer fix these bugs and it would be a 5 star app. **Developer response:** Hi Akon, I am very sorry I missed this review. I was not notified of it. I just released an update that fixes the setup wizards (the actual issue). If you have any questions or suggestions please contact me. Email in the app. Thank you, Tony. ## Frequently asked questions about 21 Day Slimple ### How do I move to Day 2 in 21 Day Slimple? 21 Day Slimple is a self-paced app. You control when you move to the next day or workout, allowing you to progress at your own speed through the 21-day cycle. ### What are the different 21-day schedules available in 21 Day Slimple? 21 Day Slimple offers a base 21-day schedule and an extreme 21-day schedule.
