Idea type: Swamp

The market has seen several mediocre solutions that nobody loves. Unless you can offer something fundamentally different, you’ll likely struggle to stand out or make money.

Should You Build It?

Don't build it.


Your are here

The idea of a personalized workout and diet planner app falls into a crowded space. Our analysis identifies it as belonging to the 'Swamp' category, meaning there are already several mediocre solutions in the market, and it can be challenging to stand out. With 11 similar products identified, competition is high. The average engagement (comments) on these similar products is low. These metrics suggest that while there is a clear need for fitness and diet solutions, users are not necessarily excited or satisfied with existing offerings. To succeed, your product needs a fundamental differentiation to avoid being just another face in the crowd.

Recommendations

  1. Given that you are entering a 'Swamp' category with a high number of competitors, your first step is to deeply analyze why existing workout and diet planner apps aren't resonating with users. Scrutinize user reviews, identify pain points, and pinpoint unmet needs. Understanding the failures of others is crucial before investing further effort into development. For example, I built an app that personalizes home workouts received negative feedback about hidden fees and lack of personalization.
  2. Instead of targeting a broad audience, focus on a specific niche within the fitness and diet space. This could be a particular age group (e.g., seniors), a specific fitness goal (e.g., marathon training), or a dietary restriction (e.g., plant-based athletes). By catering to a smaller, well-defined group, you can tailor your features and marketing to their unique needs, increasing the likelihood of success.
  3. Rather than building a standalone app, consider creating tools or features that integrate with existing fitness platforms or apps. This approach allows you to leverage established user bases and avoid the challenge of acquiring users from scratch. Think of providing specialized workout routines or diet plans that users can import into their preferred fitness tracker.
  4. Explore related problems in the health and wellness space that may be less saturated and offer more promising opportunities. Perhaps a tool that helps users manage their mental health alongside their physical fitness, or a platform that connects users with local health and wellness providers. This could provide a unique selling proposition and set you apart from the competition.
  5. Prioritize user feedback and iterate rapidly based on their input. Launch a minimum viable product (MVP) with core features and gather feedback from your target audience. Use this feedback to refine your product and ensure that it meets their needs and addresses their pain points. Be careful not to charge hidden fees, as users in similar apps have complained about this.
  6. Before investing significant time and resources, validate your idea by conducting thorough market research. This includes analyzing competitor offerings, surveying potential users, and testing your value proposition. Ensure that there is sufficient demand for your product and that you can differentiate it from existing solutions. Consider incorporating a streaks/rewards system to enhance daily motivation.

Questions

  1. What is the one unique feature that your workout and diet planner app will offer that isn't already available in the market, and how will it drastically improve the user experience compared to existing solutions?
  2. Given the low average engagement observed in similar products, what specific strategies will you employ to ensure that users remain actively engaged with your app over the long term, and how will you measure the effectiveness of these strategies?
  3. How will you validate the demand and willingness to pay for your app within your chosen niche market before launching, and what specific metrics will you use to determine whether your product is resonating with your target audience?

I built an app that personalizes home workouts

Hey HN,I’ve built and bootstrapped PARIAN. It designs personalized workouts so you reach your fitness goal quickly and efficiently. By training only with goal-specific exercises tailored to your experience level and preferred equipment (or just bodyweight), you skip the wasted time, effort, and disappointment. No more doom scrolling exercises, being overwhelmed by how to plan them, and being bombarded by noise from all the fitfluencers. You workout with confidence knowing each exercise is intentional and each session is moving you forward. Plus, you have the freedom to customize your program at any moment, ensuring the training is enjoyable - thus ensuring consistency.I believe fitness is not a lifestyle, but a core part of life and wanted to create something that will assist this pursuit of going after your fitness potential. And instill the excitement of all the new doors that will open up - bouldering, boxing, breakdancing, you name it. Being non technical I naturally leaned towards no-code platforms. Started building on Bubble in 2022 and launched the demo that December. I got some assistance from friends with html, css, and js along the way and officially launched the MVP in Feb 2023.The fitness app space is crowded, and ones that tailor workouts already exist—so why build this? Saturation is demand, and it’s easier to stand out in a crowd than to create your own market. When you break it down, most of the apps aren't personalized. Majority are workout trackers/loggers or just have a selection of pre-made workouts.The few apps that do personalize workouts create subpar programs with surface level tutorials and lack support, guidance, and customization.Additionally, even the most popular apps in this space have: — Questionable exercise selection — Exercise redundancy in the workouts — Excessive training volume — Require constant input throughout workoutsThe gap between 0 support and minimal structure (youtube/pdf plans), and hiring a personal trainer at a gym for hundreds of dollars is huge. While both have their time and place, I believe most would actually benefit working out with an app. Training from home, with bodyweight/available equipment is the fastest way to start that fitness journey - leveraging the device you spend the most time with. PARIAN is more than a workout tracker & planner - it’s a savvy training partner that guides you through personalized workouts and expedites your fitness journey.Just shipped an update, try a demo workout here — https://parianlabs.com/demo-workoutsFollow our journey — @parianlabs on instaFeedback and support is much appreciated!

Users expressed frustration over a hidden fee, account deletion issues, and unclear value proposition. Some found the UI unresponsive and had trouble with mobile layout. Positive feedback included excitement for StretchLab, preference for generated videos, and willingness to pay despite script requirements. Minor issues with navigation and demo links were noted. Comparisons with other services' pricing and a dramatic endorsement were also mentioned.

Users criticized the product for a hidden $10 fee post-account creation, account deletion issues, and lack of UI feedback for deletion. The value proposition was deemed unspecific and lacking personalization. There were complaints about the gym's bench shortage, excessive padding affecting mobile display, poor mobile optimization, and script requirements from major platforms. The navigation bar was reported as too squashed on desktop, and the $10/month fitness service was called delusional.

This is great feedback! You're 100% right that the value proposition is personalization and it's crucial to effectively communicate this to users in a tangible way.I'm actually now going to implement a $1 1-day trial. Prior to discovering YC I was initially was going to have the webapp free, but as they often preach free products mute signs if you're actually hitting the PMF. The trial will act as a filter between those who are genuinely curious about the product, and those who are just browsing and probably wouldn't have ever paid.Your dream app literally sounds like PARIAN after the next update. The app currently does most of what you've listed:- personalized plan based on profile, custom goals and equipment - easily customizable workout plan that you can add/remove exercises from - comparable exercise suggestions (coming soon)The idea I have for this comparable exercise suggestion is you will be able to do it in just a few seconds with a feature called "Swap" right in the workout pageSay you're in a gym and the bench press is taken, you will be able to tap on the Swap button and see a pop up where you can swap out either the equipment (the bench press) for something comparable like dumbbells + bench, or an entirely different exercise that still targets the chest like cable chest flyesThese exercises will also be ranked from most comparable to least, and you will have all the freedom to swap out to any you like.Same for if you have sore glutes and don't want to do RDLs, just pull up the swap feature and swap the RDLs out for Hip Thrusts, Hip Extensions, etc.
