# VIIO vs TEO+

The clearest difference is in-app purchases: TEO+ at none against VIIO's 10. TEO+ also leads on rating (5.0 vs 4.7) and iOS requirement (12.2 vs 15.6). VIIO's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (1.2K vs 1). On price, ads and device support there is nothing between them.

Both are free to download. VIIO sells 10 in-app purchases, starting at $2.99 per month. TEO+ asks for nothing beyond the download.

TEO+ holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: VIIO has 1.2K ratings behind it against 1, so its average is the more settled of the two.

VIIO ships an update fortnightly, TEO+ every 4 months. The most recent releases landed on September 29, 2026 and June 23, 2026 respectively.
