# ECGsource vs AngioAID 3D

The clearest difference is price: AngioAID 3D at Free against ECGsource's $0.99. AngioAID 3D also leads on rating (4.0 vs 3.0). ECGsource's advantage is ads (none vs shown) and update cadence (every 4 months vs every 28 months). On in-app purchases and device support there is nothing between them.

AngioAID 3D is free to download; ECGsource costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
