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.
sfty holds the better App Store score, 4.0 against 1.8. That said, the two scores are not equally well evidenced: Smart has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of sfty's written reviews are positive against 17% of Smart's, so the app with the better star average is not the one people write more warmly about.
sfty ships an update every 4 months, Smart every 2 months. The most recent releases landed on October 16, 2026 and October 24, 2026 respectively.
