# Frequency vs Tuning Fork Studio

The clearest difference is in-app purchases: Frequency at none against Tuning Fork Studio's 3. Frequency also leads on ratings volume (340 vs 1) and update cadence (fortnightly vs every 3 months). Tuning Fork Studio's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On price, monetization model, device support and iOS requirement there is nothing between them.

Both are free to download. Tuning Fork Studio sells 3 in-app purchases, starting at $0.99 per month. Frequency asks for nothing beyond the download.

Tuning Fork Studio holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Frequency has 340 ratings behind it against 1, so its average is the more settled of the two.

Frequency ships an update fortnightly, Tuning Fork Studio every 3 months. Both last shipped on October 18, 2026.
