About

Gobulin

Read full description

I'm Gobulin, the little goblin who lives in your phone. I'm scared of water — terrified of it — so my nose is sharp: I can smell where it is and which way it's moving. Heading out? Ask me first. "Heh. Nothing around here. Go on." "Hey — hold on, it's just about past." No percentages, no radar maps, none of that. I hate being wet, you hate being wet, we're in this together — so I tell you the one thing you want to hear. Here's what I do: ・The moment you open me, I sniff where you're standing — is it about to come down? ・Tell me where you're going and I'll sniff that whole route ・Water's coming? I'll tell you to sit tight until it's gone ・Come back and tell me if you got wet, and I'll smell it sharper next time Put on a rain poncho and every rider looks like a goblin — you and me, same crew. If I can't smell it, I'll say so instead of bluffing. And if you get soaked, that one's on me.

Verdict

The call

The clearest difference is in-app purchases: Gobulin at none against Solis's 1. Solis's advantage is ads (none vs shown) and iOS requirement (17.6 vs 26.0). On price and device support there is nothing between them.
