### 5/5 — Great App!

*2022-07-06*

Simple, easy layout, easy to understand! Highly recommended!

Would be cool future development to show how long to be exposed to maximize Vit D without over/under exposure.

**Developer response:** Thanks a lot for your review. This is complicated to say precisely since it depends on other factors, such as skin tone, body clothes coverage, etc. But as a general rule, for a Caucasian type with arms and legs uncovered it should be enough 20 min. while the Sun is at 50° or above.

Cheers! :)

### 5/5 — Sun Angles for Maximum Vitamin D

*2022-02-04*

App is very easy to understand. Has angles, time periods and length of time the sun is at 45 or 50 degree angles. During Covid, this is the best app you can ask for. Developer is very responsive and cares about the app. App displays time of the day when the sun is at 45 and 50 degree angles to get the maximum sun exposure. Uses your location at the moment.

**Developer response:** Thanks a lot, my friend! :)

### 5/5 — Vitamin D deficiency is a global proble

*2021-09-15*

This is a great app to hopefully help people realize how to safely get the best ( natural) vitamin D. We would have much less illnesses if 80+% of the population wasn’t vitamin D deficient. I use it everyday during vitamin D season.

**Developer response:** Big thanks, my friend! I'm very happy the app is so useful for you.

### 5/5 — Great App

*2021-01-06, version 1.0.1*

This is one of those Apps that inspires and informs. The sun comes up and goes down every day and most (the significant most) have little appreciation of the angle, the importance of that angle, the seasons it thus generates. This is an educational and helpful App. More locations as an ability would be an amazing feature. Keep up the good work.

### 5/5 — Super Solar Guide

*2020-10-10, version 1.0.1*

This is an excellent App. 
I have a Motorhome and a couple of adjustable solar panels. 
Because this App knows where I am, it knows the precise angle of the sun at any given time of day, knows when it rises and sets, and knows when it will be at its Zenith. 
Tells me for how long it will be above a particular angle as well, which is also useful. 
This helps me adjust the angular position of my solar panels for optimum electricity generation. 
Until I get some super motorised panels which automatically track towards the sun, this is the next best thing. 
Easy 5 stars.

### 1/5 — Waste of money

*2020-07-24*

Not enough features. Would be better if you could view data for other locations + future dates. Quite useless
