Every app in this category calls itself free. Some mean a hard cap, some mean a three-day trial, some mean ads between you and your result. Here are seven options with the fine print stated up front — including the two that stay free permanently.
The GainFrame Roadmap for the Next 90 Days
I want to reduce paid churn by 30–50% and improve paid retention by about 25%. I have a product direction for getting there, but several of the ideas still need to earn their way into the app.

Four calculators, four different numbers, and no way to tell which one is closest. Here's the honest error range behind each method, why they disagree, and the reframe that makes body fat tracking useful anyway.

You can get a physique rating from a gym scale, an app, a judge, or a stranger on the internet — and all four numbers mean different things. Here's what each scale is grading, and which parts of yours are worth reading.

You can't see your own physique clearly - nobody can. Here are the four ways to get an outside read on it, what each one actually tells you, and how to tell useful feedback from noise.

Your muscles have a monthly speed limit and your fork doesn't. The honest rate math for how fast a bulk should move, a worked example of the check, the four warning signs the surplus is going to fat, and the correction that isn't a panic cut.

The average American man measures somewhere around 23-28% body fat - at the top of the band category charts label average, and often past the line they flag as elevated. Here are the men-specific ranges, why male numbers run lower than female ones by design, and what 18%, 23%, and 28% actually look like on the same body.
Average Hand Size: Length, Span & What It Means for Grip
The average male hand is commonly cited around 7.4 inches long with an 8.5-inch span — but most people who look it up have measured the wrong thing, or measured nothing and compared against a basketball player. How to measure length and span correctly, what hand size tracks, and what it honestly doesn't.

The App Store screenshots are the wall every solo dev hits — you can build the product but lose a weekend fighting device frames. Here are the five best ways to make them, ranked by how little time they cost.
Body Recomposition Over 40: What Changes and What Doesn't
The doom content about training after 40 is mostly wrong. Muscle still responds, fat still comes off — what changes is recovery, protein math, and how long you have to wait to see it. Here's the honest version.
Chest-to-Waist Ratio: The Other V-Taper Number
The V-taper has two measurements, and most people only know one. The commonly cited ideal chest-to-waist ratio sits around 1.33–1.4 — a different number than the golden-ratio shoulder figure, taped at a different place. Here's the worked table, the protocol, and which lever to pull first.

MacroFactor Review (2026): The Nutrition App We Keep Recommending
We keep pointing readers at MacroFactor in our cutting and GLP-1 guides, so it's time to explain why. The short version: it's the only mainstream tracker whose calorie targets are built from your data instead of a formula's guess.
I Hit $1,000 MRR and Forgot to Celebrate. Starting a Second App at Zero Fixed That.
GainFrame crossed $1,061 MRR and now adds close to 500 new users a week. I barely noticed either — I'd already moved the goalpost. Then I started SEO Receipts from zero, and grinding for the first users reminded me what all of this used to be worth.

Skinny Fat for Women: Why It Happens & the Way Out

Gym culture says 225 is a warm-up. Population data says most men can't bench their bodyweight on day one. Strength standards are the map between those two realities - here's how to read them without letting them read you.
