Cancelled subscription ### 2/5 — Ads are so intrusive unusable *2026-01-22, version v12.04* I don’t mind having g to deal with ads if I’m using an app for free. The developers need to make a li ging too after all. However these full screen ads make the app essentially unusable. ### 5/5 — PPFD METER *2026-01-19, version v12.04* Just set it up !! ### 1/5 — Schlecht *2025-12-06, version v12.03* Bei jedem Klick Werbung. Gleich sofort wieder gelöscht! Einfach nur schlecht! ### 2/5 — Ads with lifetime premium purchase *2025-11-03, version v12.02* Why I’m I getting ads now, even with the paid version. ### 1/5 — Werbeverseucht *2025-09-30, version v12.02* Gelöscht. ### 5/5 — Fr die beste App *2025-08-19, version v2.5* Ich hab alle kostenlosen Apps ausprobiert. Die hier ist mit Abstand das beste was man geboten kommt. Vielen lieben Dank. ### 2/5 — Too Many Questions No Answers *2025-04-07, version v2.2* I believe this app might be wonderful but unfortunately after two days of trying to find instructions I have just about given up. I have a new iPhone 16 Pro and there are no visual or video instructions even on Youtube. The directions in the app seem like they’re for earlier phones. Whether I use a diffuser or not when I aim my phone’s camera at my light I can’t read the PPFD. I have to hit a pause button, flip my phone over to look. I still have no idea if I am using the app correctly. ### 5/5 — Not sure why there aren’t very many reviews *2025-04-03, version v2.2* This app is fantastic. It does everything that paid grow light meter apps do and based on my quick research online, seems to be just as accurate as any of them. Works great for me ### 5/5 — Awesome app *2024-11-16* Great addition for your grow journey. ## Frequently asked questions about PPFD METER ### What is PPFD METER?
