# SmarTech vs Spotxel® Reader

The clearest difference is review sentiment: Spotxel® Reader at 100% against SmarTech's 25%. Spotxel® Reader also leads on update cadence (every 2 months vs every 12 months). SmarTech's advantage is rating (3.6 vs 2.4) and in-app purchases (none vs 1). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Spotxel® Reader sells 1 one-off in-app purchase. SmarTech asks for nothing beyond the download.

SmarTech holds the better App Store score, 3.6 against 2.4. Both are backed by a comparable volume of ratings — 9 and 7 respectively. Written reviews complicate that: 25% of SmarTech's written reviews are positive against 100% of Spotxel® Reader's, so the app with the better star average is not the one people write more warmly about.

SmarTech ships an update every 12 months, Spotxel® Reader every 2 months. The most recent releases landed on June 1, 2026 and August 12, 2026 respectively.
