Every set,
counted.

How it counts
One set. Every muscle it works.
A 2026 analysis of 67 studies tried counting the helping muscles' sets as nothing, as half and as whole. Half matched muscle growth best, so Throttr counts every set you log that way, for every muscle, all week.
1set for the muscle doing the work
½set for each muscle that helps
The app
Log the set. Snap the meal. See the week.
-
Log
Weight, reps, and the reps you had left. The rest timer starts the moment you log.
-
Food
Photograph the plate, say what you ate, scan the barcode, or search 20,442 foods offline.
-
Progress
Every muscle takes the colour of its week, so the one you keep skipping shows early.
And the rest
Everything around the set.
Plans, checked
Pick a plan or build one with the AI. Before your first set, it checks every muscle's week and every workout's length.
A coach that read your log
Ask about your training or your food. It looks up your own workouts and meals first, and shows the studies behind its answer.
Works without signal
Log sets in a basement gym. With an account, everything syncs when you are back online.

Questions
Before you start.
- Is it free?
- Logging is, for good: your training, food, plans, progress and syncing, with no card needed. The AI (meal photos, voice notes, the coach and AI plans) comes with Throttr Pro, $24.99 a year. Until Pro opens, the AI is free for every account, within a monthly limit. After that, a free account can still try it: 10 meals, 10 coach questions and 1 plan.
- Is there an app to download?
- No need. Throttr runs in the browser on any phone or computer. Add it to your Home Screen and it opens from its own icon, like any app.
- Do I need an account?
- No. Without one, what you log stays on your device. A free account keeps a copy on our server so your devices stay in step, and it turns on the AI: meal photos, voice notes, plans and the coach.
- Does it work without signal?
- Yes. Log your sets in a basement gym. With an account, everything syncs when you are back online.
- What happens to my data?
- It stays yours. No ads and no trackers, and it is never sold or used to train AI models; how the app is used is counted only in totals that do not say who you are. Download it any time; deleting your account deletes it from our server at once.
- Who is it for?
- Anyone 16 or over who lifts to build muscle. It is a training log, not medical advice: talk to a doctor before a new plan if you are injured, pregnant or unwell.
