Progressive overload, actually tracked.

Kalibra logs every set, tracks all 16 muscle groups against their weekly target, and tells you exactly when you're ready to add weight — not just when it feels right.

Built around one idea: do a little more than last time.

Kalibra isn't a generic logbook — every screen exists to answer one question: are you actually progressing?

16 muscles, one map

A radar chart shows exactly which muscle groups are under, on target, or in your focus zone for the week — not just total volume.

Told when to add weight

Clear a lift for two sessions in a row and Kalibra flags it: time to add +2.5kg. No guessing.

A program in six questions

Days per week, your split, equipment, session length — answer six questions and get a full training program instantly.

PRs, rest timers, and swaps

Every set that beats your logged best gets flagged automatically. Built-in rest timers and one-tap exercise swaps keep sessions moving.

One plan. Everything included.

How payment works

Kalibra is billed through Duitku — pay by QRIS, GoPay, OVO, DANA, bank transfer, or card. There's no silent auto-charge: a few days before your plan is up, you'll get a reminder inside the app with a one-tap link to renew — monthly or annually, whichever you chose.
