# Grindcalculator vs 1GlanceApp

The clearest difference is price: 1GlanceApp at Free against Grindcalculator's $6.99. 1GlanceApp also leads on rating (4.4 vs 1.0) and ratings volume (10 vs 1). Grindcalculator's advantage is in-app purchases (none vs 3) and review sentiment (85% vs 60%). On ads and device support there is nothing between them.

1GlanceApp is free to download; Grindcalculator costs $6.99 up front. 1GlanceApp sells 3 in-app purchases, starting at $2.99 per month. Grindcalculator asks for nothing beyond the download.

1GlanceApp holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: 1GlanceApp has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 85% of Grindcalculator's written reviews are positive against 60% of 1GlanceApp's, so the app with the better star average is not the one people write more warmly about.

Grindcalculator ships an update every 4 days, 1GlanceApp every 2 weeks. Both last shipped on November 3, 2026.
