EVTO 4 has refined the most popular EV trip planner app for phone sized devices. Plan trips on your phone with multiple waypoints. Explore charging options using the charger overlays, have EVTO decide where to charge for you. Save frequently-used locations like 'Home' to speed up trip planning. EVTO 4 is the only EV trip planner you'll need, and it's always with you.

EVTO is predominantly a subscription-based application, for both monthly or annual use. You can try EVTO for one week without commitment. With the free version you have all you need to plan day trips and you can subscribe to the extra features as needed.

The application takes into account your car's characteristics such as model, battery, charger, wheels, motors and tires along with your driving style. During planning the application collects en route weather, determines elevation gains/losses, uses wind speeds, temperatures, estimated speed, charging capabilities and your state of charge to help you discover the optimal trip with the least amount of total time expended.

You can save your trips* to be used over and over again, compare trips to each other using a variety of provided charts and graphs.

Standard Features Include:

• Optimized routing based on time
• Map based planning
• Automatic Supercharger allocation and charging times
• Trip limited to 500 mi / 800 km
• Add 3 stopover and charging waypoints of your own
• Automatic weather forecasts for route
• Weather energy calculation (temperature, wind, road conditions and precipitation)
• Show details of your trip
• Support for both phones and tablets
• Help on each panel and feature
• Graph energy (SoC) for the trip by distance

I really want to like this app and will continue to try to make it work for me because the potential is high. Two problems that I am struggling to deal with seem pretty basic but I’ve found no resolution in the help section. First, I can’t plan a long distance trip (>~20 waypoints) without it telling me I need to break it down into segments (I have the subscription). That would assume I know good ways to break up the trip, but not knowing where the optimal charging points are, I can’t do that. I would like the app to auto segment a large trip for me after asking how far/long I want to drive each day. Instead I have to build the trip manually by looking at another source for the approximate trip route then attempt to recreate that with supercharger stops in the app. Time consuming. Second, if I change the destination for a trip, the app seems to get confused and dumps all the charging points, even after telling it to refresh auto charging points. My only option is to delete the whole trip and start over again. Not ideal.

Update: developer very responsive and working hard to improve the app. Still needs refinement but the app is getting better all the time. Will continue to update this review as the app progresses.

Developer Response ,

The restriction on the number of waypoints is because of a maps restriction and the fact that EVTO uses weather and the weather forecasts would be wrong for a continuous trip of that many stops. You have the right idea in using the segment feature for dividing the trip into days, which will be easier for you to manage and also create the correct weather forecasts that will more accurate depict your energy consumption. See the Rangefinder on the main menu to help you decide where to segment a trip.

We are sorry the app caused a problem for you if you change the destination. Please use the Feedback Report on the main menu to help us resolve any problems you encounter or to give us ideas for future features you would like considered.

Best out there

This app estimates range better than Tesla’s in-car navigation. I use it for every trip we take. There are a couple of issues that, if fixed, would earn this app five stars. The first is the difficulty in changing aspects of the trip without starting over, and the second is that for some reason it’s not automatically adding supercharger stops. Hopefully these will be fixed with the next update. That said, this is my go-to app for trip planning.

Great with a few glitches

Great to plan longer drives and estimate battery usage, charging stops and length of charge at various stops. The onboard software won’t plan for more frequent, shorter stops but this one can, and the chargers can be sent to your calendar so the car can do the navigation to them. Has a few glitches here and there, the developer has been prompt to answer my questions and address issues when I bring them up.
