I use MFP for many years now, you have to be careful when adding a food for the first time because apparently no one checks if the entries are valid or not and many foods are way off on macros. If you eat the same 10-20 foods everyday it's easy to use and accurate. Also i don't understand how can you not make adjustments to the previous day, i can do it no problem..for any day that has passed, it was never a problem. If you go and open the app after midnight it starts from the new day but you can always go to previous day and change whatever you want. Also you can create your own recipes, you add all the ingredients, you chose how many meals that is and you have perfect track for every meal. It's convenient and i really like it, although lately it's a pain in the ass though with the ads and the hurry to subscribe.
