I can’t use this app & I’m forced to constantly use pico screen which is inconvenient. ### 1/5 — Update now broken *2025-10-19, version 1.3.1608* Not that it was great before but at least it mostly worked. Now I can’t get past the load screen telling me all the problems it has fixed. Helllllppppp!!! ### 1/5 — Unable to access app since upgrade *2025-10-15, version 1.3.1594* Since updating to v1.3.1594, when I open the app a screen of information appears that I can not click out of. The app is now useless. Was working well before the update. PLEASE FIX!! ### 1/5 — Useless app *2025-06-26, version 1.2.1379* Same problem as others, won’t connect. Goes into endless “mandatory firmware upgrade” loop. Totally useless app. I wonder what bugs they fixed since I last tried - didn’t work the, doesn’t work now! ### 1/5 — What a Waste of Time *2025-06-01* Where do I start? The app has only connected for me once, I spent a lot of time shutting the device off and on, my phone off and on, my Wi-Fi off and on, forgetting the Wi-Fi network, deleting and reinstalling the app, etc. etc. Finally I gave up. I turned the Wi-Fi on the device off, and I deleted the app. What a waste of time and a shame they don’t fix this, as there are no positive reviews - the app was part of the appeal for purchasing a really expensive system, I’ll add my voice to the others (years old) asking you to fix this. ### 1/5 — Oh no! *2025-05-18, version 1.2.1379* Updated the firmware and now can’t see Pico on the WiFi at all. Big mistake ### 1/5 — Totally useless app *2025-04-22, version 1.2.1379* App just locks up on opening screen. Simarine is a great product but desperately needs a monitoring app that works. They just don’t seem interested in fixing it ### 1/5 — Complete rubbish *2024-11-22, version 1.2.881* Difficult to use and setup and conection is shocking if it ever connects worst app ### 1/5 — Hopeless *2024-04-28, version 1.2.806* Does not connect. App won’t even let you go to settings when it is disconnected. Shameful and a very poor reflection in the Simarine brand. ### 2/5 — Not much works in this app, is it still supported? *2024-04-25* Nothing seems to work on this app, settings button is in operative and data shown is not the same as on my device. When will this be fixed? ## Frequently asked questions about SIMARINE ### What does the SIMARINE app do? The SIMARINE app allows you to remotely monitor your boat's power usage and tank levels.
