Eflir

Eflir tells you what to do in the gym, and why.

Most gym apps are notebooks: they record what you did, but they hold no opinion. Eflir does — backed by evidence. We rank the best complementary exercises for your sport from scientific literature, anatomy, and biomechanics, and every rating carries its reference.

Pick your discipline. Hypertrophy, powerlifting, swimming, soccer, combat sports, basketball, cycling, rowing, track and field, volleyball, or tennis. Eflir shows you which exercises give the most back to your sport, ordered by evidence — not by trend.

Train on your terms. Sensitive lower back? A shoulder you had operated on? Only dumbbells at home? Mark your restrictions and Eflir filters out what doesn't suit you and suggests substitutes. No guesswork.

Build your routines. From discipline templates or from scratch. Yours, editable, with no paywalled templates hidden inside.

Track your progress. Sets and loads with estimated 1RM and personal records, body measurements with progress charts, and progress photos with a side-by-side comparison.

Your privacy isn't a promise — it's the architecture. Eflir works with no account and no connection. Your workouts, measurements, and photos live only on your phone. No servers, no analytics, no ads. You can export everything to a local backup whenever you want — your data is yours.

Eflir is not a substitute for medical advice. Consult a professional before starting an exercise program, especially if you have injuries or health conditions.
