In analyzing people's percent change in total volume lifted over 60 days on FitnessAI vs users on Lift Log (a basic weightlifting journal app)
After collecting an insane amount of data with my app Lift Log, I decided to design an algorithm that optimizes for accelerated muscle growth over a short period of time.
It currently outperform human trainers by 1-2x in the first 60 days of training, using a very simple algorithm. The opportunity to change how people, athletes, and soldiers train is huge.
We're cashflow positive, raised a small seed, and are hiring data scientists & engineers in NYC to hack the human body for efficiency.
Hope to answer any questions you may have!
- Lift Log is a weightlifting journal that doesn't have any cloud functionality. It's been free for years, and I recently paywalled it at 7.99/mo or 59.99/yr (for all new and existing users). I received an incredible amount of backlash, but in the end it was worth it.
- FitnessAI uses all the data that Lift Log users generate to power an AI weightlifting coach. I charge 9.99/mo or 59.99/yr for that one with little pushback from users.
At the end of the day, you are affording your continued time and effort to maintaining your app, which is why I think a subscription model is fair.
Its not like we're writing books where all the user gets is v1.
They get v1-Infinity.
Its very easy to undervalue your work, don't!
And remember, you can always give anyone who asks free access, since you have unlimited supply :) Thats what I do for Lift Log.
Feel free to PM me if you want to talk more!

The animations are great – but I think you should speed em up a bit. The long ease-out period makes it tough to concentrate on small changes. Will most definitely use this!
My only question is how a highly productive individual at a top bank or startup justifies taking the time out of their day to speak to a newbie. I know they get paid, but I would imagine it's peanuts compared to their 6 figure salaries. What is their main motivation in scheduling calls?
There are a few points I'd like to address:
> Only by carefully restricting the supply has De Beers kept the price of a diamond high.
This was the case a long time ago but not anymore. De beers seems to only have a 37% market share - not enough to control the market. [O]
> Diamonds, however, are not an investment. The market for them is neither liquid nor are they fungible.
Not entirely true. Diamond prices fluctuate and have appreciated in value over time, you just have to be savvy about it like any other investment. It's unfortunate that the markup on lower quality diamonds is so high but its largely due to a lack of knowledge on the consumer side. AKA do your homework and buy/sell from a wholesaler like abemor.com (wink, wink)
> You might want one because it looks pretty or its status symbol to have a “massive rock”, but not because it will store value or appreciate in value.
You can say the same thing about art. Diamonds are collectors items.

Its curious that both of us worked on the apps receiving the phantom update
It highlights the same exact security issue. The solution is simple: only ask for passwords in the SETTINGS app. Have the alert route users there.
