### 1/5 — Review

*2017-02-17*

Seems like a neat app but after I purchaser it I was never able to enter my location. It would just return the initial screen. Contacted support and they replied but not able to fix problem. So it was useless.

### 3/5 — Calendar function keeps crashing

*2025-01-09, version 4.5*

The app is beautiful and well designed but the calendar reminder function is completely broken, which is what I bought this app for. The app just crashes whenever you try to use it.

### 4/5 — Needs to show direction you're facing

*2016-06-06*

It's good for shooing times and directions. Would be greatly improved by adding a VR aspect. Also if the map would show the direction you're facing that would be great.

### 5/5 — Great App.

*2017-08-14*

I love your app, at first I difficulty enabling the GPS but once it got enabled it worked like a breeze.

**Developer response:** Hello,

when adding/editing just enable "Use current location (GPS)" to get current position when choosing the location. Its working perfectly fine on all my testing devices.

Best wishes

### 5/5 — Great for the price

*2016-11-13*

Compared to a lot of the other apps that do a similar thing this one stacks up quite well.  Especially when you look at the prices.  It could use a few enhancements but it is great at what it does.

### 5/5 — Great app!

*2016-02-02, version 1.7*

Fantastic app for photographers
