About
Who builds this, and what actually exists.
Zealo is an iOS training, nutrition and recovery app built by one person. This page exists so you can tell what is shipping today from what is still being built, without having to guess from marketing copy.
The company
AutoClosure
The app and this site are published by AutoClosure, an independent software company founded by Manikanta Sirumalla. There is no team behind it, no investors, and no editorial staff. When this site says “we”, that is one person and the sources he cites.
The name
ZEALO is the next chapter of RepTrack Pro
ZEALO is the brand this product is being built out as. It is a rename, not a different app and not a separate company: same codebase, same developer, same App Store listing.
Being precise about that matters, because the two names are both live right now. This site is written as Zealo. The App Store listing is not renamed yet, so what you download still says RepTrack Pro.
What ships today
RepTrack Pro 2.0.2, a free workout logbook
The build currently on the App Store is RepTrack Pro 2.0.2, and it is a free workout logbook. You log sessions, sets, reps and weight, and you keep your history. That is what you get if you download it today.
The wider system this site describes, the AI program generation, the metabolic dashboard, the cycle-aware guidance, is what Zealo is being built into. It is not all in the shipping build yet, and there is no subscription to buy at the moment. If you want to know whether a specific capability is live before you download anything, ask.
The builder
Manikanta Sirumalla
Manikanta Sirumalla designs, writes and ships all of it: the iOS app, this site, and every article in the Learn library. He founded AutoClosure, builds Zealo, and is a graduate student at the University of Maryland, Baltimore County.
He is a software engineer, not a clinician. Nothing on this site is written by a physician, a dietitian, or a certified exercise physiologist, because there isn't one involved. What there is instead is a rule that every number has to name its source before it ships, and a public record of features cut when the evidence did not support them. More on him on the author page.
