Adensa reads your last session and prescribes today’s weight and reps, adjusted for how you actually feel.

Made by someone who needed it too

Hi, I’m Rapha.

I’m a Brazilian product manager, computer engineering student and an indie Apple developer. The Keystroke Company is the name on everything I make.

I had classes, work, deadlines and personal plans, and every tool I tried made it all feel more scattered. Neither one connected tasks and calendar in an efficient and simple way.

So I started building an app that slowly grew into Flick. Adensa brings the same idea to the gym: it tells you what to lift next, so you can stop guessing and keep getting stronger.

A few things stay the same in every app:

— Your data is yours. Data is always end-to-end encrypted, and I don’t sell (or even see) any of it.

— An app should make your day lighter, not fill it up.

— Making things today should care about tomorrow too. Flick gives 5% of eligible revenue to Trees for the Future.

None of this happened alone. A huge thank you to all of my friends, who were there from the start, and to everyone who tested an early build, reported a bug or left a review.
