Verdict
The clearest difference is rating: Coban at 4.8 against Context's 4.3. Coban also leads on ratings volume (619 vs 12) and update cadence (weekly vs every 3 weeks). Context's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Context sells 2 in-app purchases, starting at $3.49 per month and Coban sells 5 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
Coban holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Coban has 619 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 64% of Context's written reviews are positive against 81% of Coban's.
Context ships an update every 3 weeks, Coban weekly. The most recent releases landed on October 13, 2026 and October 20, 2026 respectively.
