20lb target - achieved in 3 months


Fantastic app. I've been recommending it to everyone. I've lost 20lbs very easily and have no fear of putting it back on as this app is my slimming buddy. It's also encouraged me to take up regular exercise. I now can see the direct consequence of eating fatty food - I now choose some fruit or oat cakes instead. Brilliant.
-30lbs in 5 months-
Still going strong have lost an additional 10lbs so wearing clothes 3 sizes smaller. Feeling energetic and looking 10 years younger (not my comment!!)
I'm hoping this will still work for me in maintenance mode
Still using in maintenance mode 18 months on. Great for keeping focus when a few pounds sneak back.
When I get lazy about filling in the data the pounds creep back. So this app really is like a diet buddy. Keeping on top of the weight is just a matter of staying true to my buddy. I agree with some of the posters about updates not necessarily being improvements. But the alternative of not using this app is not something I could contemplate now.

Still happy with my slimming buddy nearly 4 years on. Keeping my focus on my goal weight after the summer vacation helps to keep me on track.

Still using this great little app. Helping hand when things go off track. Brilliant. Highly recommended
Still using to keep me focused when I’m trying to get back to my new normal. After holidays or Christmas festivities.

New format is a step down in my opinion


I’ve used my net diary since 2012. Over the 6 years I’ve tracked the majority of the time, especially during contest prep.
The app is easy to use/ navigate, I initially picked mynet and have chosen to stick with it over other apps due to its ability to fully customise, including calorie/ macro set up. Since the recent format upgrade (2018), this is starting to slip away.
Now the apps recommended/ generic settings based on your weight/ goals will kick in if it doesn’t agree with something. It won’t allow average weekly exercise to be entered with the resulting calorie deficits regardless of end goal, without automatically adjusting target or required calories/ macros.
Disappointing really as I have enjoyed using the app over the years...

Love the new version!!


I put a little bit of weight on recently, so when I got back from holiday 6 weeks ago I returned to the app to help me shift 7lbs. Wow! It has seriously been improved since I last used it! Have already lost the weight I needed to, but will keep using the app to monitor my food intake and make sure it stays off. Love the new calendar option to select any past day to copy a meal. Suggestions: after copying a past meal, flick back to today automatically as it’s easy to get in a muddle. Also, maybe convert the steps recorded by the app or phone into calories burned to save remembering to turn on the exercise option. Great app!
