Fortis – Workout Tracker, Training Log & Adaptive Coach
Fortis is the workout tracker and training log built for lifters of every background, powerlifters, bodybuilders, weightlifters, athletes, or anyone working to get stronger in the gym. Log every set, track your strength progression over time, and train alongside a real community instead of alone.
Most fitness apps make you choose: a flexible logbook with no guidance, or a rigid plan that doesn't adapt to your life. Fortis does both: a free, open training log built on your community, plus an adaptive coach that reads your progress and adjusts your program in real time.
Key Features
Log every detail with precision – Track exercises, sets, reps, and weight across every lift, every session.
Monitor strength progression – See your e1RM trend and performance history for every lift, automatically.
Seamless workout sharing – Post full workout details so your training partners see exactly how you train.
Get coached, not just tracked – Fortis Premium catches plateaus before you do and adjusts your program to keep you progressing.
Train your way – Powerlifting, bodybuilding, Olympic lifting, or general strength training, Fortis adapts to your program.
Stay consistent when life gets busy – Premium's flexibility layer moves your training days around your schedule without losing progress.
Train Smarter, Together
Strength training doesn't have to be a guessing game or a rigid script. With Fortis, you build your training log alongside a real community and get an adaptive coach that steps in the moment your progress stalls, so you stay consistent, keep progressing, and don't burn out.
Whether you're chasing a new squat PR, refining your technique, or just staying consistent in the gym, Fortis gives you the tools to track, train, and grow, with a community behind you and a coach in your corner.

I love this app because it helps me SEE and SHARE my progress, without trying to over engineer the way I actually track it. Look, there’s no getting around the work of writing down my sets and reps or the length of my run or my tennis match. Nor do I want there to be, because I enjoy that simple activity of logging. The need it fills for me is to quickly see my progress over time in a way that previously was not visible in my physical notebook or Notes app, and to share both that trajectory and some of the highlights - in the form of individual workouts that were especially meaningful - with the people I care about, including friends, family, and even new friends who share my passion for fitness. No frills and everything I need.
I love this app!

I highly recommend this app!! This app is the new up and coming socialmedia platform of fitness! Not only can you accurately put in your workouts, but you post them and get to connect with people from all over the world. Whether you are just starting your fitness journey or you are an advanced lifter, putting in your workouts is quick, easy, and way better than any other app I’ve used. Plus, customer service responds right away if you have any questions! You should definitely download this if you are wanting motivation to workout, to connect with others, or to just get pumped about fitness!
This has changed the game

I’ve been a powerlifter since high school and I usually just write down my lifts in my notebook. When I forget it or travel to a different gym I usually just lose those lifts. This way I always have it with me and it’s made progress so much easier to see over time. I also love being able to see what kind of workouts my friends are doing too. Way easier to use than Hevy or Strong!!
You should download!

I’m someone who loves working out and tracking things, so I was excited when I learned about Fortis. I love the connection aspect. The app works really well but here’s a few things I think could make it even better: - the bio feature: every time i press the space bar it reverts to capital letters (like when you start a new sentence), idk if that’s just my phone - I think it would be cool to have a community feature where you can post either to following feed or to everyone with motivation, tips, etc. you can go to others profiles and see their posts. Etc. - possibly more customization for workouts. Like sports, or home workouts, etc. All in all it’s a really great app and I can’t wait to use it more! Definitely give it a try!
