Why Tonic

Most weight apps were built before GLP-1 existed.

They count calories, throw confetti, and miss the point. Tonic treats your dose, your symptoms, your meals, and your weight as one connected story — because that’s how your body works.

× Calorie counters
  • Throws confetti when you skip a meal you didn’t want.
  • No idea your appetite just dropped 70%.
  • Treats nausea as a willpower issue.
  • Pings you to log a snack while you’re sick.
Tonic
  • Connects your dose day to your appetite, weight, and mood.
  • Logs side effects in a tap and tracks the patterns.
  • Quiet on hard days. Loud on real wins.
  • Designed with people actually on GLP-1.
Live guilt-free

Meet you on the hard days.

Side effects are part of the road. Tonic acknowledges the rough days, celebrates the ones worth celebrating, and never guilts you for missing a log.
