Move! Move! It moves! You can draw and move your graphs! Setting invariables in the formula and changing the value, you can move your graphs freely! AMAZINGLY MANY KINDS OF GRAPHS! You can draw many kinds of graphs by setting function such as y=f(x), x=f(y), x=f(t) and y=g(t), f(x,y)=0, pole equation. MOVE GRAPHS! This is the greatest feature of this app! We prepared "m" as an invariable. You can change the value continuously and see the graph moving. Using this feature, you can see many interesting moves, such as simple oscillation, cycloid curve, synthesis of waves. ORIGINAL KEYBOARD! We prepared the original keyboard specialized for mathematical formulas. You can type mathematical formulas very easily. SEE MANY GRAPHS SIMULTANEOUSLY! You can set unlimited number of graphs and see them simultaneously. VERY CONVENIENT TOOL "com". By using this, you can draw line segments, circles, points and texts very easily. For example, you can draw a line segments by setting the starting point and the end point. MANY INTERESTING SAMPLES! You can load many interesting samples from “Load SampleCom”. They are not only interesting, but also help you to master this app. SAVE AND LOAD GRAPHS! You can save and load your original graphs! TAKE A PHOTO OF YOUR GRAPH! You easily take a photo of your graph by pushing “photo button”.

Verdict

The call

The clearest difference is ads: gDraw at none against 積分ガチャ's shown. gDraw also leads on price ($1.99 vs $5.99) and iOS requirement (12.0 vs 17.0). 積分ガチャ's advantage is update cadence (every 3 weeks vs every 2 months). On in-app purchases and device support there is nothing between them.
