Meet Blinky: your emotional support fluff
Most weight loss apps give you charts and streaks. Simple gives you Blinky.

I got the 1 month subscription Jan 4th. I really like the features & no counting calories. The fasting isn't as hard as I thought it would be. I've been walking 30 mins or more almost everyday. So far I'm down 16lbs in 6 weeks!! I only have 7lbs to go, & at this rate, I will probably aim for another 5-10lbs. Super happy with the progress! The app keeps me on track with weight, food, water & movement Plz know that it automatically renews itself, until you cancel.

The app helps with accountability, can definitely give you motivation & support. I've struggled with weight for a long time even though it doesn't show due to my height. Now I know when I'm dropping weight and why I'm dropping weight, which helps with my anxiety towards sickness. I give this app a 4 with some time it could get better. My only issue was the sign up. A lot more expensive even though everything was saying discount. It moved to the original Price. Not fun!

USES FASTING AS IT'S PRIMARY WEIGHT LOSS TECHNIQUE I got this app after seeing a few ads and paid the $15 for 1 month (which has to be canceled thru email). What they don't tell you in the ads, description, or reviews is that it wants you to fast! I hate that. I felt lied to. The nutrition score wasn't that accurate. However, the food suggestions were nice (but you have to use the AI chatbot to get them). I did not use the app for exercise but it looked good and well-tailored.
