Picking a restaurant with friends. Choosing a vacation destination with family. Voting on a team offsite location. When the decision has to be collaborative and everyone must buy in, ChoiceMap's group-voting model is exactly right. Decisio has no built-in collaboration — it's a solo tool.
ChoiceMap runs on both. Decisio is iOS-only. If half your group uses Android, ChoiceMap is your only realistic option.
For "where do we eat tonight" with 6 friends, you don't need AHP math. You need a lightweight way to stop the group chat arguing.
Career moves, big personal purchases, business strategy, investment choices — these are your decisions. Collaborative voting isn't the problem; thinking clearly is. Decisio's AHP pairwise comparisons force you to confront what you actually value, and the consistency check flags when you're rationalizing.
If you need to justify your choice to a boss, spouse, investor, or future self, "we voted on ChoiceMap" is weak. "I used AHP pairwise comparisons, here's the consistency ratio, here's the PDF of the analysis, and here's the Devil's Advocate critique I addressed" is strong. Decisio exports the whole reasoning chain.
ChoiceMap forgets the group decision the moment it's tallied. Decisio's Playbook captures Recipes (what worked), Principles (what you learned), and Outcome Tracking (were you right?). After 5+ rated decisions, it shows your personal Calibration Score. That's a feedback loop you can't build from group votes.
Decisio's AI suggests the criteria you might be missing, proposes options you haven't considered, and — crucially — plays Devil's Advocate against your top choice with specific, criteria-aware counter-arguments. ChoiceMap has none of this.
A workflow that actually works: use Decisio to do the hard analytical work yourself first. Identify the real criteria, run the AHP, see the ranking, address the Devil's Advocate critiques. Export the PDF. Then bring the PDF into a family discussion or team meeting where ChoiceMap (or a show of hands) confirms the group buys in. You've done the thinking; the group confirms the commitment.
Not in real-time. Decisio exports decisions as PDF, Excel, or Markdown, which you can share by email or chat. If you need live collaborative voting, ChoiceMap (or similar group-decision tools) is the right pick.
No. ChoiceMap uses direct scoring — each person rates each option. That's fine for capturing preferences, but it skips the mathematical rigor of AHP (pairwise comparison, eigenvector weights, consistency ratio). For rigor, you want AHP; Decisio is the only consumer iOS app that implements it fully.
Decisio. A career decision is fundamentally personal — other people can offer input, but the criteria (salary vs learning vs location vs team vs work-life balance) and weights are yours alone. Pairwise comparisons force you to confront real trade-offs instead of giving everything high scores.
Not currently. Decisio is iOS-only (iPhone and iPad). If cross-platform matters for you, ChoiceMap covers both iOS and Android.
