Blocksmith vs RoxHype
Where we agree
Blocksmith and RoxHype are the two products in this category built on the same conviction: a HYROX plan should be yours— built from your race date, personalised to you, and adjustable when life interferes. Neither of us thinks a template with your name on it is personalisation. If you've already decided you want personalised, race-date programming, you're choosing between us (and Formd) — and either of us will serve you better than a plan written for everyone.
What RoxHype does well
RoxHype's strength is flexibility. Don't like a session? Regenerate it or swap it, freely — it's the most frictionless “change my workout” experience in the category. It's mobile-first, the personalisation is real, and it's built by a solo developer who ships fast and clearly knows the sport. At $19.99/month it undercuts every champion program on the market.
The difference shows up after day one
On day one, both products hand you a personalised, race-date block, and from the outside they can look like the same category. The gap is everything that happens after — the eight to twelve weeks where a plan either behaves like a document or behaves like a coach.
Your next block starts from what you actually did.Log your training and Blocksmith remembers it — not as a stats page, but as programming. Loads progress from what you lifted, not what week it is. Weak stations you didn't fix carry into the next block's priorities. Sessions you consistently skipped tell the next block something about your real week. When block one ends, block two isn't a fresh questionnaire — it's a continuation. As far as we can verify, no other product in this category, AI apps included, has any version of this. Generating a plan is the easy half of coaching. Remembering the athlete is the half that makes block three better than block one.
Pushing back is a conversation, not a re-roll.RoxHype's regenerate is genuinely the smoothest editing in the category — but a re-roll swaps one plausible session for another. Blocksmith's refinement chat works like a coach across the table: tell it your knee's flared up, or that Thursdays just got taken by work, and it proposes a change to the block — you see exactly what changed, session by session, before you accept it. And the change has to obey the same recovery and phasing rules as the original program. One model gives you freedom; the other gives you “yes — but not like that.” The second one is what you're paying a coach for.
And underneath it, an engine — not a paraphrased prompt. Your paces are computed in code from your zones, phase rules are enforced, and a week that breaks recovery logic gets rejected before you ever see it. The language model never freelances your training. That's the short version; the free first block is the long version.
Honest comparison
| Feature | RoxHype | Blocksmith |
|---|---|---|
| Model | AI app | Coaching intelligence |
| Price | $19.99/mo | $9.99/mo · $79.99/yr |
| Personalised, race-date plan | Yes | Yes |
| Changing a session | Regenerate/swap freely — best in category | Coach-style refinement: proposed changes, shown as a diff, rules enforced |
| Remembers your training across blocks | No | Yes — next block starts from your logs |
| Coaching engine underneath | Unverified | Yes — computed paces, enforced phases, validated weeks |
| Platform | Mobile-first | Web app; mobile on the roadmap |
| Free trial | — | First block free, no account required |
“Unverified” means exactly that — not “doesn't have it.” We can't inspect RoxHype's engine, and you can't fully inspect ours from a comparison table either. That's why the first block is free: three minutes from intake to a written block, and the programming makes its own argument.

Who should choose which
Choose RoxHype if:you want maximum session-level freedom on your phone — regenerate anything, swap anything, no friction — and you're comfortable being the quality check on what comes back.
Choose Blocksmith if: you want a plan that behaves like a coach across the whole season — changes negotiated and shown before they land, and a next block that knows what you did in this one. $9.99/month, half RoxHype's price; less than one session with a HYROX coach.
FAQ
Is RoxHype good?
By reputation, yes — real personalisation, race-date periodisation, and the most flexible session editing in the category. This page's argument isn't that RoxHype is bad; it's that AI training apps separate after day one, on what changes mid-block and what carries between blocks.
What's the actual difference between Blocksmith and RoxHype?
Both build personalised race-date plans. Blocksmith's differences: refinement is a negotiated, rule-checked change you review as a diff (not a re-roll), and your logged training carries into the next block — loads, weak stations, everything. RoxHype's verifiable edge: friction-free regeneration and a mobile-first product.
Why is Blocksmith cheaper?
$9.99/monthvs $19.99/month. We price against the coaching market (“less than one session with a HYROX coach”), and the annual plan ($79.99) is the quiet discount.
Can I try both?
Yes, and you probably should. Blocksmith's first block is free with no account; generate it, then compare the actual sessions side by side. The programming should win the argument, not the comparison page.
