Start Tracking in Under a Minute
- 01
Pick a Template or Build Your Own
Choose from ready-made templates for lifting, running, cycling, swimming, or weight tracking. Or create a custom workout with exactly the fields you need.
- 02
Log Your Session
Record sets, reps, weight, distance, duration, and RPE as you train. Everything stays on your device, encrypted before it even hits storage.
- 03
Review and Progress
See your history, spot trends, and track PRs over time. Optionally sync across devices with end-to-end encryption — nobody sees your data but you.
Built for People Who Actually Train
Everything you need to track workouts consistently — without handing your data to ad networks.
-
On-Device Encryption
Your workout data is encrypted before it's stored. Not on a server. Not after upload. Right there on your device, immediately.
-
Workout Templates
Pre-built templates for running, swimming, cycling, lifting, and weight tracking. Duplicate and tweak them to match your actual program.
-
Custom Fields
Track sets, reps, weight, distance, duration, RPE — or any combination. Your workouts aren't one-size-fits-all and your tracker shouldn't be either.
-
Works Offline
No Wi-Fi at the gym? No problem. Log everything offline and it's all there when you're back. Zero data lost.
-
No Account Required
Open the app and start tracking. Anonymous authentication means no email, no password, no sign-up form standing between you and your workout.
-
Optional E2EE Cloud Sync
Train on your phone, review on your tablet. End-to-end encrypted sync keeps your data available across devices without exposing it to anyone.
Charts and trends
Multiple chart types
Custom analysis
Built for any kind of tracking
Design your own templates or let AI do it for you.

Why people switch to Quanitya
Encrypted and on your device
Your data is encrypted and stored locally. The server can't read it — even if someone broke in, they'd get nothing usable.
No account, no email, no password
Sign up anonymously. No personal information collected. We don't know who you are and we like it that way.
Track it your way
Build custom templates with the fields you actually need — or describe what you want and let AI create it for you.
Works offline, syncs when you want
Everything works without internet. Want your data on all your devices? Optional encrypted sync keeps everything in sync — still end-to-end encrypted.
Free forever
All tracking, templates, charts, and local analysis are free with no ads. Cloud sync and advanced AI analysis are optional upgrades.
Source code you can verify
Our code is publicly available. Don't take our word for the encryption — check it yourself.
We can't see your data — even if we wanted to
Your entries are encrypted on your device. If you turn on sync, data is encrypted before it leaves your phone — the server only stores blobs it can't decrypt. We don't collect names, emails, or any personal identifier. We don't even know who you are — just an anonymous public key. If we got hacked tomorrow, attackers would find encrypted noise and anonymous keys. Nothing useful.
Frequently Asked Questions
