  1. 4/5Needs better integration

    I use Garmin Connect with my Garmin watch for tracking everything as well as the Runna app for marathon training. I’m really enjoying the Fuelin app but it is really annoying and frustrating that I have to manually input every planned workout instead of Fuelin pulling that information from either Runna or my Garmin calendar. Runna pushes my planned workouts to Garmin but for some reason Fuelin isn’t able to grab that information. I also use an AI coach called Rest or Train that has all of my info from Runna and Garmin. Fuelin has a great concept but still lots of work to do in the integration department! It also seems glitchy when entering my upcoming runs/workouts. In the beginning I wasn’t able to enter planned mileage but Fuelin was able to fix that problem. Now I’m having trouble getting dates to “stick”. I have to enter the date several times in the process of adding the manual activity or it just reverts back to today’s date. Very annoying.

  2. 5/5Conquered my 70.3 because of this app

    I’m a 30‑year‑old guy who’s crossed the finish line of two half Ironmans and has learned the hard way that training your body is only half the battle—how you fuel it is everything. That’s where the Fuelin – Performance Nutrition app came in and completely changed how I eat and recover. Here’s why I’m giving it 5 stars: • After a long race weekend one weekend and a heavy bike/run brick the next, Fuelin updated my macros and meal suggestions that same day so I didn’t feel like I was guessing, under‑fueling or overdoing things. • The new Smart Meals feature has been a total game changer. I’ll glance at the suggestion and see exactly what I should eat, when, and how much—no more staring at my fridge wondering “okay, is this enough carbs for recovery?” • Logging meals is actually painless now. I talk or type what I ate, scan a barcode, or sync with whatever I already track—nutrition tracking finally works with my life, not against it. • It’s not just about race day—it gives me support for everyday training, recovery days, hard sessions, and those “just want energy and no gut issues” days. • I’ve noticed better recovery, more consistency in how I feel on training days, and fewer “why are my legs dead two days later” moments. If you’re a serious athlete (endurance, triathlon, long rides/runs) and you’re done guessing or winging your nutrition, Fuelin is by far one of the best decisions I’ve made for my performance. Highly recommend.

  3. 2/5Not really ready for everyone

    I’m a marathoner. I wanted to try Fuelin to see if it could help me dial in my nutrition this training block but they don’t give you any test run option (unless someone invites you with a 7 day trial). So now I’m stuck with it for a year. I’m an intuitive eater and my weight has stayed within a 3lb fluctuation for 11 years. My overall composition (muscle/fat) might change based on training but my weight is the same. Here are my issues with Fuelin: It only syncs with training peaks so if you’re not on TP, you enter your workouts manually and have to guess what zone 1-5 is. If I use what Strava is telling me, Fuelin underestimates my calories. I put in a 70 minute run that Strava said was Z2 and a 45 minutes strength session and my overall calorie recommendations for the day didn’t change. Also no option to manually add your own snacks. I emailed customer service after 5 days of trying it and got a lot of run around and a response from a dietician that just felt like someone put my concerns and questions into chatGPT. I think it’s not ready for anyone except triathletes using Training Peaks and also, it’s trying to train AI to replace real RDs.

  4. 5/5Can't live without it anymore

    I've been using Fuelin for about 3 months now and it's completely changed how I approach my nutrition as a runner. I'm training for my first marathon and was constantly struggling with energy crashes during long runs and not knowing what to eat for recovery. What sets Fuelin apart is how it actually understands my training schedule. It adjusts my nutrition recommendations based on whether I'm doing an easy 5-miler or a 20-mile long run, which seems obvious but no other app I tried did this. The portion sizes and macro targets shift with my workload, so I'm not undereating on hard days or overeating on rest days. The new smart meals feature is a game changer. Instead of just telling me to "eat 45g of carbs," it suggests actual meals that fit my targets. This morning it recommended overnight oats with banana and almond butter before my tempo run, and it was perfect. I love that I can swap ingredients based on what's in my fridge, and it recalculates everything instantly. The app also considers my biology - it asked about my menstrual cycle and adjusts recommendations during different phases, which has helped tremendously with cravings and energy levels. Small detail but makes a huge difference. If you're serious about your training and tired of generic nutrition advice, this app is worth every penny. My performance has improved, I have way more consistent energy, and I'm not constantly Googling "what to eat before a long run" anymore. Highly recommend!

  5. 4/5Mostly good in first two weeks, but unable to delete duplicate Strava imports

    Been using Fuelin for two weeks. It’s doing a great job helping me manage when and how much to eat to support my Ironman training. One large problem i have is that once an activity is imported from Strava, I cannot edit or delete it. This is a problem when my bike computer feeds Strava, but my Apple Watch does also. There are reasons I allow both devices to export to Strava, and I always delete one of them in Strava within a day, but I find that Strava and Fuelin sync both, then the Fuelin plan counts them as different Activities and adds the calories to my fuel plan which gets out of whack. I have not found a way to delete the duplicate activity from Fuelin. I intentionally allow the dual uploads to Strava for the sake of keeping my Apple “stats” complete, plus to avoid missing a workout when either my watch or bike computer battery dies.
