# SPL Graph vs De

The clearest difference is in-app purchases: De at none against SPL Graph's 5. De also leads on ratings volume (19 vs 3) and iOS requirement (13 vs 15.0). SPL Graph's advantage is update cadence (every 6 months vs every 38 months) and rating (3.7 vs 3.4). On price, ads, monetization model and device support there is nothing between them.

SPL Graph costs $9.99 and De $9.99 up front. SPL Graph sells 5 in-app purchases, starting at $19.99 per month. De asks for nothing beyond the download.

SPL Graph holds the better App Store score, 3.7 against 3.4.
