Promising app, but accuracy and usability need improvement

I’ve been extensively testing Lifesum, including its AI food recognition, barcode scanning, calorie estimation and nutritional tracking features.

While the app has an attractive interface and some promising features, my overall experience has been disappointing.

My biggest concern is the accuracy and consistency of calorie estimates. Identical meals can produce substantially different results depending on how the information is entered. In one instance, the app initially interpreted 1,620 kilojoules as 1,620 calories, despite the meal containing only 387 calories. Although this could be corrected manually, errors like this undermine confidence in a nutrition-tracking application.

The AI food recognition also needs improvement, particularly when identifying ingredients and estimating portion sizes. I encountered several usability issues, including incorrect time-of-day greetings and confusing serving-size selections.

I’d also like to see more comprehensive nutritional information, particularly micronutrient tracking for vitamins and minerals.

Another frustration was the subscription model. I paid approximately $50 AUD upfront without having a meaningful opportunity to test the premium features first. A seven-day free trial would allow prospective subscribers to make a more informed decision.

There is definitely potential here, but I’d like to see improvements in accuracy, AI reliability, nutritional detail and overall usability.

I hope the developers take this feedback constructively, as addressing these issues would significantly improve the experience.

Can’t customize

I can’t customize a food entry. I can only choose what is offered in the app. That is especially difficult when I make most of my own food.

Needs a lot of work.

This app is great for tracking calories and promoting a healthy lifestyle, and it offers tools for creating established meal plans. But the accuracy needs work when logging certain foods and products, and the barcode feature needs a complete overhaul. Also, some features should be free, like adjusting calories and adding simple additives. Adjusting personal information should not be locked.

Очень нравится данное приложение. Очень удобное

Another app ruined by Ai slop

I’ve used this app for years until I slowly tapered off of it. Now I’m back hoping to start again just to see it’s using some Ai gimmick to reel people in. I’m so over this Ai uproar for absolutely nothing.
