Strong and Hevy are the two loggers most lifters compare, and both are shipped, mature products. Zyra Workouts is neither yet: it is in development, iOS-only, and not on the App Store. Zyra builds Zyra Workouts, so this page is our product beside two established ones, with every Strong and Hevy fact taken from their own pages on the date above, every Zyra Workouts fact taken from its source code, and the status stated plainly rather than in a footnote.
The one-line summary
Strong is a lifter's toolkit with plate and warm-up calculators and open export; Hevy is a routine planner with a community, watch apps and a web app; Zyra Workouts is an offline-first logger built around set-level detail, gym-aware plate math and a readable progression rule — and it is not available yet.

Where Strong and Hevy are stronger
They exist. Both are on the stores, on Android, and on the wrist. Zyra Workouts has none of those three today, and a logger you cannot install has no features at all.
Hevy's breadth. A web app for planning at a desk, Wear OS as well as Apple Watch, a library with exercise videos, and a social layer where you follow other athletes and save their routines3. If training is social for you, that column is the one that matches.
Strong's toolkit and openness. Plate and warm-up calculators, supersets, RPE, body measurements, Apple Health and CSV export are all on its listing2, and the account is free1. It is the closest of the two to what Zyra Workouts is attempting, with years of head start.
Track record. Both have long release histories. Zyra Workouts has a codebase.
What Zyra Workouts does differently
Set detail. Every set carries a type — standard, warm-up, drop, myo-rep or failure — a side for unilateral work, full and partial rep counts, and an RIR (reps in reserve: how many more you could have done) mark. Warm-ups are excluded from working volume automatically; drop sets are linked to their parent set. The RIR / RPE converter on this site uses the same clamps the app does.
Plate math against your gym. You tell the app which plates your gym has (20, 15, 10, 5, 2.5, 1.25 kg by default) and which bar (10, 15 or 20 kg), and can save several gyms as named profiles. Every load is then decomposed against that inventory, and a weight that cannot be built from your plates says so instead of pretending. The plate calculator here runs the same routine.
A progression rule you can read. Smart Progression looks at your last working sets for an exercise and the program's target — a rep range and an RIR. It computes a ceiling: the midpoint of the rep range plus the RIR target. Beat the ceiling on every set and the next load steps up — by one pair of your smallest plates for a barbell, by 2 kg for a stack or dumbbell; fall under the bottom of the range and it steps back one step; anything between holds. Bodyweight exercises progress by reps, since there is no load to move. No history, no recommendation.
Offline, no account, your data. Sessions are written to the device set by set, so a crash loses at most the last keystroke. There is no sign-in wall; an account is an optional backup. CSV export writes one row per set with the set type labelled.
No social layer, by design. That is a preference, not a feature gap we intend to fill.
Status, plainly
Zyra Workouts is in development. It is not on the App Store, has no release date to announce, no Android or watch version, and no import from other apps (CSV import from Strong and Hevy is on the design list, not built). The features above are in the source code; the screens may change before release. When it ships, this page will be updated the same day.
The short version
Strong and Hevy are shipped, multi-platform loggers: Strong leads with a lifting toolkit, CSV export and a free tier capped at three routines2; Hevy leads with routines, community, watch apps and a web app3. Zyra Workouts is an in-development iOS logger built around set-level detail, gym-aware plate math, a readable progression rule and offline data ownership — not yet on the App Store. Zyra builds it; the table shows the gaps as clearly as the differences. Training-tool overview only — not medical advice.
