# OpenDisplay vs NinoPad

The clearest difference is in-app purchases: OpenDisplay at none against NinoPad's 3. OpenDisplay also leads on ratings volume (18 vs 1) and iOS requirement (15.0 vs 17.0). NinoPad's advantage is rating (5.0 vs 4.7) and update cadence (every 4 days vs every 8 days). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. NinoPad sells 3 in-app purchases, starting at $0.99 per 7 days. OpenDisplay asks for nothing beyond the download.

NinoPad holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OpenDisplay has 18 ratings behind it against 1, so its average is the more settled of the two.

OpenDisplay ships an update every 8 days, NinoPad every 4 days. The most recent releases landed on October 24, 2026 and October 11, 2026 respectively.
