On a relay team? ETA counts down to your teammate reaching the exchange, on the Lock Screen too, and saves the pace each leg was really run. Pro is a one-time purchase.
Distance, time, pace and speed, always in sync. Change any one and the others follow. A lock holds the value you care about while you work out the rest.
On a relay team, or waiting for a runner at a race? ETA tells you the clock time they reach you, with a live countdown that carries on to the Lock Screen and up to three alerts. Tap when they arrive and the leg is saved with the pace they really ran.

PRO (one-time purchase, no subscription)
• Splits: plan even, negative or positive splits at any interval from 100 m to 10 miles, by halves, thirds, quarters or fifths, or an interval of your own, then export the table.
• ETA: made for relay exchanges and race spectators. Each runner gets a card with the arrival clock time, a live countdown, estimated progress, up to three alerts and a note. The countdown also runs on the Lock Screen, in the Dynamic Island and as a badge on the main screen.

It's just me, a runner, building the pace calculator I want to use. Send feedback from inside the app and I'll answer.
I’m not sure why other people are complaining about the update — you can still use the old version if you go to settings.The new version lets you do bidirectional conversions, and is a big step up. I use this app all the time for training, it’s great!
It's like a pace calculator that's simple
Huck Pituey
It does one thing. It does it well. It doesn't try to get me to buy anything. Win, win, win!1. Enter the distance. Tap to toggle miles vs km.2. Type in the hours (if any), minutes, and seconds.3. View your pace (and speed).Bonus: you can directly edit your pace to see the corresponding time for that distance!Suggested improvement: I think it might be more convenient for some users to have spinny wheels to enter the hours, minutes, and seconds, and also to subsequently edit the pace to see a revised time.3.
Was a good app but new update made it trash
nonamechino99
It was the best app at calculating paces and converting between miles and kms; but, the new update added a ton of extra useless stuff. Now its messy, complicated, ugly and confusing. The one thing it was good for it wont do easily no more. If there were any app awards for WORST update you guys would win it in a heartbeat. I logged back into the app store just to review this trash that you came up with. Slow applause for the designer and dev team that took a great product and made it useless. Congrats!
Developer Response
I’m sorry you don’t like the updates, but thank you for the feedback. The original app was released over 10 years ago and was getting difficult to maintain. You should be able to do everything in the latest version, as easily or easier, than in the original. If there is anything specific I can do to make the new version better for the way you use the app, please send me feedback from within the app and I’d be happy to do what I can.BTW, it’s just me. No team. No corporate owners. I’m just a runner who is trying to make the best pace calculator, so any constructive feedback really does help.
Perfect

I wish there were more apps like this out there. It’s simple and does exactly what I want. Does try to sell me anything else, doesn’t want access to my contacts. Perfect.
• Classic view: fixed visual defect at the bottom of the screen
