HYGO

The app is not useable after iPhone OS upgrade. It is ok the first time then black screen. need to cycle the iPhone power to open it again.

Hit or miss if it loads, usually goes directly to blank screen and if you keep trying it sometimes loads and works like normal

This app is pretty useful, but it would really be great if the dollars per kilogram feature worked. But I can’t figure out how to get it to work. Hopefully the can developer can chime in and point the way. In the settings, it looks like there is a way to set that option, but I don’t see how to save that option. With the cost of fuel being so expensive, a price comparative tool would certainly be very useful.

I just learned about this app even though I’ve had my fuel cell car for over a year. It is very useful so far and an excellent way to share information. Two more capabilities would make it a great app: - Ability to make locations “favorite” so they are on top of the list to facilitate access to info; and - A graphic of a stations hydrogen inventory over time, say a month, so that there is better visibility into availability. How many times have you driven to a station just as it was going offline due to lack of hydrogen? Maybe these features are there and I haven’t found them yet, I’m new to the app, as I said. But I’m really grateful for all the info already at my fingertips with Hygo. Edited: After hearing from the developer, changed to 5 stars. The capabilities I requested are there, in a fashion, which makes the app more useful. A longer inventory look back period would still help IMO.

The app does not provide the data that it states in the description

EDIT: The new version is nicely enhanced in both function and appearance, nice work! One feature I miss is the Busy Times graphic. It was helpful for planning. I’ve used HYGO much more than the cafcp.com mobile site. HYGO is essential for FCEV owners. And the infrastructure is getting more reliable lately. Hmmm. Having this info in the hands of drivers probably helps motivate the H2 distributors to stay “green.” (So to speak.) :) OP: Just got a beautiful 2021 Mirai. My new job is to hunt for hydrogen. Hygo worked well for 2 months before the purchase (to scope out H2 availability) and 2 weeks after purchase (to find online H2 stations for refueling). Suddenly my iPhone stopped trusting the app. Deleted and reinstalled, now working. Appreciate quick response from developer. Suggest the next version include “refresh” in addition to “online” and “offline”—as pausing to repressurize is normal and teaches patience. Serious dispenser or compressor trouble OTOH means “Go elsewhere!”

This is probably the only useful app for hydrogen fueling on Apple devices. It works pretty well too.

Great app for hydrogen status without launching cafcp or other websites. I would like though if the app supports CarPlay, so I don’t need to take the phone out of my pocket. 😁😁

HYGO is a MUST for any FCEV owner! It’s so accurate and easy to use. Cafcp.org is frequently incorrect with old info but HYGO is dead honest every time. I never head to an H2 station without checking HYGO first! It’s laid out well and and easy to understand. I especially love logging my miles per fill. That’s a very cool feature. HYGO should be preloaded in every FCEV sold! If you drive a fuel cell electric vehicle Hygo is a must!
