Verdict

The call

The clearest difference is monetization model: ExRx.net Workout Tools at freemium against Days's subscription. ExRx.net Workout Tools also leads on update cadence (every 2 weeks vs every 2 months). Days's advantage is ratings volume (922 vs 7) and rating (4.3 vs 4.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Days sells 1 in-app purchase, starting at $59.99 per year and ExRx.net Workout Tools sells 2 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

Days holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Days has 922 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 59% of Days's written reviews are positive against 67% of ExRx.net Workout Tools's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Days ships an update every 2 months, ExRx.net Workout Tools every 2 weeks. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
