Introduction
Introduction
TRNR is a personal passion project of mine I have been working on in spare evenings and weekends. The idea came to me during a session with my personal trainer Cory. I realised that he was still resorting to the notes app on his phone to track my workout & fitness progress. As I client I would have loved to see my progress across time as well as being able to track workouts myself when not in a paid PT session. I was using 5 different apps (My Fitness Pal, Strong etc) to track my progress, all of which Cory had no access to. I had an in-depth chat with him about what feature set he would love to see in an app that he could use to run his own coaching business and that clients could also have access to. I got to work straight away building what has become TRNR. The one stop shop for personal trainers to run their entire coaching business in one place. From automated invoicing and accounts to tracking workouts, client nutrition and selling services online to expand beyond face-to-face clients and make money as they sleep.

Challenges
Challenges
During the projects initial design I conducted some market research online and by interviewing other personal trainers. I soon realised the app concept already existed and had businesses that were thriving financially. This proved the market demand and excited me more. Analysing compeditors I relaised there was a plethora of options but the quality of the software from a UI/UX point of view was severely lacking.
Interestingly fitness apps targeted at consumers had all of the thoughtfulness and care poured into their design but apps targeting the B2B side of the market like mine were built at best, like functional tools. A trend I have seen through-out my career. This combined with utilising AI in a way that had real impact in saving PT's time and money would be my key market diffientiator. The project is now launching this summer (2025) after nearly 3 years in development on weekends and evenings. I knew that if PT's were going to use my software for every aspect of their business from invoicing to day to day interractions with clients that it had to not only work from day one but work flawlessly, exceeding compeditors that have 60+ staff. What motivates me pre-launch is that in the beta testing phase I have had incredible feedback from trainers who use compeditors. These compeditors have huge overheads, are slow to move and require thousands of trainers to reach a monthly recurring break even point.
