I downloaded the app, paid for a month just to see if I would like it and if worked as I needed. Immediately the app said purchase failed but my app account said I was already subscribed. I tried to wait and see if it would catch up but every time I tried to use the app it would push me to the subscription prompt again. I promptly deleted the app and am now writing this. Enjoy my $4.99. It got you this review. -- Mrs.dmfz, 2026-07-13 [View all Par Meter reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Par Meter In-App Purchases | Item | Price | |------|-------| | Pro Monthly | $4.99 | | Weekly Pro | $3.99 | | Yearly Pro | $29.99 | ## Par Meter Discovered Keywords - plant light meter - grow light meter - light measure - free light meter - light meter for plants - light meter plants - ppfd meter - par meter - light intensity - ppfd monitor ## Par Meter Available In - [United States](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/united-states) - [Australia](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/australia) - [Brazil](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/brazil) - [Canada](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/canada) - [Chile](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/chile) - [Czechia](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/czechia) - [Germany](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/germany) - [South Korea](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/south-korea) - [Lithuania](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/lithuania) - [Malaysia](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/malaysia) - [New Zealand](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/new-zealand) - [Ukraine](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/ukraine) - [Italy](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/italy) - [Armenia](https://apptail.io/app/par-meter-ppfd-monitor-fGqy/armenia) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
