# Precision Watch vs Oscillo

The clearest difference is ads: Oscillo at none against Precision Watch's shown. Oscillo also leads on rating (4.9 vs 4.5) and update cadence (weekly vs every 3 weeks). Precision Watch's advantage is device support (3 vs 1) and iOS requirement (16.4 vs 26.0). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Precision Watch sells 2 in-app purchases, starting at $2.99 per month and Oscillo sells 5 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Oscillo holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Oscillo has 27 ratings behind it against 2, so its average is the more settled of the two.

Precision Watch ships an update every 3 weeks, Oscillo weekly. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
