ApexCore

ApexCore is a strength training tracker for athletes who already know what they're doing. You log your sets. ApexCore tracks your performance against your history and tells you exactly what to lift next session. Weight goes up when you've earned it. It holds when you haven't. No opinions, no motivational content, no AI generating advice it can't back up. The progression engine runs on deterministic logic: coded rules applied to your actual session data. Hit the top of your rep range with something left in the tank, your prescribed weight increases next session. Fall short, it holds. Plateau on an exercise for four sessions, ApexCore flags it and gives you three options. Performance trending down across multiple exercises over two weeks, it suggests a deload. Every decision traces back to a specific rule and a specific data condition. Nothing is generated. Nothing is guessed. Constraint routing works the same way. Flag an injury during onboarding and every exercise that aggravates it disappears from your program automatically. Mid-session, flag pain on a set and ApexCore offers a substitution on the spot. The rest timer runs in-workout. Session history and progress charts are there when you want them. The app gets out of the way while you train. 14-day free trial. $4.99 per month after that...less than a dollar a week. Or $49.99 per year if you're in it for the long run.
