Ball python morph calculator, feeding log, shed & weight tracker. No account.
Read full description
Scalewell is the reptile care tracker for keepers and breeders: log feedings with one tap, see when the next shed is coming, follow the weight curve and calculate what a pairing will hatch. Calm, fast and private. No account, no ads, works offline.
FEED WITH ONE TAP
• "Feed today" shows every animal that is due. Tap Fed and you are done.
• Fed button right in the notification and on the home screen widget, no need to open the app.
• Log any other date in one tap: Today, Yesterday, 2 days ago or the calendar.
• Refusals and regurgitation are tracked. After a refusal Scalewell suggests a new try sooner and shows the streak.
• Pause reminders during winter fasting or breeding season.
• Feeding intervals per species and life stage from published care sheets, every number with a "Why?" and its source.
SHED PREDICTION THAT LEARNS
• Log a shed and Scalewell predicts the next window.
• After two sheds it learns your animal's own rhythm.
• Eyes cloudy? Mark "in blue" and the window moves to the next days.
• Stuck sheds are flagged so you can check humidity.
BALL PYTHON MORPH CALCULATOR
• Recessive, co-dominant (incomplete dominant) and dominant genes.
• Allelic groups done right: BEL complex (Mojave × Lesser = Blue-Eyed Leucistic), Yellow Belly complex (Highway, Ivory), Albino/Candy, and for corn snakes Amel/Ultra and Motley/Stripe.
• 66% and 50% possible het per animal, trade names like Bumble Bee or Killer Bee recognized.
• Lethal or unproven homozygous forms (Spider, Champagne) are removed, with a warning.
• 89 genes for ball python, leopard gecko, corn snake and bearded dragon, each with sources. Tested against 29 documented pairings.
• Pick your own animals as parents or enter any genes.
• Share a card "Possible babies of this pairing".
WEIGHT CURVE
• Weigh in grams, from a 3 g gecko hatchling to a 25 kg boa.
• Trend per month, warning on weight loss from the recent peak.
• Feedings and sheds on the same timeline (Pro).
BREEDING
• Clutches with good eggs, incubation progress and hatch window from species data.
• Live-bearing species (boa, blue-tongued skink) with gestation from the post-ovulation shed.
YOUR DATA STAYS YOURS
• Everything is stored on your phone and moves with your Android backup.
• Free backup file you can restore on any phone, so a new phone never costs you your records.
• PDF record for vets and buyers, CSV for spreadsheets (Pro).
• Restore always works, nothing is overwritten.
