Verdict
The clearest difference is rating: MySign at 2.6 against eTax Mobile's 1.9. MySign also leads on iOS requirement (12.0 vs 15.6). eTax Mobile's advantage is ratings volume (234 vs 5) and update cadence (weekly vs every 3 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
MySign holds the better App Store score, 2.6 against 1.9. That said, the two scores are not equally well evidenced: eTax Mobile has 234 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 6% of eTax Mobile's written reviews are positive against 0% of MySign's, so the app with the better star average is not the one people write more warmly about.
eTax Mobile ships an update weekly, MySign every 3 weeks. The most recent releases landed on September 23, 2026 and September 16, 2026 respectively.
