Verdict
The clearest difference is rating: NumberBox at 4.5 against EMSFIT Pro's 1.3. NumberBox also leads on ratings volume (565 vs 3) and update cadence (every 2 months vs every 6 months). EMSFIT Pro's advantage is iOS requirement (12.2 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

NumberBox holds the better App Store score, 4.5 against 1.3. That said, the two scores are not equally well evidenced: NumberBox has 565 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 50% of EMSFIT Pro's written reviews are positive against 64% of NumberBox's.
EMSFIT Pro ships an update every 6 months, NumberBox every 2 months. Both last shipped on November 5, 2026.
