Ratings and Reviews

It’s not my repertoire

It’s not my repertoire to give thanks and praise for good service that I expect and deserve. But in the case of Chimani I will make an exception; their service and communication is without fault, almost instantaneous; the information provided in accurate and up to date, the app the most useful of all, nothing comes even close. The yearly membership was given too me as a gift, a gift that keeps giving and giving. If your a US traveler, purchasing this app with all the benefits, services and discounts it provides is a decision you will never regret. Money well spent and wisely. Ralph, NJ, USA

Dollar sign markers

It would be nice if there was a way to toggle on and off the dollar sign markers that offer discounts nearby parks. They cover up the actual park markers and make it hard to see what I’ve visited. Example: I went to Acadia and marked that as visited, which turned the marker orange, but I can’t see it on the map unless I zoom way in. It is covered by all kinds of dollar sign markers when zoomed out.

Provisional rating

Confiteor: my original rating with this review was 1 star. The app developer reached out in an effort to help me use the app. I am provisionally changing my original review at this time because our planned visit to Yellowstone is not until summer 2019. I am upping the rating to 5-stars for now based upon the responsiveness of the developer. I strongly believe in supporting developers for great products.
I am appreciative for apps which allow the interested person a trial period before deciding if they want to keep and use the app.
The free trial period is very brief for this app so be advised.

The developer is very responsive and interested in improving the app for the user.
