Set the goal.
WhispCal steers.
Autopilot watches your weight trend and moves your calorie target for you — every few days, in plain language, from rules you can actually see. Not a black box. Not another spreadsheet.
Free on iOS & Android
Phase one is free, forever.
A coach that runs on rules, not vibes.
Most apps either freeze your target forever or hide the logic inside a model you can't question. Autopilot does neither: it adjusts as your body changes, and it shows its work every step.
01
Rule-based
Every nudge traces back to a simple, visible rule. Same inputs, same output — no model drift, no guessing.
02
Transparent
You see the comparison, the recommendation, and the reasoning. Confirm it, postpone it, or overrule it.
03
Offline-first
It runs entirely on your phone. No account, no server round-trip, no waiting on a connection.
Two signals have to agree before anything moves.
Weight is noisy — water, salt, sleep, your cycle. So Autopilot waits for a comparison window (five days by default, adjustable from three to fifteen) and only acts when both signals point the same way.
Both agree →
One clean step. When they disagree, it waits — so a noisy week never triggers a false move.
±200 kcal
One system. Every goal.
Autopilot guides you through five phases. Start by finding your true maintenance — free, forever — then cut, reverse, bulk, or reset whenever your goal changes.
Find Peak Maintenance
FreeDiscovers the highest intake where your weight holds steady — your real maintenance, measured from your data, not guessed by a formula.
Cut
PremiumGuided fat loss from peak maintenance down. Holds while you're losing, eases off when you stall, and raises calories with Recovery Mode if your energy dips.
Reverse Diet
PremiumSlowly rebuilds calories after a cut, finding a new — often higher — maintenance without piling the fat back on.
Bulk
PremiumA controlled surplus from peak maintenance up: enough to grow, measured enough to stay lean.
Reset
PremiumA combined cut-and-reverse cycle to shed an off-season and rediscover your ideal composition.
A 30-second check-in. That's the whole job.
When the window closes, the Brief shows your phase, your target, the weight comparison, and the recommendation on one screen. Autopilot proposes — you decide.
Confirm
Accept the new target and keep rolling.
Postpone
Not ready? Slide the window forward a few days.
End phase
Goal changed? Switch phases anytime.

Autopilot, answered.
Is Autopilot free?
Phase 1 — Find Peak Maintenance — is completely free, with the full dual-signal engine. Phases 2 to 5 (Cut, Reverse Diet, Bulk, Reset) are part of WhispCal Premium at $4.99/month or $39.99/year.
How often does it change my calories?
Only when your comparison window closes (five days by default, adjustable from three to fifteen) and both signals agree. Each move is a single ±200 kcal step — never a partial or runaway adjustment.
Why rules instead of AI?
Because you can see exactly why every recommendation happened, the same inputs always give the same output, and it runs entirely offline on your phone. Transparent rules earn trust that an opaque model can't.
What is the dual-signal check?
Autopilot compares the trend line across your weigh-ins and your actual weight change since the window started. Both must agree before it nudges — so a noisy week of travel, salt, or poor sleep won't trigger a false adjustment.
What is Peak Maintenance?
The highest calorie intake at which your weight stays stable — measured from your real data, not estimated by a TDEE formula. It's the anchor every other phase builds from, and it can rise after a successful reverse diet.
Does it work without internet?
Yes. Autopilot runs on-device. No account or connection is needed for it to compare your weight and recommend your next step.
