Let me start out by saying that I really enjoy Happy Scale. The milestone aspect is really smart and keeps me motivated. As a designer and artist, I appreciate that the design of the UI is clean and looks much more modern than many weight loss apps Ive used.
Ive been using Happy Scale for many months now and I will be purchasing it. Not that I feel I need the other features, but because I feel compelled by the "support an indie developer" part and Im a firm believer if you use an app enough, really enjoy it, and its a reasonable price that you can afford, just buy it! Show your support! Its $5!
My one main criticism though is that I hit my goal weight (Ive since decided to lose more and change my goal weight, thats while Ill continue to use the app) and nothing happened! I kinda expected...something. Some little fanfare of "Hey! You did it! Way to go! 100%!" but...nothing. Hopefully when I lose another 30 pounds and hit my new goal weight, the app will be more pumped for me by then!
I look forward to it!
