CronOptimal

CronOptimal — Smart Time Tracking for Field Teams CronOptimal makes clocking in and out effortless for employees who work across multiple job sites. No more paper timesheets or manual logs — just scan and go. Track time your way Start and stop your timer by scanning a QR code or tapping an NFC tag at the job site. It's instant, accurate, and eliminates guesswork about when work actually began or ended. Automatic arrival detection CronOptimal uses your location to detect when you've arrived at a client site and notifies you the moment tracking can begin — so nothing gets missed, even if you forget to open the app. See where you're working An interactive map shows nearby job sites and clients, helping you find the right location and confirming you're in the right place before starting a shift. Log costs on the go Snap a photo of a receipt or invoice and log it directly against a job — purchases, administrative costs, or workforce expenses — so nothing gets lost between the field and the office. Stay on top of your hours Review your daily, weekly, and monthly hours at a glance, so you always know where your time has gone. Built for how you work Fast QR and NFC scanning — no typing required Real-time location-based arrival detection Photo-based cost and receipt tracking Daily, weekly, and monthly hour summaries Available in multiple languages Whether you're on a construction site, visiting clients, or managing a mobile workforce, CronOptimal keeps time tracking simple, accurate, and out of your way — so you can focus on the work. Note update - 21.07.2026 Regarding the spam issue with the app, before there was another app under the name called CronOptimal under the davany user. As of now, that version of the app is not available to download because the apple developer subscription is not being maintained anymore on the account that uploaded it. The development and deployment of that same app was moved to this account and is still owned by the same entity ( davany ) but they are not in charge of the development, instead we are doing it for them. I've updated the other issues stated in the last review, only difference from the youtube demo is that we've removed the background location ( third permissions ) from the app in the beginning of the video.
