A film development companion app that provides precise timing control and guided workflows for film developers. It simplifies each step with clear, color-coded instructions, allowing users to adjust settings easily and ensure precision throughout the development.
BACKGROUND
The rise of film photography
calls for precise timing.
The resurgence of analog photography has sparked demand for tools that simplify home development. Among all variables, timing remains one of the most critical for achieving consistent results.
PROBLEM
Existing tools create friction in home film development
Traditional timers are bulky and not designed for home use, while smartphone timers require constant manual setup. This makes film development more time-consuming and prone to mistakes.
OPPORTUNITY
How might we streamline the film development process, increasing efficiency and precision, while providing photographers with a clear, guided system to enhance their workflow?
RESEARCH
The timing logic in analog film processing
This diagram illustrates how complex film development timing can be. With multiple stages and agitation intervals, users are forced to reset timers constantly — making the process tedious and error-prone.
COMPETITIVE ANALYSIS
To understand where current solutions fall short,I analyzed existing timer apps to identify usability issues like weak hierarchy, unclear navigation, and limited beginner support, while also noting strengths like clear task flow and readable design.
USER INTERVIEW
To better understand user pain points, I interviewed photographers who develop their own film. These conversations uncovered key frustrations with current tools, including outdated design, poor usability, and a lack of clear guidance.
IDEATION
I created this user journey map to visualize how photographers interact with the app — from exploring community presets to setting up custom timers.
Moodboard
Drawing from Leica’s timeless minimalism, I applied a black-and-white palette to convey precision and simplicity. This design approach reduces the complexity of film development, making the process feel more approachable and intuitive.
Development
I designed a layout that shows the step overview before the timer begins, giving users a clear understanding of the entire process.
From Concept to Final Mark
The Filmflow logo evolved through iterative exploration of type and dial motifs inspired by analog cameras. I tested various typography styles for clarity and character, alongside circular dial concepts to capture precision and tactility.
Final Product
Designed for Developers
Filmflow is a companion app that streamlines film development with customizable timers and guided, color-coded workflows. It ensures accuracy at every stage, reduces errors, and helps photographers focus on their craft with confidence.
Presets
Create a timer that fits your process
Easily build a new preset by selecting your developer, entering each step, and saving it for future use.

Start quickly with saved timers
Choose from your library of presets, review the details, and begin developing with just one tap.

PROCESS
Stay on track with color-coded guidance
Each stage of development is paired with a distinct color, helping users instantly recognize when to wait, prepare, or agitate.
