Fair questions, straight answers.

Flexbound is a workout notebook app for iOS. You write training and food notes in your own words; the app parses them into structured sets, meals, and bodyweight data without ever rewriting your raw entry. Deterministic, cited math handles progression, macros, and TDEE. AI only writes and explains.

Two ways. First, Flexbound starts with free text you write, not forms you fill. Second, our methodology is published as versioned rules citing peer-reviewed research, and AI is architecturally banned from producing numbers. We document every formula on the site, including its limits.

Flexbound is in development for iOS, opening on TestFlight first. Email us to join the early-access list. Android is not committed yet; tell us if you want it.

Yes. Flexbound is local-first: the notebook, parsing, and calculators run on your device with zero configured accounts. Signing in adds backup, sync, and the cloud-assisted Pro features.

Yes. You declare where you train and exactly what equipment you own: dumbbells, kettlebell, bands, a secure band anchor, a pull-up bar, a bench or box, or nothing. Plans draw only from movements your equipment can perform, session length is treated as a hard budget, and honest limitation notes appear when a pattern such as vertical pulling is not trainable with your setup.

As long as you actually have. Session length is an onboarding question, and the planner budgets each day to fit: a 30-minute plan trims accessories and shortens accessory rest while protecting the priority compounds, rather than cramming a 60-minute session into half the time.

No. Calories, macros, TDEE, estimated 1RM, volume, and progression come from versioned deterministic calculators grounded in peer-reviewed research. AI may only rephrase and explain results the math already produced. If AI prose introduces a number the calculators did not produce, the app discards the prose.

Four things: rephrase a completed weekly review, explain a completed workout plan without changing it, draft a parse for ambiguous journal lines (which you confirm), and summarize research for human methodology review. It cannot approve rules, set targets, or touch your data.

No. Your journal content is not used for third-party advertising or model training. Cloud AI features are consent-gated, and the privacy policy spells out exactly which subprocessors see what.

The notebook, forever: unlimited raw journaling, deterministic workout parsing, food notes, bodyweight tracking, and backup/restore/sync. Free history is retained for 30 days of confirmed records (with warnings and full export before any purge).

Sourced calorie and macro estimates (USDA and Open Food Facts first), adaptive TDEE, weekly reviews, workout plans, deload and pain-flag signals, saved meals, and unlimited history.

Pricing will be announced at launch. TestFlight testers hear first. The free tier is not a trial; the notebook stays free.

Yes. The full JSON export includes raw entries, confirmed structure, corrections, and history. Imports work too, including backups from before the app was renamed to Flexbound.

Yes, from inside the app: deletion removes remote data and the account, then clears the device. No email ping-pong required.

No. Flexbound provides fitness tracking and nutrition estimates, not medical advice, diagnosis, or treatment. Persistent pain, disordered-eating risk, or health conditions belong with qualified professionals. The app is built to say so rather than coach past its depth.
