### 5/5 — Indispensable app for those who take their health seriously

*2026-08-18*

Fuelin has become indispensable in my health and cycling journey. As a 67 years old master cyclist who is overweight, Fuelin is an indispensable tool not just to track what I eat but to know how to properly fuel my body to be successful in my sport. 

One of the hardest things to do when you are trying to lose weight while building fitness is to know what to eat. I love that Fuelin suggest what should I eat for each meal when I am training or racing. And if I have one ingredient, let say a chicken breast, Fuelin builds a recipe around that ingredient that perfectly matches the macros for that meal.

Because Fuelin syncs with Training Peaks it knows when my races are and creates a plan for carbo loading for the week of the race.

### 1/5 — Interface stops working immediately upon cancellation

*2026-08-15*

I am still in the middle of a month that was paid for, but was on the fence about continuing a $30/month subscription and pre-emptively cancelled in the middle of the month to avoid getting charged next month when I really hadn’t yet made up my mind about how useful the app was going to be for me.  Immediately, the app lost functionality to interface with my Garmin workouts and won’t refresh data.

I also hadn’t been in love with challenges using Lose It to log nutrition data and having that interface with Apple Health and then sync with Fuelin via that avenue, because it lead to incorrect macro data showing up in the Fuelin app.

If I was on the fence before about continuing the subscription, the abrupt failure of a service that I have paid for for a couple of more weeks to continue working for me had cinched the deal.

### 4/5 — Performance changing

*2026-08-12, version 2.2.4*

The first week using this app completely changed my performance in competitive gravel cycling. 

I have always struggled with Under fueling and questioned why I was not able to increase my mileage and performance. 

Now I am able to push my body further and recover faster with proper nutrition numbers. 

Also has saved me a lot of time that was wasted trying to think of something to eat or what to buy at the grocery store. 

Only thing I would ask differently is a change up of recipe recommendations.

### 1/5 — Wouldn't recommend for marathoners

*2026-08-09, version 2.2.4*

I downloaded the app to help do a double check on my fueling in peak marathon training. I was disappointed to see that even with a performance fueling setting , the protein requirements were well above standard recommendations (2.2g/kG+ vs 1.6-2) and carbs were low!! This is setting up marathoners for low energy availability. For example, it suggested I only have 30g carbs after a 13 mile run with 45 min tempo workout which is far too low. I would not recommend for marathon runners.

### 4/5 — Needs better integration

*2026-07-31*

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.

### 5/5 — Not just a fixed meal plan

*2026-07-29*

I love how Fuelin adjusts to my training and daily fluctuations. It helps ensure that I meet my energy needs for my cycling. It’s not just a meal plan, it’s basically a coach in your pocket available 24/7. 

Definitely recommend if you want to improve your performance and also manage body composition. Remove the guess work and trust the process

### 1/5 — Misleading free trial

*2026-07-28, version 2.2.4*

It gave me a free trial option. I tried it for a day and it wasn’t for me. I went to cancel my trial. It took me several questions and then it said I had to cancel it in my app subscription. I had none in my apps and I kept checking it. A week later it billed me. This time it gave me an option to cancel in my billing portal (which wasn’t available during the free trial).

### 4/5 — Fuelin

*2026-07-26*

This is a great app but it’s a bit confusing and maybe a tad complicated when you start using it. You have to invest a far bit of time watching all the videos and tutorials

### 2/5 — No free version

*2026-07-24, version 2.2.4*

I don’t have a problem with this being a premium app, but you should probably explain that at some point before you have people sign up and share their personal information. Seems like a way to just harvest personal information.

### 3/5 — Almost Great

*2026-07-21, version 2.2.4*

My main hesitation with this app is that my training plan in Final Surge does not sync to Fuelin until after the workout is complete, which then recalculates everything for the rest of the day. I thought that it would sync before in order to fuel properly before and during. It also wasn’t clear the options of AI or working with a human. Maybe this is beginner user error, but it’s not quite what I was expecting. I’ve used several macro apps, and this is basically the same as all the others. It may be a different story in the higher plan that pairs you with a human, but I don’t have the budget for that right now. I guess you get what you pay for!
