### 1/5 — Hard to use

*2025-11-17*

Very hard to use this app, not user friendly and UI is bad

### 1/5 — Doesn’t really work well

*2025-11-09*

Wanted to view railroads and while it would show them for the United States zoomed out, as soon as I zoomed into south east Florida, no go.

### 2/5 — 5 stars if it worked

*2025-08-16*

Worked a few months ago. Can’t load after 5 seconds of use.

### 1/5 — Won’t load after a few minutes of use

*2025-06-30*

I love this app for exploring but after a minute or two of use the app stops loading in the map and i am forced to restart.

Edit: changed from 4 stars to 1 star. this app has become unusable, map wont load

### 1/5 — Won’t load after a few minutes of use

*2025-06-28*

I love this app for exploring but after a minute or two of use the app stops loading in the map and i am forced to restart.

Edit: this app has become unusable

### 1/5 — No navigation

*2025-02-28*

This map app is categorized under “Navigation” but it doesn’t actually have that functionality, so if you have someone else manually looking at the screen to tell you which direction to drive, like back in the day of paper map books, maybe you will find it useful, but for me it’s just another OSM viewer, and OSM is too incomplete, and often wrong due to being updated only by volunteers, that this is a useless app.

### 1/5 — Not using OSM

*2025-02-15*

This doesn't seem to be using OSM, but the maps from Apple. Gulf of America??? What is that???

### 1/5 — Gulf of America?

*2025-02-12*

Forget that. I’ll use another map that has the correct name for major bodies of water

### 2/5 — A little clunky but better image

*2025-01-19*

Better than open maps that it does busniess searches , but no gps is okay, use Waze or a GPS guidance app for that that does traffic without centralization of roads etc

~

### 4/5 — Gut aber Kleinigkeiten können noch besser sein

*2024-11-19*

Eine wirklich tolle App. Ich nutze sie sehr gerne und sehr oft. Aber ein paar Kleinigkeiten, zum Beispiel die Einblendung der Legenden der Overlaydaten fehlen noch. Und das caching behaviour ist manchmal ein bisschen erratisch. Außerdem gibt es einen Beschriftungsfehler bei der Openrailwaymapoverlay
