Verdict

The call

The clearest difference is update cadence: Pactra at weekly against Lightweight! Workout Analysis's every 2 months. Pactra also leads on review sentiment (100% vs 76%). Lightweight! Workout Analysis's advantage is ratings volume (181 vs 2) and rating (4.8 vs 4.5). On price, ads, in-app purchases and device support 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 Pactra sells 4 in-app purchases, starting at $4.99 per month. 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 181 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 76% of Lightweight! Workout Analysis's written reviews are positive against 100% of Pactra'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, Pactra weekly. Both last shipped on October 17, 2026.
