Verdict

The call

The clearest difference is update cadence: Kalorim at weekly against Lightweight! Workout Analysis's every 2 months. Kalorim also leads on review sentiment (100% vs 77%). Lightweight! Workout Analysis's advantage is rating (4.8 vs 4.5) and ratings volume (185 vs 22). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lightweight! Workout Analysis sells 3 in-app purchases, starting at $2.99 per month and Kalorim sells 9 in-app purchases, starting at $3.19 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Lightweight! Workout Analysis holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Lightweight! Workout Analysis has 185 ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 77% of Lightweight! Workout Analysis's written reviews are positive against 100% of Kalorim's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lightweight! Workout Analysis ships an update every 2 months, Kalorim weekly. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
