fatnag

Nag until the fat folds.

Daily weigh-ins that keep the routine until the loss shows. Honest numbers. Optional Keel when you go soft.

Bluetooth scale auto-detect Apple Health 18+

Works with

  • Bluetooth scales (auto-detect)
  • Apple Health

The loop

One job. The goal you set.

Done pretending it fixes itself. Weigh, stay honest, win the week - or get offended. That is the point.

Step on. Confirm. Move on.

Step on a Bluetooth-compatible scale. fatnag auto-detects it, settles the reading, writes to Apple Health. Manual entry when the scale is elsewhere.

  • Auto-detects Bluetooth-compatible scales nearby
  • Body fat when impedance lands
  • Same-time weigh habit beats heroics

Win the week, not the hour.

Horizon arc, daily energy / protein / steps, and a today-ahead line that tells you what actually matters before Sunday.

  • Aggressive weekly catch-up when you fall behind
  • Red card when a spike looks like noise or sabotage
  • Progress charts with ideal line - no dashboard soup

Progress / charts Replace with weight history + ideal line

Keel coach

Live pressure. Weekly credits.

Keel is the only voice you talk to - blunt, local-language humour, no multi-agent dump. Free / Plus / Pro caps keep chat from becoming a coping hobby.

On-device polish when Apple Intelligence is around. Optional Grok when you consent. Never a medical device.

Lie to yourself and you get offended.
Good. That is the point.
