  • Exactly what I needed! May 17, 2021

    By Caseybro
    I’ve been looking for an app to track my home power usage since I live with roommates and want to track my charging usage. There are several other apps that do this but all charge fees, this app does it wonderfully and gives lots of other helpful information like the electricity price based on your power bill, and how much you’ve saved compared to a gas car. Only wish I could change the mpg it compares it to, since my old car got 39 mpg and it compares it to a car that gets 28 mpg

    Pretty simple and straight forward. Not many options but if more people continue to use it could definitely grow
  • Great App to be aware of how much money saved! May 18, 2021

    This App connects to your Tesla account and shows in a live manner how much you are being charged by your utility company (~) when you are charging your car at home with your Tesla charger and beyond. It also compares the cost of an ICE comparable car (Like a BMW etc) to provide the cost of the filling a gas tank. Really loved the concept and it’s free!

    Great app overall. The only thing I would change is to display in real time if my car is being charged or not. Other then that, it's a great app to get the cheapest charging at home and to track your usage.
  • Amazing app Mar 7, 2021

    Really needed one of this kind of app that measures how much kwh charge my car took while charging. Also measure and keep eye on cost basis kwh takes while in charge. Now I can have accurate kwh cost takes my Tesla so at the end I can better have exact cost to tax file in miscellaneous. I really like this app and can recommend to any EV owners.

    Great app, does what it is designed for and does it for free. Easiest way to track what you have spent on charging. Customer support is next level. Developers are responsive and Ben did a great job helping me correct my rates.
  • Great even without time of use plan Dec 22, 2020

    By Dmurph24
    I’ve been using Optiwatts website for a few months and even though I don’t have a time of use electric plan I still find the analytics, preconditioning, and scheduling features extremely valuable. The app version is no different. Love it

  • Update: This App is great! Mar 20, 2021

    Had some initial issues getting it set up, it after those were cleared up, this app is pretty awesome! Very cool seeing how much I am saving and what I pay to charge my car at home! Recommend for any Tesla owner!

    Needs more than one charging location setting. I charge at home and at 2 work locations which I also pay for the electric.

  • Good thing it’s free May 17, 2021

    By Tph423
    On a positive note, the app did read odometer correctly. But it did not report accurate utility rate times, or reflect charging schedule already set in Model 3. I have no clue what pricing it uses for estimated gasoline savings. All in all, I deleted it as not useful.

    Charged my car to 90% when it was set to 70% On a separate occasion, it stopped charging my car way too early when though the power cost was negative. In response to the comment - I opened the app and it said 70 and the update button was greyed out. I understand that you might be showing 90 in your system but there may be a miscommunication from the UI to the cloud
  • Causes phantom drain and therefore more charging costs Jan 11, 2021

    By Dj Shiran
    In principle the app seems great but I went from very minimal phantom drain to a lot of phantom drain after installing and connecting the app. I reached out to optiwatt but after a week without response I am posting this review.

    Since I have downloaded app, I have had nothing but issues with charging my Tesla. Optiwatt had no support, and will not answer. DO NOT USE THIS APP..car charges all the time, schedule does not work, and no support available.

    Website and app look nice. Found my electric provider. But auth token login doesn't work, so I can't use this. 3 months after initial release and no app update, not looking good.

    This app has been great. Shows some neat data and handles my charging schedule for me.

    A great solution to home charging scheduling. It also tracks and records your usage at home.
  • Great App could be even better May 26, 2021

    I’d really like to be able to manually input supercharger events to track total monthly “fuel” costs.

  • Good basic features Jan 31, 2021

    By SDTravel
    Really needs to add Sign-in with Apple option.
  • Good concept Jun 1, 2021

    By deagia and dora
    It is great this app is free and does not collect data on you personally I don’t know if someone in China will log into my tesla account like on another app I got but so far no one has I also have some serious two factor athentication going so nothing will happen anyway.But I was really hoping that this app would have some ways to control at least the frunk so I could use in the NFC tag to open it I’m not looking to spend as much as an Internet subscription just to be able to open the front trunk because the Tesla app has a lack of features. It would be a great addition too this app to have controls at least for the front trunk and not cost a fortune.
