Verdict
The clearest difference is rating: SMSVia at 4.0 against DoomMath's 1.0. SMSVia also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 3 days vs every 2 weeks). DoomMath's advantage is ads (none vs shown). On price 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. DoomMath sells 2 in-app purchases, starting at $34.99 per year and SMSVia sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
SMSVia holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: SMSVia has 8 ratings behind it against 1, so its average is the more settled of the two.
DoomMath ships an update every 2 weeks, SMSVia every 3 days. The most recent releases landed on November 5, 2026 and November 9, 2026 respectively.
