# Co vs NIDDO

The clearest difference is rating: NIDDO at 5.0 against Co's 4.5. NIDDO also leads on ads (none vs shown) and review sentiment (100% vs 74%). Co's advantage is ratings volume (31 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Co sells 2 in-app purchases, starting at $6.99 per month and NIDDO sells 10 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

NIDDO holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Co has 31 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 74% of Co's written reviews are positive against 100% of NIDDO's.

Co ships an update weekly, NIDDO every 3 days. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
