UPDATE Dec 16, 2014: 1 WEEK ON KICKSTARTER! Thank you to our 108 Backers for helping us cross $10,500 mark!
We are announcing some updates on rewards:
- We will be giving out a Dri-Fit "STRIDALYZER" T-Shirt to ALL current and future backers on the $26 (Marathon Backer) level!
- We received your feedback that there is a big gap between $26 and the $90 levels. So we added a $50 (Triathlon Backer) level!
- We added a "Running Coach" Backer level at $1000 level - for all trainers and coaches out there who have expressed interest in using our product in their running classes.
- We will give out an extra T-Shirt for every backer you recommend that contributes on the $90 or higher level! Please ask the backer you recommend to put "Recommender: <Your Name>" in the comments when backing!
The key to good running is in the fundamentals – your Running Form. Rather than focus solely on reporting metrics, Stridalyzer helps you understand, and improve, your form through an actionable, guidance-based approach and technology. While there are a lot of debate on the best way to run, there are two aspects of running that everyone can agree on: the “Right” way to run is unique to every person’s body, and that preventing injuries and increasing performance comes from the “right” form.
Stridalyzer helps you with determining YOUR right form, and helps you achieve that.
"Then I came across the Stridalyzer. A wearable for runners, it analyzes the stride and gait and, among other things, can predict if one is heading for an injury. Even a non-runner like me could see the value of that kind of information to a runner or a sportsperson." -Ramya Venugopalan, YourStory
Stridalyzer uses a pair of insoles with a novel, patent-pending technology with multiple sensors integrated in them, to detect how your foot lands, rolls and pushes off the ground. All you need to do is put these insoles in your shoes, turn the app on, and start running; Stridalyzer automatically understands that you are moving, and will start collecting data about your run.
Alerts and advice – when you need them
We have designed our solution to continue to monitor your run, and interrupt you only when it needs to “alert” you with some important information or quick guidance. For example, if you start persistently overpronating, or if your footstrike pattern changes, you will get a visual as well as an audio alert - this way you can keep your eyes on the trail and still get the information or advice that's relevant for you - WHEN it becomes relevant!
Foot and knee stress monitoring and real-time review
One in four runners will have some kind of knee injury in any given year. Of all running injuries, about 42% are knee injuries. So we made it our top priority. Stridalyzer can estimate the various stresses acting on your knee and provide you with alerts, guidance and detailed data for your review, that can help you understand when and how you are overstressing your knees, and help prevent the all-too-common “runner’s knee”.
Of course, Stridalyzer provides the real-time foot stress map as well. You can replay these maps for your previous runs as well - An awesome tool to help you find your next pair of shoes, or to take to your running coach!
Performance-Train like a pro!
If you are trying to buildup your pace or find the optimal rhythm for your next marathon, Stridalyzer helps you monitor and track the three fundamental performance parameters: Stride Rate, Stride Length and the most elusive – Ground Contact Time. Using our patent-pending technology, we can measure ground contact time extremely accurately!
Intuitive reports and guidance
Like many fitness tracking device, we measure various types of data. However, unlike those trackers, we have worked with fitness trainers to come up with intuitive, easy-to-understand metrics to help you measure your “overall” run performance using two fundamental metrics: PerfScore, which is your overall run performance score (aggregating distance, pace, incline, stride length & rate, calories burnt, etc), to reflect the overall “effort” made by you.
"So far most footwear wearables have focussed on mapping the runner’s route, distance, pace and time, and gamified with social shares and audio cues; few have tried to explore the runner’s technique and use data to help improve their run." -Vinay Dora, e27.co
We also defined a measure called “FormScore” – (aggregating the stresses on your feet and knees, overpronations/underpronations, etc) to give you an idea of your overall “form” during the run.
In addition, you can get an idea of how you foot-strike and foot-roll - as an overall run-summary distribution, or as your strike type over your run duration. This can help you understand what kind of strike pattern and roll pattern you have when you hit the "fatigue wall", and can help you create the right strategy for your next 10K or the next Ultramarathon!
Who are we?
We, ReTiSense, really like running. And technology. Anshuman and Ryan have been long-distance runners for several years, and have had their share of running injuries and problems. Additionally, Ryan is an expert in the Software Architecture, UI Design and mobile app development, and a certified Agile Development trainer. Anshuman is an expert on Analytics who enjoys looking for patterns in data and in life. Shuvadeep is our resident expert at sensor and circuit technology. Gaurav, Rakesh and Jayaraj are crazy-energetic guys working on the web technologies. Neeti is our Supply Chain expert who is fanatical about sustainability, so she is constantly beating us up to ensure we use eco-friendly materials, and save even microwatts of battery power (yes, we told her it’s rechargeable, but even then).
We have been blessed to have the advice and consultation of several sports trainers, consultants and physicians – some paid, some who just really like what we are trying to do. And finally the runner community in Bangalore, San Francisco and Austin for their help, advice, and early trials.
"ReTiSense could be about to make a huge breakthrough for runners." -James Stables, WAREABLE.com
Where are we in our development?
We have been iterating and improving our product from one prototype to the next using the AGILE methodology: Prototype -> experiment -> get feedback -> make improvements->repeat. This has worked very well, for hardware as well as software.
We are at our 3rd revision of the prototype, and we are starting our early user trials in mid December with about 25 pairs of insoles. We are building these manually, and one big learning we have had is it's really difficult getting a pair of insoles integrated identically when doing the integration manually!
Below is the High-Level Timeline for our product. We plan to complete our App work by April, and the manufactured product should start shipping out in April 2015!
We have logged hundreds of runs in our internal testing and limited-user trials. We aim to log about 1000 hours of runs in each limited-user testing phase, before we green-light our volume production. And that's when we need the BIG BUCKS, and we need YOUR HELP to get there.
Our Manufacturing Plans
We have been working closely with our component suppliers (our patent-pending technology requires very specific components), electronic contract manufacturers, insole manufacturers and final product aggregators. We have finalized our contract manufacturer and our insole supplier, and currently working together with them to define the best process of integrating the circuitry into the insole.
Our trial manufacturing run (planned for early January) will enable us to further improve the manufacturing and integration process, and also provide us with the “almost final” prototypes that we can give to our testers for their feedback.
At the end of January, we plan to provide the go-ahead for first-lot volume manufacturing. This is where your help becomes critical! We would need to get AT LEAST 500 pairs manufactured and shipped for distribution, and we need a minimum of $25,000 to be able to accomplish that.
While our minimum requirement to get Stridalyzer, in its current form, to you is $25,000, we have a lot of plans and hopes for Stridalyzer. In addition, many of our testers, trainers and coaches have requested for certain features, which would be awesome to add, if we can afford to implement them. So, we are putting the top few as stretch goals. Please help us meet those stretch goals, and make Stridalyzer even more AWESOME - at the same price!
Think for a second:
- Every year, about 65%-70% of all runners will get an injury!
- Of those, about 40% will suffer KNEE injuries!
- 90% of Marathon trainers are prone to injuries!
Even if you are not a runner, you definitely have friends, relatives, family who are. Help us bring a product to them, that can make their life a lot more pain-free!
What YOU get for helping us
First and foremost, you get good karma for helping an awesome product come forth in the world! :-)
In addition, you get a whole bunch of tangible and intangible gifts. For our backers, we are providing Stridalyzer as a gift for contributions starting at $75 - almost half the amount at which we plan to retail Stridalyzer! We are also giving away complimentary ExpertConnect service to contributions starting at $130 - a service that can connect you to expert runners, trainers, coaches and have them give you advice based on your run data available on Stridalyzer web portal. ExpertConnect is planned to launch around 2-3 months after the product launch once we have gone through the legalities and regulatory processes of being able to provide such a service.
Here is the summary of all rewards:
THANK YOU FOR BACKING US!
UPDATE: Dear Backers & Supporters - KICKSTARTER.com demanded that we add a video of the prototype WORKING, on Dec. 16, 2014. Here's the video. Please pardon the poor quality of the video, as we were not able to get a professional shoot done for this purpose, given that we are extremely busy with our product development as well as running the campaign.
Risks and challenges
While we have done our due-diligence for all aspects of the product, the following are still real risks with the project:
1. Ability of the Contract manufacturer to deliver the circuits on time - either due to the issue with the contract manufacturing process, or delay with component suppliers.
2. Ability of the insole manufacturer to integrate the circuitry in the insole - while the insole vendor has demonstrated the circuitry integration on a sample of insoles, insertion during volume manufacturing still needs to be demonstrated.
3. Changes in support parameters and metrics for BlueTooth LE or GPS infrastructure in iOS and Android could cause us to redo some of the work and can push out the time of release of the App.Learn about accountability on Kickstarter
The insoles we use are similar size and materials as the insoles that are present in the high-end running shoes. Our insoles are about 5mm thick, with a high side-wall near the arch, which houses the circuit. We have tested with various shoes – these insoles should feel just like your current regular insoles, and should not affect how you run at all.
You should be able to use this insole on top of the other insole. We would recommend that you consult with your physician to be sure.
We will be building a few common sizes to start with, since our planned initial lot is very small. However, it will be possible to trim the insole down upto 1 size, using your scissors, to fit snugly into your insole. Your Stridalyzer will come with directions on how to do that.
Yes. Both insoles collect and send data independently. We do not believe people use their legs identically when they run; in fact, most people have legs and feet that are different sizes. In addition, if you have had an injury or strain on one side, ever, your body unconsciously compensates for that. So it is vital to monitor both feet and knees. Hence, we do not plan to sell a single insole.
If, however, you are one of the superheroes that have somehow lost one leg and still run, please do write to us on the email address on our website. We have budgeted a few Stridalyzers every month for inspirational people with special abilities, and we would be honored to provide you with a complimentary Stridalyzer insole if we can.
We are currently supporting iOS – any iPhone starting from iPhone 4s. We will be supporting Android by the time we launch in April. We do not have plans to support other platforms beyond that in the near term. If we exceed Stretch Goal #1 and #2, we will be able to fund development and testing for Apple Watch and Garmin respectively.
Stridalyzer cannot work without a smartphone. While it’s possible for Stridalyer to collect and store data for a run in the insole, the fact that the user cannot get any real-time feedback or advice, violates the fundamental tenets of our philosophy to provide actionable guidance. When connected to a Smartphone, Stridalyzer can provide real-time alerts, guidance, etc that makes the running experience a lot more satisfying.
Our tests have shown that Stridalyzer’s battery would last about 8-10 hours of running on a single charge. That should cover about a week for most runners.
The insoles will come with a USB charging cord, and you can connect it to any USB charging wall-point. Each insole battery should get fully charged in about 15 minutes.
We get this question a lot. We use the data collected on the feet, to calculate the amount of stress being exerted on the knees. We build a computer model of the legs on our cloud server and customize them for each user based on the information provided by them. Using the data collected by your insole, we build the model to understand exactly how you moved your feet, and also how your knee was positioned during the various stages of running stance, and calculate how much stress was transferred to your knee in the various stances. Again, this is possible only because we know how each part of your foot moved when you made contact with ground.
ExpertConnect is our premium service, planned to be released a few months after the product launch, to enable runners to get much more individualized and directed advice from running experts, coaches, or trainers. These experts and trainers will get access to the specific data you want to share with them, and will provide guidance on specific aspects of your run.
We at ReTiSense are passionate about running. We believe running eventually defines a person, and their value-system. For our versioning system, we decided to use names that would honour the places and people that have contributed immensely to the sport of running in particular, and to the world in general, and the first such place we wanted to honour was Marathon – where the legend has it that Pheidippedes ran about 150 miles to Sparta first, to ask for help, then back, then fought the Persian army, and finally ran about 26 miles to Athens to deliver the news of victory, and died. His contributions helped that significant battle, and had a major influence in the history of the world.
Stridalyzer takes privacy and security of your data very seriously! The data on your phone complies with all privacy and security requirements from Apple (iOS) or Google (Android). All transmissions from the phone to the cloud uses industry-standard encryption, with keys that are unique to each app. The data on the cloud are encrypted, and only you have access to the data that is stored for your account.
These insoles are meant to last about one year. As you may have noticed with your running shoes, the bottom soles are the ones that run out. You can simply move the insole to your new running shoes.
