When the plan slips, Fortiv tells you what to change.
You don’t need more willpower. You need a plan that survives travel, dinners out and bad weeks — and something that notices when it stops fitting.
Fortiv watches strength, cardio and consistency together. When one starts slipping, it names a single change to make this week — one lever, not a whole new plan. You decide whether to pull it.

It reads your week and tells you
the one thing to change.
Every other app either nags you or ignores you. Fortiv watches strength, cardio, and adherence together — and when the data stops backing your goal, it hands you a single lever to pull. It never changes your plan behind your back. You decide.
74% adherence, and no guilt trip. You’ve been missing sessions, not slacking in them. Fortiv finds the real reason — the plan didn’t fit your week — and offers a lighter plan, not a lecture.
93% adherence, and recovery running on empty. Most apps reward the streak and ignore the burnout risk. Fortiv catches it first — take the foot off the gas this week, protect what you’ve built.
15% adherence, and still no lecture. Work trip, sick kid, whatever — Fortiv doesn’t make you catch up on three weeks at once. “Everything slipped. Pick one thing.” That’s the actual copy, verbatim.
Same engine, every direction. Missing sessions, burning out, or falling off completely — it catches the pattern before you do.
Your chain survives
bad weeks
Recent sessions count more than old ones. Miss a week — score dips. Come back — it recovers. The chart shows the whole story. You decide when to push and when to back off.
Lifts that pick up
where you left off
Fortiv reads your last session and sets the next one — weights, reps, and rest dialed in. You show up and lift. The planning is already done.
Cardio that builds
a base, not burnout
Zone 2 is the easy, sustainable cardio that adds years to your engine. Fortiv keeps the target honest and tells you you’re drifting off it — no guesswork, no hero workouts.
See the trend,
not the noise
Weight bounces day to day. Strength compounds over months. Fortiv shows the line that actually matters so you can trust the long game and keep going.

Days you can train, equipment you have, where you're starting. Two minutes, once.
Train the plan
Strength and zone 2, built around the days you actually have that week.
Fortiv spots drift
When strength, cardio or consistency starts slipping, Fortiv names the one change worth making. You decide whether to make it.
Questions,
answered.
How is this different from the fitness apps I’ve already quit?
Those apps assume you’ll follow the plan. Fortiv assumes some weeks you won’t. It watches strength, cardio and consistency together, and when the plan stops fitting your life it names one thing to change — instead of letting you quietly fall off.
Will it nag me or change my plan on its own?
No. Fortiv surfaces one recommended change when it sees drift. It never applies it for you and it never edits your plan behind your back. You’re an adult — you make the call.
Who is Fortiv for?
Adults 35–55 who want real strength and longevity without reorganizing their life around the gym.
I only have 2–3 days a week.
That's the design point. Plans are built around the time you actually have — not an idealized schedule.
Do I need a full gym?
No. Fortiv adapts to what you've got — a full rack or a single pair of dumbbells.
Is it iOS only?
Yes — Fortiv launches on iPhone. Android is on the roadmap.
