Training log
Every set, rep, and load, from 873 exercises.
Nutrition log
Search 8,000+ foods from USDA data. Portions, not guesses.
Macro targets
Calculated from your training, not a generic formula.
Today's readiness score
Sleep, soreness, energy, and yesterday's food, in one number that tells you what to do today.
Readiness history
Every score you've logged, so you can see whether the number is trending up or you've been grinding into a hole.
Custom exercises
Add anything the library doesn't have. Your gym's machines, your variations, your names for them.
Delta chat
An AI coach that reads your sets, your food log, and this morning's check-in before it answers. It doesn't ask what you did — it already knows.
Delta insight cards
Delta flags what changed without being asked. Protein short three days running, readiness sliding, a lift that’s stalled.
Data export
Every log you've written, in a file you own. No lock-in.
Free trial
14 days if you join the launch list before release.
What happens when the trial ends?
The subscription starts automatically and your Apple ID is charged $19.99, unless you cancel at least 24 hours before the trial ends. It then renews monthly until you cancel.
Can I cancel anytime?
Yes — from your Apple ID account settings, at any point. Deleting the app does not cancel the subscription; it has to be cancelled through Apple.
What do I lose if I downgrade to Core?
Delta. Everything you logged stays — training history, nutrition history and past readiness scores are all still there, and the log keeps working.
