EntrenAI or Repz: a HYROX-only app or one plan for everything you train?
Repz is built only for HYROX and announces itself as the competition's official online training partner. EntrenAI has HYROX plans inside an app with 12 sports, where the HYROX plan is coordinated with your strength and running. If HYROX is all you do, Repz is hard to ignore; if not, the comparison changes.
Updated
Repz is a training app built only for HYROX. According to its August 2026 announcement, it is the competition's official online training partner. It builds the plan around your weak points, the equipment you have and your target time, covers the running and the eight stations, suggests exercise alternatives by equipment (full gym, home gym, hotel dumbbells), periodizes to race date and recalculates every week based on the sessions you complete or miss. It costs $19.99 a month or $119.99 a year, with a 7-day trial, and is rolling out the app in several languages.
EntrenAI is an iOS and Android app that generates a periodized plan for 12 sports, HYROX included, with plans for beginner, intermediate, advanced, doubles and simulations. The HYROX plan shares the week with your strength and running, swaps exercises to your equipment and calculates an estimated total race time from your training. Every morning a sleep, stress and fatigue check-in produces a Readiness Score that raises or lowers the day's load. The plan is calculated by a rules engine, not a language model, and the methodology is published.
The question is how much of your week is HYROX. If nearly all of it, an app made only for that, with the organization's backing, is a very strong option. If HYROX lives alongside your lifting, running or cycling, EntrenAI is built for that.

Who should pick which app?
EntrenAI is for you if HYROX is one of several sports you do and you want one plan to coordinate them, if you want to pay less, or if you want to start free: free workout logging costs nothing, and the plan has a 7-day trial.
Repz is for you if your training is HYROX from start to finish, if you value the competition's official backing and an app that does nothing else, and you do not mind paying noticeably more.
Use both only if you want to compare HYROX plans during each one's trial. Holding both subscriptions at once rarely makes sense, because each wants to organize your week.
Frequently asked questions
Yes, if HYROX is not the only thing you do. EntrenAI has HYROX plans by level, with doubles and simulations, and coordinates them with your strength and running inside one plan. Repz is made only for HYROX and has the competition's official backing, so for someone preparing only HYROX it is a serious rival.
EntrenAI. Repz costs $19.99 a month or $119.99 a year, with a 7-day trial, according to its announcement and the store listings. EntrenAI costs €7.99/month or €23.99/year, with a 7-day trial, and free workout logging costs nothing. Prices change, so check the current one before deciding.
Yes, according to its August 2026 announcement, Repz is HYROX's official online training partner. EntrenAI is an independent app with no official relationship with the organization. If that backing matters to you, that counts for Repz.
That is where EntrenAI differs. A HYROX-only app does not prepare the rest. EntrenAI coordinates HYROX with your strength, running or cycling in the same week, so the leg session does not ruin the long run.
In different ways. Repz recalculates every week from the sessions you complete or miss. EntrenAI does that and also uses a daily sleep, stress and fatigue check-in that produces a Readiness Score, with rules that are published.
You can, but it rarely makes sense. You would pay for two subscriptions and each app wants to organize your whole week. The sensible approach is to try each during its trial and keep the one that fits.
Specialization and official backing. Repz is made only for HYROX, covers the running and stations with a plan built around your weak points, and has the competition's endorsement. EntrenAI launched in May 2026 and has no watch app of its own. Its advantage is price, the free tier to start and coordinating HYROX with everything else you train.
