Start a switch from FatSecret by saving important records and briefly testing the new app. For daily logging, your current goals, usual foods and recipes will matter most. Automatic history transfer from FatSecret to kkal.ai is not confirmed: this guide covers manual setup without promising a one-tap import of your entire diary.
1. Save the information you use
Before switching, note your current calorie and macro goals, measurement units and usual portions. Save frequently used recipes, ingredient weights and the weight of the finished dish. If past entries and weight trends matter to you, keep an available copy or dated screenshots. Do not delete your old account until you have checked that you still have the records you need.
What to move first
| Information | What to do when switching |
|---|---|
| Goals and measurement units | Write down the values and check them in the new app's settings |
| Frequent foods and portions | Find them again and compare entries with labels |
| Home recipes | Save ingredients, their weights and the finished dish's weight |
| Food and weight history | Keep a separate copy; do not rely on automatic import |
2. Set up kkal.ai and check your goals
After installation, choose your preferred language and check weight and height units. Compare the new app's goals with the ones you used previously: the initial estimate may differ because of activity settings and other inputs. Recheck those settings before changing both your app and your entire eating approach at once. If a professional set your target, follow their guidance.
3. Check foods using one simple example
Start with familiar yogurt or another packaged food with a label. Find it manually or by barcode, check calories and macros per 100 g, then enter your portion weight. For example, values for 150 g should be 1.5 times the values for 100 g. If two diaries disagree, first check the food entry and portion: identical names do not guarantee identical database records.
4. Recreate a few home-cooked meals
Start with three to five dishes you cook most often. For manual entries, use your saved ingredients and the same measurement method: do not compare dry grain weight with cooked porridge weight. Use the finished dish's weight when calculating a portion. You do not have to move your entire archive in one evening; set up what you need for your next meals first.
5. Test photo logging
Photograph a familiar lunch and check which foods kkal.ai detected. Correct ingredients and portions and add anything missed that was in the meal. Oil, sauces and fillings may not be visible in the photo. Judge how easy it is to review the result: a photo helps start an entry, but it does not measure exact weight or replace a label or recipe.
6. Compare a few ordinary days
Keep access to both diaries briefly. Compare the steps needed for breakfast, a snack and a home-cooked dinner, how easy editing is, and how you view daily totals. Do not expect identical numbers: databases and portion assumptions vary. For a large discrepancy, check specific foods, units and added ingredients before choosing one app.
7. Check your subscription separately
Installing a new app does not cancel an existing subscription. If you have FatSecret Premium, check the payment method, renewal date and subscription controls in the service where you purchased it. kkal.ai also offers optional purchases; open the feature you need and read its terms before paying. Saving history, deleting an account and cancelling a subscription are separate actions.
Start with one familiar day
Install kkal.ai, check your goals and add a familiar breakfast. Once you understand portions and editing, move on to your other meals. Use the alternatives guide to choose an app, and the FatSecret or kkal.ai article to compare those two diaries directly.
