I have been spending some time recently with an AI coach targeted at the mental game. The Inner Game app attempts to take the ideas Timothy Gallwey introduced more than 50 years ago in The Inner Game of Tennis and turn them into an interactive mental-performance coaching platform.
The connection to Gallwey is considerably more substantial than an app developer simply borrowing the name of a famous tennis book. The product was developed with Gallwey’s involvement and draws from his books, recordings, writings, and other archival material. That provenance was one of the things that made me interested enough to try it. The Inner Game of Tennis remains one of the foundational books on the mental side of the sport, and I was curious what would happen when those ideas were combined with generative AI.
One of my first observations is that The Inner Game app is not tennis-specific. Considerable effort has been made to generalize Gallwey’s concepts across all sports. That makes sense from both a philosophical and commercial perspective. Many of the ideas in The Inner Game of Tennis were never exclusively about that sport in the first place, and Gallwey subsequently applied them well beyond the court.
Still, the lack of sports specificity has occasionally been off-putting. At one point, I actually asked the chatbot coach whether it knew anything about tennis. Its line of questioning had wandered far enough from the realities of my situation within the sport that I harbored serious doubts that it did. To be fair, I am still relatively early in the process. The entire premise of personalized AI coaching suggests that some value should come from the system learning more about me over time.
Part of the app operates on a calendar basis, prompting users to enter upcoming events. For me, the next significant competition is 55+ Mixed Sectionals that starts the day after this review goes live. The AI coach used that information to ask me why I felt shaky about the event. That left me wondering why it even started down that path.
I have no particular trepidation about playing 55+ Mixed Sectionals. That doesn’t mean there aren’t mental aspects of my tennis worth exploring, but inventing anxiety about an event so we can discuss why I am anxious isn’t especially useful. A good human coach who knew me would presumably discover my actual state of mind before deciding which problem we needed to solve. An AI coach that begins by supplying the problem risks steering the conversation somewhere it never needed to go.
That experience gets at one of the questions I am trying to answer during this evaluation. Can the chatbot learn enough about me to become genuinely personalized, or will it continue to try to wedge my experiences into its generalized mental-performance coaching patterns? I (literally) bought myself the time to find out.
The app begins with a seven-day free trial for first-time users. That wasn’t enough time for me to do a full assessment. A three-month subscription is $59.99, while the full-year is discounted to $191.99. I opted for the three-month option.
That ain’t cheap for an app, but more reasonable within tennis economics. Regional costs vary, but $191.99 is roughly the cost of two or three private lessons. I assume that ongoing mental-performance coaching from a live human would cost considerably more than that. That means that the relevant question isn’t whether $191.99 sounds expensive for an app subscription, but whether The Inner Game delivers enough coaching value to justify that amount compared with the alternatives available.
Compared with the cost of a book, however, The Inner Game is exorbitantly expensive if what users are primarily getting is a new way to consume Gallwey’s writing. I recognize that books are no longer the preferred way many people consume information, and an app can make the material more accessible to someone who was never going to sit down and read Gallwey in the first place. That alone does not justify the price. The interactive pieces need to add substantial value beyond repackaging the source material into videos, prompts, and chatbot conversations. For me, the next three months will largely determine whether they do.
The chatbot isn’t the only thing included with the subscription. The app provides daily prompts, lightweight journaling, videos, courses, and exercises. In fact, the video library was probably the deciding factor in paying for another three months. There appears to be enough material that I genuinely want to work through, and seven days wasn’t remotely enough time.
This also means I am beginning to think about the app as two related products. One is a structured digital delivery system for Inner Game material. The other is an AI coach attempting to apply those ideas personally to me. The first already looks promising. I am considerably less certain about the second.
I also have to confess that if this product had existed when one of my kids was playing junior tennis, I almost certainly would have bought it and insisted that she use it. Based on that fact alone, I suspect junior tennis could become a substantial market for something like this. Parents already spend enormous amounts of money on lessons, equipment, tournament travel, and everything else associated with developing a competitive player.
Mental performance matters, yet access to specialized coaching in that area is uneven. Some players have coaches and other resources that can help them develop those skills. Many do not. Technology potentially changes that equation.
An AI coach on a phone is not the equivalent of an experienced human who knows the player, understands the sport, recognizes what is actually happening, and can challenge assumptions based on a relationship developed over time.
The comparison gets more interesting when a human mental-performance coach isn’t an option. At $59.99 for three months, The Inner Game potentially gives a player access to structured material and individualized interaction at a fraction of what ongoing human coaching would cost. It doesn’t completely level the playing field, and I need further evaluation before hazarding any guess about how much of that gap it closes.
Seven days with the app was only enough to form an initial impression. It wasn’t enough to determine whether an AI coach becomes meaningfully better after weeks of learning about the person on the other side of the conversation. To complete the evaluation, I bought the three-month subscription. At the same time, I also immediately canceled the automatic renewal. History has taught me that if I eventually stop using an app, I’m very likely to forget I am still paying for it.
I now have three months to find out if, where and how this new app brings value to me. I want to work through the video library, continue using the daily exercises, and see whether the AI coach eventually stops trying to solve problems I don’t have. Most importantly, I want to know whether combining Gallwey’s ideas with AI produces something meaningfully different from simply reading The Inner Game of Tennis and applying those ideas myself.
The Inner Game App is available for download from the Apple App Store and the Google Play Store. There also appears to be a browser-based interface, but it is an emulation of one of the mobile platforms.
