Transform your iPhone into an enlarger timer using Chronodev. Chronodev uses HomeKit-enabled wall plugs and lightbulbs to control your enlarger and safelights.

This one costs the price of a wi-fi wall plug. - Control your enlarger and safelight with your iPhone or iPad - Expose prints accurately using the HomeKit-enabled timer - Manual enlarger control for focusing - Use the metronome for dodging and burning - Adjust times using EV stops - Automatically create test strips with incremental exposures, and keep track of exposure times using a handy graph - Automatically turn your safelight off when exposing/focusing - Voice control support for hands-free development - Safe to use in black and white darkrooms when using iOS's built-in red color filter A HomeKit-enabled wall plug and/or lightbulb is required to use all features of this app. Some features (like a basic timer and EV stop calculations) are available without a HomeKit-enabled device.

Verdict
The clearest difference is in-app purchases: Chronodev at none against Phlow's 11. Chronodev also leads on review sentiment (100% vs 81%). Phlow's advantage is rating (4.9 vs 4.5) and ratings volume (2.6K vs 2). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Phlow sells 11 in-app purchases, starting at $1.89 per 7 days. Chronodev asks for nothing beyond the download.
Phlow holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Phlow has 2.6K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 81% of Phlow's written reviews are positive against 100% of Chronodev's, so the app with the better star average is not the one people write more warmly about.
Phlow ships an update every 8 days, Chronodev monthly. The most recent releases landed on September 23, 2026 and June 7, 2026 respectively.
