Ratings and Reviews
Huge benefit for my half Ironman training!
Fuelin was a great app that helped me navigate my nutrition plan along with my workouts to have a successful first half Ironman! I didn’t have the budget for the one-on-one consultations but even on the low end of cost it was totally worth it: I listened to all the educational videos and as many of the live events as I could.
As an older athlete (41) doing her first long distance tri, I knew the importance of getting my nutrition on point to help prevent injury, sickness and help me perform at my best. Fuelin allowed me to do that on a tight budget, and I’ll be forever grateful. I was able to plan each day effectively and my body performed well and recovered well.
If I decide to do another long distance, I will definitely use Fuelin again and hopefully be able to go for the one-on-one consultation to get even more out of the program.
Unusable app with zero free trial, zero satisfaction guarantee
The app looked promising, but at the end of the day it’s another case of overpromising and under-delivering. I was initially sketched out by the lack of free trial—why wouldn’t you want users to understand the app before committing? But I went on the website and found a section where they explained their 90 day money back policy and bought the 1 year. I began using the app consistently for a few weeks, but found it buggy and impossible to log your actual nutrition macros. AI takes a stab at counting macros based on your description, but you can’t edit what it guesses, even when you’re staring at the nutritional facts. The barcode scanning rarely works. When I reached out to take advantage of the money back policy, I was ghosted for several weeks. Finally someone reached out to explain they have no such policy and told me I should instead be “all in”. I showed them where Google SEO had cached the part of the website explaining the refund policy (they took it off their site apparently) but I have been ghosted yet again. This app does not do anything that MyFitPal and similar does much better and with real customer support.
Fuelin guided me to a successful Half Distance Triathlon
Fuelin’s daily recommendations work! I have been logging my food daily and using Fuelin for over a year now. Fuelin provides daily recommendations on food consumption in sync with all of my workouts along with the proper Fuelin strategy for in workout consumption. Before using Fuelin I was did not consume much if anything during workouts and this app taught me the optimal amounts to consume before, during, and after workouts. Also following along with daily tracking I was able to maintain my energy and weight during all of the tough training cycles. I finished the Clash Daytona 1/2 Triathlon in the top 1/2 of my Age Group, powering through the very challenging run in the heat at the end. Thanks to the entire Fuelin team for their support and helping me achieve this milestone!
