# EMS Pro vs OneDose

The clearest difference is update cadence: OneDose at every 10 days against EMS Pro's every 3 months. OneDose also leads on ratings volume (36 vs 5). EMS Pro's advantage is rating (4.6 vs 4.3) and iOS requirement (13.0 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

EMS Pro holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: OneDose has 36 ratings behind it against 5, so its average is the more settled of the two. Written reviews split almost evenly too, at 80% and 80% positive.

EMS Pro ships an update every 3 months, OneDose every 10 days. The most recent releases landed on June 7, 2026 and September 19, 2026 respectively.
