# SIMO vs Voice

The clearest difference is rating: SIMO at 4.8 against Voice's 1.0. SIMO also leads on ads (none vs shown) and ratings volume (3.3K vs 1). Voice's advantage is in-app purchases (none vs 2) and update cadence (fortnightly vs every 2 months). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. SIMO sells 2 one-off in-app purchases. Voice asks for nothing beyond the download.

SIMO holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: SIMO has 3.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 58% of SIMO's written reviews are positive against 50% of Voice's.

SIMO ships an update every 2 months, Voice fortnightly. The most recent releases landed on September 27, 2026 and September 17, 2026 respectively.
