# SMART vs JR Smart

The clearest difference is in-app purchases: JR Smart at none against SMART's 12. JR Smart also leads on ads (none vs shown) and review sentiment (50% vs 19%). SMART's advantage is update cadence (monthly vs every 18 months) and ratings volume (1.4K vs 9). On price and device support there is nothing between them.

Both are free to download. SMART sells 12 one-off in-app purchases. JR Smart asks for nothing beyond the download.

SMART holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: SMART has 1.4K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 19% of SMART's written reviews are positive against 50% of JR Smart's, so the app with the better star average is not the one people write more warmly about.

SMART ships an update monthly, JR Smart every 18 months. The most recent releases landed on September 28, 2026 and August 6, 2026 respectively.
