ErgSpeed is the training log built for indoor rowers. Log every row in seconds, see exactly how you paced it, and watch your fitness grow week by week. SCAN THE MONITOR Take a photo of your Concept2 PM3, PM4, or PM5 results screen and ErgSpeed fills in the rest: distance, time, split, stroke rate, every split, every interval, and every rest. Long workout? Photograph each screen in any order. The scanner tells you when it has them all and asks for another photo if a split is missing. Your photos are saved with the session. LOG IT YOUR WAY Prefer to type? The rowing keypad formats times as you go, so 7124 becomes 7:12.4. Log single-distance, single-time, and Just Row pieces, or distance, time, and variable intervals. Split and watts are calculated for you, and ErgSpeed checks that your splits add up. Record the machine you used, whether it is a RowErg, a WaterRower, or one of your own. SEE HOW YOU REALLY ROWED Every session shows your average split front and center, a pace strip of every split and rest, and a table showing which splits were faster than average. Compare against every past row of the same workout, see your personal best, and jump to your most recent attempt with one tap. YOUR TRAINING AT A GLANCE Home shows this week's meters against your weekly goal, your latest row, and twelve weeks of training as a color grid. Your goal syncs across your devices with iCloud. HISTORY AND FILTERS Every row, grouped by month, with a mini pace strip on each one. Filter by workout type, distance, time piece, split range, stroke rate, machine, and date to find any session fast. CHARTS AND STREAKS Weekly meters, your best 2K over time, and your yearly totals. Keep your streak going week after week. YEAR IN PIXELS Your whole training year in one grid, with each day shaded based on how far you rowed. Share it as an image. POWER PROFILE Your best watts from 1 minute to 1 hour and from 500 meters to 6K, so you know where you are strong and where to focus. RACE PLANNER Pick a distance or time, set a target, and shape your pace: go out hard, settle in, then sprint. See the plan as a chart, save it, and row it live with a segment-by-segment race screen. CALCULATORS Calculate time, split, distance, or watts for any piece. Premium adds training paces, heart rate zones, calories, boat class conversion, and drive ratio. SHARE Turn a session, your Year in Pixels, your Power Profile, or a calculation into a clean image to share. PREMIUM ErgSpeed is free to use.

Tired of texting strangers a photo of your passport? Same. IDfier lets you verify your ID once, then share a verified version of yourself with anyone who needs it, without handing over the document itself. How it works: 1. Scan your passport, national ID, or driver's license. Tap your phone to the chip if it has NFC. Take a quick selfie so we know it's you. 2. Build the things you want to share. An age check. Just your name. Full ID. A driver's license. Whatever the situation calls for. 3. Send it. QR code in person, link or short code online. They see verified data, not a screenshot. That's the whole thing. What people use it for: β€’ Meeting someone from a marketplace or dating app and wanting to know they're real β€’ Proving they're over 18 without showing their personal number and birthday β€’ Renting a place, signing for a delivery, picking up a package β€’ Onboarding to platforms that ask for ID without uploading documents to who-knows-where β€’ Creators and freelancers who want a public profile that says "I'm a real person", not just another link-in-bio Three trust levels: Bronze covers the document scan and face liveness check. Silver is for BankID users in Sweden. Gold adds a face liveness check to Bronze. The more you verify, the more weight your shares carry. Login with IDfier: Some sites and apps let you sign in by scanning a QR code with IDfier. You see exactly which fields they're asking for and approve each one. No more uploading ID photos to random websites. Pricing: The first 10 exchanges are free. After that you top up with credits or subscribe for unlimited use. We don't sell your data, that would defeat the point. A few things worth saying: β€’ Your documents stay on your device. We don't keep copies. β€’ The app locks behind Face ID or Touch ID. β€’ Sweden: BankID works as a shortcut for the initial verification. β€’ Everywhere else: we read documents from over 200 countries. If something's broken or weird, the feedback button in your profile goes straight to us. We are all ears. β€” The IDfier team
