a subscription fee for this? are you kidding me? no thanks. to be clear 95% of the app is pay walled, so measuring the ppfd of the sun is the only thing it does without a MONTHLY SUBSCRIPTION. and then they have the nerve to reply like I have misunderstood. I wouldn't give these people one cent if I were you.

my tablet doesn't have the optics for this app when I get a reading of 2500ppfd on a 19watt. erd blue LED. it leaves me wondering if it's my tablet phone or the app. maybe it works on other phones but it's of no use to me.
One day...PPFD at 300-350 Next day...PPFD at 400-600 All over the map. Another app is more accurate and consistent.
App never provides accurate readings on my android phone even when calibrated.
I have subscribed then also demanding for money, when I opened app and click for PAR reading, app againg asking for money, why??
All that diffuser bollox, terrible app used to work well. total trash now, another sell out.
Too confusing to understand the readings and doesn’t tell you if is shade or full sun just a numberreading that stays wildly in flux. Pop ups to buy a diffuser or to buy premium services prevent you from using the app in any significant way and apparently you have to buy a diffuser to actually get any readings that are accurate so in general a fail from the start.
way off from an actual meter. this was showing 300-350. actual light meter showed 1000+. same distance.
I uninstalled 2 minutes after downloading. app is for a product and not a standalone app
2 months ago i got it with light sources available for free ....after the tease ..they want we to consume .....damn consumerism ! big disappointment..!
Used to be ok... The only plus was the PAR meter, which option is not free anymore... :S Also you can't see what you're measuring in because you can't get rid of the diffuser info panel! ...so I just uninstalled it and will use another app which is more user friendly!!
