Independent product studio · Istanbul

Small studio. Serious products.

Plainwork designs, builds and ships its own apps and games — for iPhone, Apple Watch, Android and the web. Native where it matters, honest with every number, finished down to the last string of copy.

Work

Three products so far.

Each one gets its own identity — a floodlit board for Grido XI, black ink on white paper for Fazlo, a calm night for SleepWell. Underneath, the same standards: real data, careful words, and nothing pretending to be more than it is.

Football trivia

Grido XI

Two clubs, one player. A daily football grid, with live 1v1 when one grid is not enough.

  • One grid a day

    Nine cells, nine guesses, no do-⁠overs. Everyone gets the same grid, and the answer nobody else thought of scores more.

  • Live when you want it

    Take turns claiming cells against a real opponent. Three in a row wins, and a rated win moves your rating.

  • Fair by design

    Daily scores are worked out on the server, practice bots are always labelled, and nothing sold in the app helps in a rated match.

  • iPhone Available
The Collection tab with 50 cards, counters for Legend, Rare and Common cards, the closest squad to complete and club squads filtered by country.

Training & nutrition

Fazlo

Pick a phase. Measure. Progress.

Training, calories and measurements in one place — built around the phase you are in.

  • Tells you what to lift

    Today’s session is waiting on the first screen. Your last session pre-⁠fills every set, and at the top of the rep range Fazlo suggests the next weight.

  • Shows where you stand

    Weight, waist and lifts plotted against the target line for your phase — lean bulk, maintenance or cut.

  • Fits your gym

    104 exercises, filtered by the equipment you actually have. Machine taken? Starred alternatives are one tap away.

  • Web Available
  • iPhone Available
  • Android Available

Sleep & insomnia

SleepWell

A 5-week insomnia program, inside a sleep tracker that only needs your iPhone.

  • No watch required

    Put your iPhone on the nightstand. SleepWell reads the night from motion and sound, and picks up snoring and sleep talking.

  • A program, not a dashboard

    Five weeks of CBT-⁠I — short lessons, a sleep diary and a sleep window set from your own nights.

  • Private by design

    Recording is off until you turn it on, and clips never leave your phone. No account, no ads.

  • iPhone Available
  • Apple Watch Available
  • Widgets & Live Activity Available
The Track tab with tonight’s bedtime and alarm, a notice that smart wake is ready, and a Start Sleep Session button.

Approach

How we build.

Five rules every product is held to — each shown with a detail from one of our own apps.

  1. Show the working.

    Every number should be able to explain itself. If a score, a target or a suggestion cannot say where it came from, it is not ready to ship.

    Fazlo’s plan card: a lean bulk at 3,061 kcal a day, protein 160 g at 2 g/kg, carbs 425 g as whatever calories are left, fat 80 g at 1 g/kg, calculated from 80.1 kg.
    Fazlo Every target carries its reason — and the weight it was calculated from.
  2. Be honest about limits.

    When a measurement is an estimate, the interface says so. We would rather show less than imply more.

    SleepWell’s note under the sleep stages chart: stages are estimated from motion when tracking with iPhone alone (REM isn’t estimated); duration, efficiency and score are unaffected.
    SleepWell Written under the chart itself, not tucked away in a help page.
  3. Private by default.

    A product should work before it asks for anything. Accounts are optional, and data stays on the device unless you decide otherwise.

    Fazlo’s welcome screen: with an account your data is backed up to the cloud; you can start without one too — everything stays on this device.
    Fazlo No sign-⁠up wall. The account is there for backup, not as the price of entry.
  4. Built on evidence.

    We start from established methods, say which ones we use, and leave out the claims we cannot support.

    SleepWell’s program header: guideline-recommended, 5 weeks to better sleep, evidence-based cognitive behavioral therapy for insomnia.
    SleepWell The program names its method on its first screen. Week 1 is free, so anyone can check.
  5. Keep it fair.

    A result only means something if everyone played the same game. Nothing for sale changes the outcome, and anything automated is labelled as what it is.

    Grido XI’s Daily Grid card on the first screen: same four grids for everyone, nine guesses each, with a Play button for each difficulty and the time until the next grid.
    Grido XI Said on the first card of the first screen. The points are worked out on the server.

Studio

We do every part ourselves.

Research, design, engineering and release all happen in-house — from the first prototype to App Store screenshots in nine locales. It keeps every decision close to the details.
