The ease of use for new customers! I used it with my wife who had been taking her health seriously since she was young but hadn't managed to lose weight or keep up exercise until speedoC entered our lives - now we both feel more energetic all day long! There isn’t much that can be said negative about this app; maybe add an option when you upload photos instead just having 'upload image' as one big menu item? It also looks like they want people only uploading their own pictures (for profile photo etc). If anyone is looking at losing some stubborn last bit of fat then go ahead using speedOC!! We've lost 14kg combined over 8 weeks!! Some basic workouts during each week helps us achieve better results than expected without even thinking too hard-it really does make exercises fun again after quite sometime away from them. You'll see how many calories your burning per minutes which makes calorie control less complicated if needed.-the food tracking tool allows me time what meals i choose next and why so effectively. I have used this product for my skin problems like Acne Scars etc and it works well with me! It is very gentle that's why i can use without any side effect (if you are using other products) but if your acne scars problem then try speedo cream as its really good stuff!! No one should be unhappy after buying speedo because they will get satisfied of their own health issues solved by them so easily.
