Lightweight › Strong alternative

Switching from Strong

The Strong alternative you don't train alone in.

Strong nails the basics — a clean, fast logger, and one of the best on iOS. But it's a solo app: no friends, no feed, no reason to open it between sets. Lightweight keeps the fast logging, imports your Strong history automatically, and adds the part that makes you show up — it maps your gyms, ranks your training, and puts your crew right there with you.

Why lifters switch

Everything Strong does well, plus the reasons to actually keep it open.

You don't train alone

Strong is a solo logbook. Lightweight is a crew: a feed of real achievements, kudos on your PRs, and friends you can see training right now — opt-in and private by default.

Your gyms, on a globe

Every session is tied to the gym it happened in. Train somewhere new and it stamps your passport — a map of every gym and country you've lifted in, not just a list of workouts.

Records that know the gym

A lucky machine number on hotel plates isn't a PR at your home gym. Lightweight keeps records honest by remembering the equipment and gym behind every lift.

Status you can't buy

Earn permanent ranks by actually training, with a transparent breakdown and per-gym leaderboards. The one number in fitness that means you showed up.

Bring your Strong history with you

Years of logs shouldn't be trapped in one app. Lightweight auto-detects Strong's CSV export — both the older comma format and the newer semicolon one — so your workouts and PRs come across cleanly.

Export from Strong

In Strong, open Settings and export your workout data as a CSV file.

Import into Lightweight

Open Lightweight, choose Import, and pick the CSV. It recognises the Strong format and maps your exercises automatically.

Pick up where you left off

Your history and personal records are there — now tied to the gyms you trained at, with a crew around them.

Where Strong still wins today

  • It's out now. Strong is available today on iOS and Android. Lightweight is launching — join the waitlist to get in early.
  • A great Apple Watch app. Strong's watch experience is one of the best around. Lightweight runs a live workout activity on iOS but doesn't have a full watch app yet.
  • Dead-simple and proven. Plate and warmup calculators, a famously clean interface, and years of polish. If you want a pure solo logbook and nothing more, Strong is hard to beat.

Questions

Can I import my Strong data into Lightweight?
Yes. Export your history from Strong as a CSV and import it into Lightweight. The importer auto-detects Strong's export — both the older comma format and the newer semicolon one — and maps your exercises, sets, weights and dates, so your history and records come with you.
Is Lightweight free?
Yes. The full logger, unlimited routines, progress charts on your recent training, lifetime personal records and the entire gym directory are free. Lightweight Pro adds all-time history and coach-grade, gym-aware analytics for £2 a month or £18 a year.
How is Lightweight actually different from Strong?
Strong is an excellent solo logger. Lightweight keeps the fast logging but adds a social and location layer Strong doesn't have: a crowdsourced global gym map, a gym passport of every gym and country you've trained in, records that respect the gym and equipment you used, permanent earned ranks, per-gym leaderboards, friends and a feed, and optional WHOOP and Oura recovery context.
Is Lightweight available on Android?
Lightweight is launching on iOS first, with Android to follow. Join the waitlist and we'll let you know the day your platform is live.
