About Anthony Calise

I'm Anthony Calise, an independent iOS developer based in the United States. I build small, focused apps with no accounts, no ads, and no dark patterns — and I write the deep-dive blogs that pair with each one.

What I make

Each of my apps started with a personal frustration: a tracker I wanted that didn't exist, or a tool I wished worked differently than what was on the App Store. I keep them small on purpose. One job, done well, free where possible, paid only when there's a real ongoing cost.

FiberUp

Free fiber tracker for iPhone. USDA database, barcode scanner, weekly plant count.

T-Score

Natural testosterone habit scorer. Tracks the 5 evidence-backed levers.

Word Walk

Daily word ladder puzzles. Hand-crafted, no ads, played offline.

Introvert: Daily Courage

One small social challenge a day. Forgiving streaks, 580+ challenges.

How I research and write

Most of my blog posts cover health and behavior topics where bad information is the default. To keep mine useful:

Primary sources first. Where I cite a study, I link to the actual paper (PubMed, journal site, or institutional publisher). I read the abstract, methods, and results — not just headlines summarizing them.
Effect sizes, not just p-values. A "statistically significant" 2% testosterone bump is not the same as a 25% bump. I report the magnitude.
Distinguish deficiency-correction from boosting. Many supplements only help in deficient people. I make this distinction explicit on every supplement post.
Update when I'm wrong. If a study is retracted, replicated poorly, or superseded by better data, I update the post. The "dateModified" line on each article reflects real edits.
No affiliate links in research articles. The blog posts on this site don't have affiliate links to supplements or products. (App Store links to my own apps are obviously not affiliate revenue — Apple takes a cut, and they support me building more.)

Where my expertise comes from

I am not a registered dietitian or medical doctor. My background is software engineering. The expertise I bring to the writing is:

Reading research as a daily habit. Building FiberUp meant reading hundreds of papers on dietary fiber, gut microbiome, and food composition. Building T-Score meant the same for testosterone, sleep, training, and supplementation literature.
First-person experimentation. I track everything in my own apps. Where I write about something (tracking 30g of fiber per day, optimizing sleep for testosterone, daily word ladders for cognitive maintenance, daily comfort-zone challenges as an introvert), I've actually done it.
Software engineer's instinct for "what does this number actually mean?" I notice when articles confuse correlation with causation, conflate units (ng/dL vs ng/mL vs nmol/L), or extrapolate from one study to whole-population claims. I try not to do that.

For anything medical — symptoms, lab results, supplement decisions, training programs — please consult a qualified clinician. My posts are educational, not medical advice.

How to get in touch

Email is the best way to reach me. For app-specific feedback, every app has in-app support links. For general inquiries (corrections, questions, partnerships), find me through the support page at acalise.com/support.
