AddFive - Just add 5 (kg | km | min)

Every fitness app I tried handled one thing. None applied the math of progressive overload to everything. So I built AddFive: 7 algorithms for strength, running, HIIT and calisthenics. I didn't want a spreadsheet, so each exercise is the star of the UI. I didn't want robotic TTS, so I spent way too long casting actual voice personas on ElevenLabs. 9 coaches, 2,197 unique quotes. Live Activities, Apple Health. Local-first, no account.

Hey Product Hunt! šŸ‘‹ I'm Matthieu, a laser physicist and R&D engineer from Bordeaux, France. By night, I build iOS apps. I was using a generic workout tracker that applied progressive overload for strength. But then I wanted to improve my cardiovascular health as a former smoker, and no app handled both running & lifting with real progression math. So I built AddFive. It covers everything: šŸ’Ŗ Strength: adds weight after consistent performances šŸƒ Running: pushes pace, distance, or time 🤸 Calisthenics: advances you to the next variant automatically šŸ”„ HIIT: adds rounds after x consecutive successes I didn't want a spreadsheet UI. So each exercise is the star of the show. I found a massive library of stick figures on Flaticon, full of character, and used them throughout the app. The native apple TTS during the workouts felt robotic. So I spent way too long drafting actual coach personas and selecting their voices on ElevenLabs. 9 coaches, 2,197 unique quotes. The program library includes 100% free programs like "Smoker's Rehab" (that's autobiographical) and "Silver Strength" for older lifters. Built solo. Local-first. No account, no cloud. šŸŽ PH exclusive: lifetime access at 50% off (€49.99 instead of €99.99). DM me and I'll send you a personal link. What type of training do you do? Lifting only, or do you mix it with running?
