One app instead of three.
A workout app plus a food app runs about R380 ($23) a month, and neither tracks a cycle or reads your bloods. MyoStats does all of it for R39 (≈ $2.37) a month, or R26 (≈ $1.59) a month billed yearly: cheaper than any of them.

Questions
What is MyoStats?
A logbook for serious lifters and enhanced athletes: plan cycles and see estimated blood levels, read blood work against reference ranges, log workouts and food against your targets, and get coaching from an AI coach or a real one.
Is MyoStats free?
Yes. The free plan covers workout and food tracking, one active cycle, five blood work panels and every calculator. Pro is R39 a month or R315 a year (R26 a month) and unlocks unlimited cycles and panels plus connecting your own AI.
Does MyoStats tell me what to take?
No. MyoStats records what you run and estimates blood levels from published half-lives. It never recommends, prescribes or doses substances. Talk to a doctor before you act on anything, especially blood results.
How are estimated blood levels worked out?
From each compound’s published half-life, your dose and how often you take it, using a simple one-compartment model. They are estimates to plan and compare cycles, not lab results.
Is my data private?
Your data is encrypted in transit and at rest, never sold and never used for ads. We follow South Africa’s POPIA: you choose what a coach sees, and you can export or delete everything at any time.
What is the AI coach?
Five AI coaches, each with its own personality and strength: powerlifting, bodybuilding, Olympic lifting, HYROX and Pilates. Hire one or several at R199 a month each. Each one reads your training and food, logs things for you and tells you what to do next.
Can I bring my history from Hevy or Strong?
Yes. Export your workouts as a CSV from Hevy or Strong and import it under Workouts. Your sessions, dates and records come with you, and exercise names are matched to the MyoStats library. You can also paste any program, from a PDF, spreadsheet or your coach, and it becomes routines in seconds.
Does it work in the gym without signal?
Yes. Install MyoStats to your home screen and it works offline; everything syncs when you are back online.
Can my coach use MyoStats with me?
Yes. Coaches invite you by link, you choose what to share, and they can log for you and set your targets and training schedule. Coaches on a paid plan give their athletes Pro for free.
