# HINT Control vs Voltage

The clearest difference is in-app purchases: HINT Control at none against Voltage's 5. HINT Control also leads on review sentiment (66% vs 33%) and ratings volume (114 vs 14). Voltage's advantage is rating (4.5 vs 4.3) and update cadence (every 5 days vs every 2 weeks). On price and ads there is nothing between them.

Both are free to download. Voltage sells 5 one-off in-app purchases. HINT Control asks for nothing beyond the download.

Voltage holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: HINT Control has 114 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 66% of HINT Control's written reviews are positive against 33% of Voltage's, so the app with the better star average is not the one people write more warmly about.

HINT Control ships an update every 2 weeks, Voltage every 5 days. The most recent releases landed on November 3, 2026 and November 10, 2026 respectively.
