2.11.0 1 day ago
See your progress, not just weigh it: progress photos and body measurements are here.
– Progress photos stay on your phone. We never upload them anywhere and nobody else sees them
– Your Start and Now shots sit side by side on the progress screen, with the difference between them
– Body measurements: waist, chest, hips, upper arm and thigh, saved by date, with the whole history one tap away
– Weight, photo and measurements go in together, and you can backdate an entry if you stepped on the scales yesterday
– New goal, Build muscle: calories and protein are set for putting on mass instead of losing it
The app speaks Korean now, and favourites no longer double your calories when you open a meal twice.

• Text and voice logging works a lot better too, especially when you already know the grams and macros
• Added Chinese, Simplified and Traditional, and cleaned up translations across the other languages
If something feels off, email us at hello@calzen.ai and we'll sort it out.
2.10.12 2 Sept
Hey! Last time we promised to fix dictation. Done.
• Dictation now works on all devices, not just the newer ones
• Added six languages: Romanian, Hungarian, Latvian, Lithuanian, Finnish and Serbian
If something feels off, email us at hello@calzen.ai and we'll sort it out.
2.10.11 12 Aug
Hey! A little cleanup this time:
• Fixed some bugs that were getting in the way
• Made food recognition more accurate
And yeah, we heard you: the next update will fix dictation for everyone it wasn't working for. Already on it.
If something feels off, email us at calzen@42apps.io and we'll sort it out.
2.10.9 7 Aug
We fixed a few small translation inaccuracies and a couple of minor bugs you reported. Thanks for helping us make the app better. Have an idea or found a bug? Write to us at hello@calzen.ai, we read every message.
2.10.8 21 Jul
We reworked the first steps inside the app, so it's easier to find your way when you start. We also fixed a few small bugs. Right now we're working on making food recognition more accurate, and those improvements are coming in the next updates. Found a bug or have an idea? Write to us at hello@calzen.ai and we read every message.
2.10.7 16 Jul
We made the app more stable and fixed a few small bugs. If something isn't working or you have an idea, write to us at hello@calzen.ai. We read every message.
2.10.6 9 Jul
Now you can change how fast you want to reach your weight goal, right from your profile. CalZen updates your daily calories and macros the moment you adjust it. And if your pace sets your calories too low, we'll let you know and help you pick a safer target. Questions or ideas? Email us at calzen@42apps.io and we reply to every message.
2.10.5 8 Jul
We improved voice logging, so it's faster and catches your words more accurately, even if you clear the field while recording. We also fixed a few stability bugs. Questions or ideas? Email us at calzen@42apps.io and we reply to every message.
2.10.4 2 Jul
This update makes everyday tracking smoother and more dependable. Logging meals by text now works faster and more accurately, so adding what you eat takes less effort throughout the day. We also resolved a stability issue that affected some users on certain devices. Thank you for being part of CalZen, and we truly value every review and suggestion you share with us.
2.10.3 25 Jun
Small habits win. That's the whole idea behind this update.
Say hello to the CalZen Live Activity. Flip it on in your Profile and your remaining calories and macros (protein, carbs, fat) show up right on your Lock Screen as live rings, updating the second you log a meal. No need to open the app just to see where you stand. And in the Dynamic Island, your calories left for the day stay a glance away.
Here's a little trick that actually works: check your numbers before you order, not after. One look at how much room you've got and the call between the fries and the salad pretty much makes itself. No math, no guilt, just an easier choice.
We also cleaned things up under the hood, so CalZen stays fast and steady.
And honestly, we read everything. If something made your day, got on your nerves, or there's a feature you wish existed, tell us. Drop us a line at calzen@42apps.io or leave a review. Your notes genuinely shape what we build next, and we can't wait to hear from you.
2.10.2 23 Jun
Your calories are now always in sight — right from the Lock Screen.
• NEW: Live Activity — track your remaining calories and macros (protein, carbs, fat) at a glance on the Lock Screen and in the Dynamic Island, without even opening the app.
• Updates live as you log your meals, so you're always in control.
• Turn it on or off anytime in your Profile.
Plus bug fixes and improvements to keep CalZen fast and reliable.
2.10.1 11 Jun
You hop on the scales, head for the coffee — by the time you pour, the number's gone. Sound familiar? The + button on the home screen now logs your weight: tap it right off the scales, number's in before your coffee's done. We've also rebuilt the camera screen from scratch — open it and your food's right there in frame, no extra UI in the way, shutter's instant. CalZen tip: weigh in at the same time every day, first thing, before you eat — one day's noise, a week's the signal. Chase the trend, not the number. More good stuff to come. Tell us how it lands at hello@calzen.ai, we read every message ourselves.
2.10.0 6 Jun
A PDF nutrition report for 7 days, 2 weeks or 30. One tap on the share icon at the top of the main screen, and you get a clean document with macros, weight and the food diary day by day, with photos. People used to screenshot the main screen and stitch the days together — no more. Send it to a trainer, a nutritionist, a doctor or anyone who asks how you actually eat: clear and self-explanatory. Try it and tell me how it goes at hello@calzen.ai, I read every message personally.

2.9.0 26 May
Your diet doesn't break because of Friday pizza. It breaks because of that spoon of peanut butter on the fly, the handful of almonds round at a mate's, the latte on the way to work — the 300–500 calories that "don't count." Voice dictation was built for exactly that moment: hands busy, just say it out loud. Fibre is the other invisible piece of the puzzle: 25–30g a day, and satiety holds, digestion works, training goes easier. Which feature do you use most, and what would you tweak to fit your goals in CalZen? Email hello@calzen.ai — I read every message personally.
2.8.2 25 May
Sneaky glitches, jumpy taps, the odd typo — we hunted them down and squashed the lot. Quiet release on the surface, smoother under your finger. While you're here: we shipped fibre tracking in 2.7 and voice dictation in 2.8, and we genuinely want to know how they're treating you. What works, what bugs you, what's missing? hello@calzen.ai — every email lands on a real person at CalZen, and the features we hear about are the ones we keep building on.
2.8.1 23 May
Mouth full, fingers greasy, hands on the wheel — finally an excuse to talk to your phone. Voice dictation has landed: press and hold the big + on the home screen and just say what you've had. The least awkward way to confess that second slice of pizza. Heads up: voice mode is iOS 26 only. CalZen tip: the snacks you didn't plan to eat leak more calories than the dinners you actually cooked. Log those first. Ideas? hello@calzen.ai
2.8.0 19 May
Fibre now joins every food scan — track it right alongside protein, fat and carbs. We also gave the meal view screen a fresh coat of paint. Two things we want to apologise for and have already fixed: the loading screen got slow on the last build, and the home screen list sometimes got sticky to scroll. Both sorted — sorry about that. CalZen life hack: a handful of berries on your morning porridge ≈ 5 g of fibre, basically free — most of us are eating half of what we should. Ideas? hello@calzen.ai
2.7.8 17 May
Polished a few details under the hood — a quiet bridge release while the bigger update is brewing. Summer hack while you wait: pop a handful of grapes in the freezer. They turn into tiny natural sweets — sweet, crunchy, basically no calories. Stay close, something solid is coming next. Ideas? hello@calzen.ai
2.7.7 6 May
Quiet polish under the hood, calm and steady. Summer life hack while you wait: half your snack cravings in the heat are just thirst in disguise. Have a glass of water first, then decide. Bigger stuff is on the way next release. Stay close. Ideas? hello@calzen.ai
2.7.6 5 May
We made food scanning more accurate. CalZen life hack: the best summer prep isn't a crash diet in June — it's knowing what you eat in April. Your future beach self will thank you. Ideas? hello@calzen.ai
2.7.5 9 Apr
• Added support for new languages
• Fixed minor inaccuracies
We've received a large number of requests to improve food recognition quality — especially when photographing packaged food with nutrition labels showing weight, calories, protein, fat, and carbs. We're working hard to significantly improve our algorithms as soon as possible. Stay tuned!
2.7.4 7 Mar
Tuned things up under the hood. CalZen life hack: log your food before you eat, not after. You'll pick better portions — and won't have to google "calories in that thing I had for lunch" three hours later. Ideas? hello@calzen.ai
2.7.3 27 Feb
