PasserBy
Read full descriptionHide full description
Wherever you are in the world, finds nearby places of interest and narrates “on your left…”. If one exists, it shows you a photo. Looks further ahead if you're travelling faster or closer in if you’re walking for example. Works with the screen turned off so you can put in your ear phones, slip your phone in your pocket and have PassingBy tell about the interesting places on your left, right or ahead as you stroll along and enjoy the scenery

Verdict
The clearest difference is in-app purchases: PasserBy at none against Guide.AI's 10. PasserBy also leads on update cadence (every 5 days vs every 3 weeks). Guide.AI's advantage is iOS requirement (12.0 vs 26.0). On price, ads and device support there is nothing between them.
