Your programming is sharp; the system holding it isn't.
Brilliant blocks get stuck in brittle spreadsheets and lost between sessions. Phaserr keeps the plan, the delivery, and the logs in one place.
The program-builder app for strength and conditioning coaches
Plan periodized blocks, auto-calculate loads, deliver sessions to athletes without an app install, and turn every logged rep into your next decision.

Recalculating loads by hand eats your evening.
Every %1RM, RPE target, and warm-up ramp is math you redo per athlete. Phaserr calculates it the moment you set the basis.
You can't see who actually did the work.
Once a program leaves your hands you're guessing at compliance. Phaserr surfaces missed, skipped, and off-load sets so you coach on facts.
A growing roster outgrows a folder of files.
Managing ten athletes across ten spreadsheets doesn't scale. One tool holds every athlete, block, and record together.
Periodization down to the warm-up set
A mesocycle and block builder that thinks the way you program — waves, intensifications, deloads — with loads that fill themselves in.
- Plan blocks ahead, re-order them, and keep the full training history
- %1RM, RPE, and linear progressions with auto-calculated loads
- Auto-generated warm-up ramps for every main lift
- Save any block as your own reusable template
Deliver sessions without an app install
Send today's session or a whole block by link. No athlete sign-up, no download — and revoke access whenever you want.
- Share by link — athletes open and log, no account required
- Printable PDF day sheets for the gym floor
- Push one day or an entire training block
- Revoke a share link any time
Every logged rep becomes a decision
Compliance and records feed straight back into programming, so the next block starts from what actually happened.
- Spot missed, skipped, under- and over-loaded sets
- Track personal records, 1RM and AMRAP history by lift
- Logged results flow into the next block's loads
- Keep every issue and note in one place for review
Start from a proven block, not a blank page
Built-in program templates you can load, edit, and assign in minutes — every load basis stays yours to set.

Frequently asked questions
What is an app for strength and conditioning coaches?
It's software built for programming, not general fitness logging. A coach designs periodized blocks, sets loads by %1RM or RPE, delivers sessions to athletes, and tracks compliance and records. Phaserr does all four in one place, so the plan, delivery, and results stay connected instead of scattered across spreadsheets and chat.
How is Phaserr different from a spreadsheet?
A spreadsheet stores numbers; it doesn't calculate loads, deliver sessions, or tell you who trained. Phaserr auto-calculates %1RM, RPE, and warm-up loads, shares sessions by link or PDF, and flags missed or off-load sets. The programming logic and the tracking live together, so nothing is lost between weeks.
Do my athletes need to install anything?
No. Athletes open a share link in any browser to view and log their sessions — no app store, no account required. You can also export a printable PDF day sheet. Share a single day or a whole block, and revoke the link whenever you want.
Can I program by percentage and by RPE?
Yes. Phaserr supports %1RM, RPE, and linear progressions, and auto-calculates the resulting loads and warm-up ramps from the basis you set. You can mix approaches across a block — percentage waves on main lifts, RPE on supplemental work — without recalculating anything by hand.
How much does Phaserr cost?
Phaserr is free to use. Create an account to get started. There's nothing to configure or pay for — you build programs, deliver them, and track athletes at no cost.
Is there an AI assistant?
Yes. Phaserr includes an AI assistant that understands periodization — mesocycles, blocks, waves, and load progressions — so it can help you draft and adjust programs in the language you already coach in, rather than treating every set as a generic entry.
