The real question when you look for a FatSecret alternative is not which calorie counter has more foods: it is whether months of diary come with you. With GiFit they do, meal by meal, and before anything is written the app shows you what it is about to import.
In the FatSecret app: Food Diary → Export, and choose PDF or CSV. For the PDF, take the detailed report, the one that lists the foods.
Settings → Data → Import from FatSecret. Pick the file: GiFit reads it on the phone and shows you how many days it is about to import, from when to when, how many foods and the average calories per day.
Nothing is written until you confirm. Then every day is in your diary, in its place, meal by meal.
Every day is checked against the total FatSecret itself wrote: a day that does not add up is not imported, and the summary says so. A day that already has food in GiFit is left as it is, so no lunch is counted twice. Importing the same file again adds nothing, and future days stay out.
That is fine: if you saved it as .xlsx, GiFit reads that too.
The imported diary counts: days from the last 4 weeks go toward the 14 days of diary that GiFit Pro's adaptive maintenance needs — an adaptive TDEE that learns from your diary and your scale how much you really burn. The import brings the diary, not the weigh-ins, and those are needed too: at least 2 weigh-ins a week, in each of the last 2 weeks. Best to weigh yourself every day, at the same time. How adaptive maintenance works.
