Read full descriptionHide full description
KrisKompass helps households understand and improve their preparedness before everyday services are disrupted. Describe your household, the resources you have available and the practical options around you. KrisKompass turns that information into structured overviews that support reflection, planning and informed decisions. Explore key areas of household preparedness: • Water • Food • Heat and energy • Hygiene • Medicine • Information • Social support • Evacuation and movement Short interactive scenarios let you practise making decisions as conditions change. There are no predetermined “correct” answers. The purpose is to help you recognise trade-offs, uncertainty and the point at which a plan may need to change. KrisKompass does not replace official information, emergency services or professional medical advice. Always follow instructions from the relevant authorities during an emergency. No account is required. The preparedness information you enter is stored locally on your device. Photo access is optional and is used only if you choose an image as a personal map. The app can be used in Swedish or English.

Everything your household needs to stay prepared, in one place. Sonalog combines rolling-stock supply management with a printable home emergency card. WHAT YOU CAN DO - Track supplies and get expiry alerts: manage water, food, hygiene, medical, power and information items with best-before dates. Choose how many days ahead you are notified (30 / 14 / 7) and at what time of day. - Home screen widget: see up to three items expiring soon without opening the app (free). - Estimate what you need: from your household size and age groups, Sonalog estimates water and food amounts and shows the gap against what you have. Pick a unit (L, mL, bottles, meals, packs) so "six 2 L bottles" counts as 12 L. - Go-bag checklist: check off what you have packed, and rename items freely. - Emergency contacts, meeting place and shelter notes, with optional fields for allergies, regular medication and a family doctor. - Backup and restore: export everything to a single file and restore it when you change devices or reinstall (free). - Emergency card PDF (Full Access): household, target amounts, contacts, meeting place, stock summary and go-bag list in one printable page. Items you have not packed yet are printed as "not ready". - Pocket cards (Full Access): a business-card sized emergency card for each family member. WHY SONALOG - Fully offline: everything stays on your device. No data collection, no transmission. - No account required. - One-time purchase, not a subscription. PLEASE NOTE Sonalog helps you record and manage household supplies and emergency information. The amounts shown are general guidelines; the app does not decide whether to evacuate and does not provide medical judgement. Always follow official local guidance and professional advice.

Verdict
The clearest difference is in-app purchases: KrisKompass at none against Sonalog's 1. KrisKompass also leads on update cadence (daily vs every 5 weeks) and iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
