After sending him a video to demonstrate that the sense2 was unresponsive, he sent me a new one for free. ### 5/5 — Best pool gadget ever *2026-03-18* I have been using WaterGuru now for several years, first the sense 1 and then the sense 2, and I honestly have to say that it is the best thing that happened to pool care ever. Before, I always had trouble keeping up with all the testing and adding the right amount of chemicals to the water , and sooner or later my pool would turn green every single year. Since I started using WaterGuru, I never had that problem again and in the end it saves me money on chemicals and upkeep. I also want to mention their customer service here, which is really second to none. They are extremely fast to respond, very helpful and always come up with a solution , should there be a problem or issue. Great product, great support, what mare can you ask for. **Developer response:** Thank you so much for the amazing review and for being a longtime WaterGuru user! We’re thrilled to hear it’s made such a difference in your pool care and helped keep everything balanced while saving you time and money. We truly appreciate your kind words about our support team as well. If you ever need anything, do not hesitate to let us know. We'll be more than happy to help. ### 5/5 — Handy product, great support! *2026-03-12* I have had my water guru for about 2 years and love the daily updates! I get a push notification if there is an issue with the flow (especially helpful in the winter, we stay too warm to winterize but I’m not outside daily) or chemicals. It also tracks trends to help you manage. Recently, my unit stopped taking readings and the troubleshooting guides didn’t correct it. I contacted support through the app chat feature and was connected with Arnaud who was helpful and patient - he stayed with me as I tested the unit and confirmed it was malfunctioning and was able to check my data in the app. And then sent me a brand new unit! No hassle, no fuss. He even sent instructions to update to new unit (and keep my pool data) in the app. Easy and helpful. Thank you! **Developer response:** Thank you so much for sharing your experience and for being a WaterGuru user for the past couple of years! We’re really glad the daily updates and alerts have been helpful in managing your pool, and that Arnaud was able to assist you and get a replacement unit set up smoothly. If you ever need anything, do not hesitate to let us know. We'll be more than happy to help. – Your friends at WaterGuru. ### 5/5 — Don’t hesitate *2026-03-09, version 7.0.1* After owning a few different pools this is absolute game changer. ### 1/5 — Great concept but horrific device reliability *2025-12-30, version 6.4.6* Very high failure rate and unreliability of both s1 and s2 Update 12/25 - had two more devices become intermittent. They dry out a few weeks, Work then either drain batteries or totally stop functioning. Waste of money on units and cartridges ### 5/5 — Great product and even better service *2025-11-26, version 6.4.6* I have used this product for three years. I leave for four months each year and depend on this equipment to give me readings and recommendations. Most people pay for a service while they are gone and that can run 250 a month. I just call my friend that lives next door and ask him to add ?? Chemicals about every three weeks. This week the unit stopped working and Arnaud at Water Guru walked me though some tests and declared the unit faulty. Much to my delight he sent me another unit free of cost. It does not get any better than that. ### 5/5 — Best pool product! *2025-10-24, version 6.4.6* I’ve had a Guru for over two years and have referred several friends with pools and or spas. Works great. Tells you what to add to keep your pool or spa in perfect condition. No drops to add to change colors. Then you have to figure out what to add. It’s so easy. The Guru tells you what to add and how much. And their customer support is outstanding. Arnaud walked me through an issue I had reconnecting to the Guru. Problem solved! Can’t recommend them any higher! ### 2/5 — tries too cheat you *2025-10-19, version 6.4.6* red alert change cartridge now when days left, total scam ### 1/5 — Want to love the product. Unfortunately it does not deliver on its promise. *2025-10-13, version 6.4.6* The idea of automated pool testing is fantastic. Such a time saver…if it worked. Had the original unit with 2 test cartridges. It worked relatively well until unit gave out. Made the rash decision to purchase the second gen model for the c5 cartridges. 5 tests in one seemed like a game changer. Problem is only chlorine and ph are accurate. The other 3 are nowhere near accurate nor precise. It seems like the app and the unit just randomly guess at calcium, alkalinity and cyanuric acid levels. The company still sells and advertises for accurate c5 cartridges, yet publicly told me the 3 don’t work well. They are working on a new design and were supposed to launch in July. It’s mid October and no update. Save the hassle and look elsewhere. ## Frequently asked questions about WaterGuru ### What does the WaterGuru app do?
