# Context vs Polyidiom

The clearest difference is review sentiment: Polyidiom at 100% against Context's 58%. Polyidiom also leads on rating (5.0 vs 4.5) and update cadence (every 3 days vs every 6 days). Context's advantage is ratings volume (13 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Context sells 2 in-app purchases, starting at $9.99 per month and Polyidiom sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Polyidiom holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Context has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 58% of Context's written reviews are positive against 100% of Polyidiom's.

Context ships an update every 6 days, Polyidiom every 3 days. The most recent releases landed on October 12, 2026 and October 8, 2026 respectively.
