# NeuroSky Recorder vs Frequency

The clearest difference is review sentiment: Frequency at 73% against NeuroSky Recorder's 22%. Frequency also leads on rating (4.7 vs 1.6) and update cadence (fortnightly vs every 25 months). NeuroSky Recorder's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Frequency holds the better App Store score, 4.7 against 1.6. That said, the two scores are not equally well evidenced: Frequency has 1.2K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 22% of NeuroSky Recorder's written reviews are positive against 73% of Frequency's.

NeuroSky Recorder ships an update every 25 months, Frequency fortnightly. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
