# ARMAS vs Visibility Tool

The clearest difference is review sentiment: ARMAS at 100% against Visibility Tool's 50%. ARMAS also leads on price (Free vs $9.99) and update cadence (every 2 months vs every 5 months). Visibility Tool's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 3). On ads, device support and iOS requirement there is nothing between them.

ARMAS is free to download; Visibility Tool costs $9.99 up front. ARMAS sells 3 in-app purchases, starting at $2.99 per year. Visibility Tool asks for nothing beyond the download.

Visibility Tool holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: ARMAS has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of ARMAS's written reviews are positive against 50% of Visibility Tool's, so the app with the better star average is not the one people write more warmly about.

ARMAS ships an update every 2 months, Visibility Tool every 5 months. The most recent releases landed on August 28, 2026 and September 15, 2026 respectively.
