I've just started using LifeSum again after a break of over a year. I used to have the Premium version, but have just started back with the standard version. Luckily it has saved all of my previously-inserted meals and recipes.
I used to be able to insert a decimal point in the number of servings box to get a completely accurate calorie count.
For example, I make my own bread and I know how many calories per gram there is, so I used to be able to input e.g. 2.4 or 1.7 servings to get an accurate count, depending on how thickly I slice the bread!
Also, sometimes the calories that LifeSum shows can be a little bit off, even using the barcode reader, so I'd work out using whatever it says on the packaging re: calories per 100g and adjust the portion size accordingly.
Now it seems that I can only insert whole numbers in the number of portions box. Which is annoying, as sometimes there is a huge difference between 1 and 2 portions of something, when you've eaten 1.5 portions.
I was wondering whether this is because I am using the free version of the app (Android version) or if LifeSum has removed the option of putting in decimal points for some reason.
