Most workout apps are built for the gym. AthleteCraft is built for athletes who train things the gym has no name for. If you practice stickhandling, shooting, sprints, agility or ankle mobility, you already know the problem: you can log the work, but you can't tell whether any of it is working. Every other app wants reps and weight and picks your exercises from a list that doesn't include yours. BUILD YOUR OWN EXERCISES Type your own exercise name. Whatever you actually do — "toe drags," "corner 3s," "20m sprint" — becomes a tracked exercise. No list, no substitutes, no pretending your drill is something else. CHOOSE WHAT A SET IS MADE OF Create presets with up to five inputs you choose. Shooting might be makes and misses. Sprints might be reps and time. A mobility test might be a single measurement. You decide what gets recorded, so tracking finally fits the training. SEE WHETHER IT'S ACTUALLY WORKING Pick an exercise and build a View: choose a preset, multiply or divide its inputs, then show the average, total or highest. Your progress appears as a graph across 30, 90, 180 or 360 days, split into six intervals — so you're comparing periods instead of guessing from your best day. All of that is free, permanently. ATHLETECRAFT PRO Pro adds the analysis layer on top: • Skill Map — compare six exercises against each other and find the one that's lagging • Training Statistics — personal bests per exercise, and your ten most-logged • Consistency Score — a weekly score from what you planned versus what you did • AI Trainer — a chat that can see everything you've logged and answer questions about how to train better • Games and practices — log drills, stats and notes from real competition Built by a former competitive hockey player who got tired of not knowing. — AthleteCraft Pro • $5.00 per month, or $30.00 per year • 7-day free trial. It converts to a paid subscription unless cancelled at least 24 hours before the trial ends. • Payment is charged to your Apple account at confirmation of purchase. • Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. • Manage or cancel anytime in Settings → your Apple ID → Subscriptions. • Cancelling keeps every free feature and all of your data.

CircadiaOS adjusts your bedroom temperature through the night, automatically. Your body temperature isn't constant while you sleep. It drops as you fall asleep, stays low through your deepest sleep, and rises again before you wake. A thermostat held at one number all night works against that. CircadiaOS builds a temperature curve for your night and drives your smart thermostat to follow it. Connect a wearable and the curve adapts to your own recorded nights instead of a general model. HOW IT WORKS - Connect your thermostat and your wearable - CircadiaOS builds a curve from your profile on night one - As your nights accumulate, the curve shifts to your own data - See exactly which parts come from your sleep and which are still estimates WHAT YOU SEE - Tonight's schedule, phase by phase - Why each setpoint is what it is - Your best and worst nights, side by side, and what differed Requires a compatible smart thermostat. A wearable is optional but unlocks personalization from your own sleep data. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is rating: AthleteCraft at 5.0 against CircadiaOS's 3.5. AthleteCraft also leads on ads (none vs shown) and iOS requirement (16.4 vs 18.0). CircadiaOS's advantage is update cadence (every 3 days vs every 2 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
