This app is a game-changer for endurance athletes!" - Colleen Baker (Gravel Cyclist) "Helps me build awareness and healthy habits, removing the worry and helping me keep on track!" - Rob Castaneda (Age Group Triathlete) "Before finding Fuelin I wasn't aware that a system existed that could accurately account for my training on a day to day basis based on the training my coaches set for me. It just takes the guesswork out of the whole process and has empowered me to properly fuel my body. I've felt increased energy, better recovery and more consistency. Also, practicing my race nutrition in training has led to greater confidence in my plan and becomes more second nature so that I can make sure l hit it in a race.” - Holly Lawrence (Pro Triathlete) ________________________ Medical Disclaimer: Seek a doctor’s advice in addition to using this app and before making any medical decisions Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ U.S. Barcode Food Database Powered by FatSecret: https://fatsecret.com International Barcode Food Database Powered by Open Food Facts: https://openfoodfacts.org }

I am so disappointed with this app. Everything about it is just AI. You can even tell their emails were crafted straight from Chat GPT. The meal targets are stupid. For example, an afternoon ‘snack’, I’m supposed to target 40g protein, 0g carbs, 0g fat. But also, I’m supposed to eat fruit for said snack. That is literally not possible.

Over the years, one of my biggest challenges as an endurance athlete has been getting my nutrition right. I’d struggled with low energy availability, constant niggles and sickness, and the feeling that I just couldn’t back up training session after training session. No matter how hard I worked, my body wasn’t keeping up. Fuelin completely changed that for me. Fuelin reads my training program and gives simple, clear macro recommendations and fuelling timing for every session. It takes all the guesswork out of my day — what to eat, when to eat, and how to support the workload. The app is super easy to use and adjusts instantly whenever life forces a change to training (which, let’s be honest, happens all the time). Since using Fuelin, the difference has been huge: • My consistency has dramatically improved • Recovery feels quicker and more predictable • My mood and overall energy are better • And for the first time in a long time, I’m actually starting to shift weight in a healthy, sustainable way Fuelin has allowed me to train the way I’ve always wanted to — strong, consistent, and capable of showing up day after day. I can confidently say it’s been one of the most impactful tools in my performance journey, and I’m proud to have them as a partner at M5 Performance. If you’re an athlete who wants to train smarter, fuel better, and feel more in control of your body, I can’t recommend Fuelin enough.

Understanding nutrition, how to fuel and when is what has been missing for me in my training. I love how much I’m learning from using Fuelin and how much better I’m performing and recovering now that I’m focused on what my body needs.

I had a nutrition coach years ago (when I trained for an Ironman) that gave me my macros for certain times of the day. No explanation or teaching. Just “do this and if you do this training, do this”. Now getting back into triathlon training along with heavy lifting, I needed a personalized app that took my planned session from TrainingPeaks and prescribed what to eat and when. Being a scientist and an older female in my 40’s, I know nutrition and training need to match otherwise more muscle catabolism will continue at a great rate. This app and Scott Tindel and staff know this and have built this into the app. If you want to get the most from this app, listen to the podcasts, plan your workouts, and eat the prescribed macros at the given times. You will understand that this is more than just an app… it is a blueprint of how to get your engine from mediocre to premium!

I am sixty, most of us do not loose weight at this age, but with this Fuelin’s guidance I lost 14 lbs. I also qualified for 2026 70.3 WC while using this app. I’ve continued to use it every day and will do so for the foreseeable future. It’s not perfect but I will be forever grateful for the help.

This app is a disaster — very poor interface, no Strava connectivity, extreme focus on weight loss. impossible to find settings for flexibility eg to adjust the timing of imported Final Surge workouts. Very clearly mostly AI wrapped text boxes with good marketing. Even cancelling involved chatting with an AI boy just to be told to use Apple subscription management. I won’t be back.

Customer service is pretty responsive, which is a good thing because I’ve had to contact them more than once because the app keeps experiencing an error and they have to reset something on their side. I’ve already canceled the annual subscription I purchased. It would be nice if it actually worked without having to contact customer service.

Fuelin has taken the guesswork out of nutrition in triathlon training. It integrates with my Training Peaks account to give me not only macro targets, but also timing of meals. There is an option to set weight goals, ie weight loss, weight gain etc. so you can track that in one place as well (I used to use LoseIt for weight loss goals but it’s starting to look like I will be using Fuelin for lots that I used to use LoseIt for) The UI is very comprehensive and although there’s a bit of a learning curve it is absolutely worth it. There are AI features that can come up with meals and recipes using either what you have in the fridge and pantry already, or brand new fresh recipes that’ll hit your macros exactly. Excellent app. Try it.
