Entscheid
One toolbox, seven tools
Different decisions call for different strategies. Pick the tool that fits the problem — each one is backed by a proven algorithm and explained in plain language.
Pros & Cons
Weigh each argument, add a probability, and get a clear verdict — not just a longer list.
Best Combination
Bayesian optimization finds the sweet spot of any recipe — espresso, workouts, ad budgets — in as few tries as possible.
Scheduling
Eight classic scheduling algorithms — WSJF, earliest due date, shortest job first and more — ordering your tasks for you.
Stopwatch
Time competing routines, then compare them on speed and consistency — mean, spread and range at a glance.
Correlation
Log simple yes/no observations and learn what actually moves your sleep, mood or energy — and by how much.
Optimal Stop
Apartments, hires, parking spots: the 37% rule tells you when to stop looking and commit to the best you've seen.
Explore / Exploit
A multi-armed bandit for repeat choices — balances trying new options against sticking with proven favorites.
+ AI Assistant
Chat with your decisions: an optional assistant that sees the tool you're using and helps you take the next step.
Every tool ends in a verdict
No more staring at a tied list. Weights and probabilities roll up into a plain-language recommendation — “Pros outweigh cons, 22.1 to 14.4” — so you always know where you stand.
- Weight every argument from 1–10
- Discount uncertain arguments with a probability
- Optionally count only the strongest criteria
Run experiments like a scientist
Tell the app what you can vary, log each attempt, and Gaussian-process optimization suggests the most promising next combination. Insight charts show how the search converges and what each parameter does.
- Smart “try this next” suggestions after every observation
- Convergence chart shows when you can stop experimenting
- Per-parameter predictions with uncertainty bands
Let an algorithm order your day
Your todo list, sorted by computer-science classics instead of gut feeling. Pick the strategy that matches your situation and the app re-orders your tasks — done items fall to the bottom.
- 8 algorithms: WSJF, earliest due date, critical ratio, shortest & longest processing time, highest priority, FIFO, manual
- Each task carries complexity, priority and due date — only when the algorithm needs them
- Every algorithm explains when it's the right choice
Time it. Compare it. Settle it.
Bike, U-Bahn or e-scooter? Stop debating and start measuring. Time each alternative over a few days and the app crowns the fastest and the most consistent option, with full statistics behind every badge.
- Compare any number of activities side by side
- Expected time, range, standard deviation and variance per activity
- Timers keep running even if you close the app
An assistant that knows
which decision you're on
Swipe from the right edge to chat. The assistant sees the tool you're currently viewing, can read its data, and helps you interpret results or log the next observation — like a decision coach in your pocket.
- Bring your own key. Connect your own AI provider account; requests go straight from your phone to the provider — never through our servers.
- Context-aware. Ask “which commute wins?” while viewing your stopwatch and it answers from your actual measurements.
- Hands-on. It can add tasks, log trials and suggest what to try next — always visible, always undoable.
Feeling overwhelmed? Help is one swipe away.
Every tool links to a plain-language explainer — the idea, the math, and when to use it — right inside the app, or at docs.entscheid.io.
Frequently Asked Questions
How do you handle my data?
Everything you enter is stored only on your device — we run no servers, keep no accounts and use no third-party analytics. If you enable the AI assistant, your chat goes directly from your device to the AI provider you configured with your own key; we never see it. Details in our privacy policy.
This is a lot — where do I start?
Start with a question you actually have (“should I take the offer?”, “which route is faster?”), pick the matching tool from the + menu and just fill it in. The documentation — also available by swiping inside the app — explains every tool with examples, and the AI assistant can walk you through your first decision.
What's new in the latest version?
A lot: a redesigned interface, the new Explore / Exploit tool, an optional AI assistant, eight scheduling algorithms, multi-activity stopwatch comparisons, and insight charts for the optimizer — plus a much faster optimization engine under the hood.
I have an idea for the app — can I suggest it?
Please do! The app is under active development and we prioritize from user feedback. Reach us at contact[at]entscheid.io or in our Reddit community.
I bought a new phone — how do I transfer my data?
Since data lives only on your device there's no automatic sync yet. We're working on an export/import solution; meanwhile write to contact[at]entscheid.io and we'll help you move your decisions over.
Is the app free?
Yes! And no ads. The optional AI assistant uses your own provider account, so any AI usage is billed by your provider, not by us.
